Description
Foreliggende oppfinnelse angår visse nye glycolsubstituerte alkylsilaner som er nyttige som bestanddeler av hydrauliske væsker, og hydrauliske væsker inneholdende slike forbindelser,
særlig hydrauliske væsker med høyt kokepunkt og høy dampsperretemperatur.
Hydrauliske væsker basert på glycolethere har vært
anvendt i mange år i f.eks. bremsesystemer og clutchsystemer for kjøretøyer og er fremdeles den alminneligst anvendte type av væske. ue spesifikasjoner og kvalitetsstandarder som er fast-
satt av produsenter av hydrauliske systemer og ikKe-kommersieile organisasjoner som Society of Automotive Engineers og US Department of Transportation, er imidlertid blitt stadig strengere. Spesielt er det oppstått et behov for væsker med høyt kokepunkt og, hvilket er viktigere, høy dampsperretemperatur, både for væsken slik den leveres av produsenten og for væsken i nærvær av vann. Glycolether-baserte væsker er kjent for å være mangelfulle i denne hen-seende på grunn av væskenes hygroskopisitet, hvilket fører til absorpsjon av vann fra atmosfæren. Dette nedsetter igjen kokepunktet og dampsperretemperaturen for væsken, og med lengere tids anvendelse bygger vanninnholdet i væsken seg opp til et nivå ved hvilket kokepunktet og dampsperretemperaturen nedsettes i farlig grad. Når væsken utsettes for varme, f.eks. utviklet ved sterk bremsing, kan den koke eller fordampe i tilstrekkelig grad til å bevirke alvorlig bremsesvikt.
Hydrauliske væsker med lav hygroskopisitet er blitt utviklet, basert på glycolethere, for å overkomme dette probiem.
Slike væsker er relativt ufølsomme overfor luftfuktighet, men er dyrere en glycoiether-baserte væsker og har visse tekniske ulemper, f.eks. er deres viskositetsegenskaper dårligere enn for giycol-ether-baserte væsker. Anvendelsen av disse lavhygroskope væsker har følgelig hovedsakelig vært begrenset til de tilfeller hvor ønskelige egenskaper som høyt kokepunkt og høy dampsperretempera-
tur menes å overveie deres ulemper. Andre typer av vannufølsomme væsker har også vært utviklet. Allikevel prøver produsenter fremdeles å finne frem til nye væsker som forener så mange som mulig av de ønskelige egenskaper både hos glycolether-baserte væsker og lavhygrosopisitetsvæsker, og som helst også har enda høyere kokepunkt og/eller dampsperretemperatur enn de lavhygroskopiske væsker.
I nyere tid har det vært en økende tendens til å anvende
i kjøretøyer ett enkelt hydraulisk system for å drive utstyr som kraftstyring, støtdempere og bremser, som hittil er blitt for-
synt ved hjelp av separate hydrauliske systemer. Dette har skapt alvorlige problemer med hensyn til sammensetningen av den hydrauliske væske. Mineralolje-baserte væsker som hittil er blitt anvendt i kraftstyresystemer og støtdempere, er tilfredsstillende med hensyn til nitril- og kloroprengummi som anvendes i forseglinger og pakninger i slike systemer, men er meget skadelige overfor de naturlige gummier og styren/butadien-gummier som anvendes i hydrauliske bremse- og clutchsystemer. Dette fører til stor svelling av de sistnevnte forseglinger, hvilket kan føre til alvorlig feilfunksjon av bremse- eller clutchsystemer. På den annen side har væskene som hittil har vært anvendt i bremse- og clutchsystemer, som vanligvis er basert på glycoler, glycolethere og/eller glycoletherestere, og som har virket tilfredsstillende i slike systemer, en skadelig virkning på nitril- og kloroprengummi-pakninger anvendt i kraftstyresystemer og støtdempere, hvilket kan føre til feilvirkning. Hva biler og andre kjøretøyer angår har driftssikkerheten, som er alminnelig ønskelig for alle mekaniske anordninger, øket i viktighet til et ufravikelig krav ut fra sikker-hetshensyn. Det er derfor oppstått et behov for en væske som kan anvendes på tilfredsstillende måte i et sentralt system som regul-erer driften av en rekke forskjellige delsystemer.
Man har nu funnet frem til visse nye silanforbindelser som er nyttige som bestanddeler av hydrauliske væsker for hydrauliske bremser og clutchsystemer og også for sentrale hydrauliske systemer. Disse forbindelser oppviser forbedrede gummisvelningsegenskaper med hensyn til en rekke naturlige og syntetiske gummier som anvendes i hydrauliske systemer, og de er også relativt vann-uføls-somme.
Ved hjelp av oppfinnelsen fremskaffes således nye glycol-. substituerte alkvlsilaner som antas å ha den qenerelle formel:
hvor
(a) R er alkyl, idet substituentene R kan være like eller
forskjellige
(b) R"*" er en gruppe med formelen: ;;idet substituentene R kan være like eller forskjellige, (c) R 2 er hydrogen, methyl eller ethyl, idet substituentene ;R 2 kan være like eller forskjellige, ;(d) R 3 er alkyl, idet substituentene R 3 kan være like eller ;forskjellige, ;(e) R 4 er radikalet av en diol eller polyol, ;5 1 5 ;(f) R er som R eller R, idet substituentene R kan være like ;eller forskjellige, og ;(g) n er et helt tall fra 1 til 10, ;hvilke glycolsubstituerte alkylsilaner er erholdt ved omsetning på i og for seg kjent måte av et di- eller triklorsilan med formelen: ;;hvor R er alkyl, og X er klor eller R, med en diol eller polyol ;4 4 ;med formelen HO-R -0H hvor R er radikalet av en diol eller polyol, og en glycol-monoether med formelen: ;;2 3 ;hvor R , R og n er som ovenfor angitt. ;Indeksen n er fortrinnsvis fra 1 til 6, særlig fra 1 til 4. ;Likeledes tilveiebringes det nye hydrauliske væsker som inneholder én eller flere glycolsubstituerte alkylsilaner som ovenfor angitt. ;I tilfellet av glycol-substituerte alkylsilaner for anvendelse i hydrauliske bremse- og clutchsystemer er det fore-3 5.5 ;trukket at gruppene R, R og R (når R er alkyl) er relativt kortkjedede alkylgrupper, f.eks. med fra 1 til 4, og helst 1 eller 2, carbonatomer, for å nedsette gummisvelningsvirkningen på forseglinger og pakninger anvendt i slike systemer. Når de imidlertid anvendes i et sentralsystem, kan det være mere ønskelig å frembringe et kompromiss mellom behovene, som ofte står i konflikt med hverandre, for hver av de forskjellige forseglings-og pakningsmaterialer. I dette tilfelle kan noen, eller alle, av gruppene R, R 3 og R 5 ( når R 5er alkyl) være alkylgrupper med lengre kjeder, f.eks. inntil 6 eller endog 8 carbonatomer. ;De glycolsubstituerte alkylsilaner ;ifølge" foreliggende oppfinnelse -kan lett fremstilles ut fra alkyl-klorsilaner ved omsetning med glycoler, andre dioler, polyoler, glycol-monoalkylethere eller alkanoler ettersom det pas-ser under anvendelse av kjente metoder. De kan således fremstilles ved å omsette det passende di- eller tri-klorsilan med en diol eller polyol og en glycol-monoether. Således gir omsetningen av dialkyl-diklorsilan med en glycol-monoether med formelen: - ;og med en glycol med formelen: en forbindelse med formelen: ;Alternativt kan et alkyl-triklorsilan omsettes med en glycol-monoether og en glycol med formelen: ;HO-(CH2-CH2-0>nH ;for å danne en forbindelse med formelen: ;;Omsetning av glycolen og glycol-monoetheren med alkyl-klorsilanet kan utføres samtidig i et enkelt fceaksjonstrinn. En slik enkeltrinnsreaksjon kan være mere bekvem, men er vanskeligere å regulere og derfor foretrekkes etter hverandre følgende reak-sjoner, helst under anvendelse av glycolen i det første trinn. ;Istedenfor glycolen kan et dihydroxybenzen som p-hydroxy-fenol, eller andre dioler som neopentylglycol, eller en polyol som trimethylol-propan, pentaerythritol, dipentaerythriol eller et trihydroxybenzen anvendes for å danne forbindelser i hvilke to eller flere siliciumatomer er bundet sammen over gruppen-O-R^-O-, som er resten av diolen eller polyolen. I dette tilfelle kan R^ ha én eller flere gjenværende hydroxylgrupper. Alternativt kan tilstrekkelig klorsilan anvendes til å reagere med alle hydroxylgrup- ;pene i polyolen slik at ;;innføres istedenfor de gjenvær- ;ende hydroxylgrupper. ;Ved fremstillingen av de hydrauliske væskebestanddeler ifølge oppfinnelsen kan reaksjonen av et klorsilan med en hydroxyl-gruppe (for å innføre enten én eller flere glycol-monoether-rester eller gruppen -0-R^-O- i molekylet) utføres i nærvær av en syre-akseptor for å nøytralisere frigjort hydrogenklorid. Særlig foretrukne syreakseptorer er tertiære baser som pyridin. For å sikre i det vesentlige fullstendig overføring foretrekkes det vanligvis å anvende et lite, f.eks. 10 %, overskudd av glycol-monoether-utgangsmaterialet. ;De glycolsubstituerte alkylsilan-hydrauliske væskebestanddeler kan anvendes som et additiv, som grunnmateriale eller som en bestanddel av en blanding av grunnmaterialer. De anveridfce mengder kan derfor variere over et meget vidt område. Når de anvendes som et grunnmateriale vil de gxycolsubstituerte alkylsilaner utgjøre en hoveddel av den hydrauliske væske, f.eks. fra 75 % eller 80 % til 99 vekt%, beregnet på totalvekten av den hydrauliske væske. Resten av den. hydrauliske væske kan bestå av konvensjonelle tilsetninger for hydrauliske væsker, som er mere fullstendig beskrevet i det etterfølgende, og/eller små mengder av andre grunnmaterialer for hydrauliske væsker, som også er beskrevet mere fullstendig i det etterfølgende. ;Anvendt som en bestanddel av en blanding av grunnmaterialer vil den totale blanding av grunnmaterialer likeledes utgjøre hovedmengden av den hydrauliske væske. I dette tilfelle kan grunn-materialene være overveiende et. eller flere glycolsubstituerte alkylsilaner blandet med en mindre mengde av én eller flere andre grunnmaterialer, av den i det etterfølgende beskrevne type, for å modifisere egenskaper av de glycolsubstituerte alkylsilaner. Den hydrauliske væske kan således inneholde f.eks. 55 - 70 vekt% av én eller flere glycolsubstituerte alkylsilaner beregnet på totalvekten av den hydrauliske væske. Alternativt kan et eller flere andre grunnmaterialer være modifisert ved blanding med en mindre mengde glycolsubstituerte alkylsilaner slik at den hydrauliske væske inneholder f.eks. fra 20 % til 40 vekt% glycolsubstituerb alkylsilan. Dessuten kan et kompromiss mellom egenskapene for de glycolsubstituerte alkylsilaner og de andre væsker oppnås ved blanding i omtrent like mengder for å få væsker inneholdende fra 40 ;til 55 % glycolsubstituert alkylsilan. ;Når de anvendes for å'nedsette følsomheten av hydrauliske væsker, og særlig kokepunktet og damps<p>erretemperaturen for væskene, anvendes de glycolsubstituerte silaner fortrinnsvis i mengder i om-rådet fra 20 til 55 %, og helst 20 - 40 %. Alternativt, men mindre fordelaktig, kan en forbedring også oppnåes under anvendelse av lavere mengder av glycolsubstituerte silaner, f.eks. fra 0,5 % til 15 % eller 20 vekt%, beregnet på totalvekten av de hydrauliske væsker. Hovedmengden av slike væsker vil utgjøres av et eller flere grunnmaterialer som beskrevet i det etterfølgende. ;Når de glycolsubstituerte alkylsilaner anvendes som bestandel av en blanding av grunnmaterialer, kan de erholdte hydray-liske væsker inneholde konvensjonelle tilsetninger for hydrauliske væsker på lignende måte som når grunnmaterialet i det vesentlige består av de glycolsubstituerte alkylsilaner. På lignende måte kan de glycolsubstituerte alkylsilaner når de anvendes som en tilsetning, om ønskes, anvendes sammen med konvensjonelle tilsetninger for hydrauliske væsker. ;Grunnmaterialer med hvilke de glycolsubstituerte alkylsilaner kan blandes, eller med hvilke de kan anvendes som tilsetninger, innbefatter glycoler, glycolethere, glycolestere, glycol-orthoestere og boratestere. Glycolether-grunnmaterialer er vel kjente og passende eksempler på disse er de som vanligvis anvendes i hydrauliske væsker. De foretrukne glycolester-grunnmaterialer er de som har de generelle formler: ;hvor R<6> er en rettkjedet eller forgrenet alkylengruppe med minst 2, fortrinnsvis 2-8, carbonatomer, hver R<7>, som er like eller forskjellige, er en alkylgruppe med 1-4 carbonatomer eller en fenylgruppe, hver R° som er like eller forskjellige, er ethylen, propylen eller butylen, hver x, som er like eller forskjellige, er 0, 1, 2 eller 3, hver R^, som er like eller forskjellige, er ethyl eller methyl, hver B?~ ®, som er like eller forskjellige, er ethylen eller propylen, og y er et helt tall, fortrinnsvis et tall slik at det totale antall av carbonatomer i gruppen ■f10O>y er fra 4 til 12, fortrinnsvis fra 4 til 9. ;Carboxylsyreesterne med formel I er beskrevet i britisk patent 1 083 324. Estere som passende kan anvendes i foreliggende oppfinnelse er succinatene, glutaratene, adipatene, azelatene, se-bacatene, isosebacatene og nylonatene av methyl-, ethyl-, propyl- ;og butyl-monoethere av mono-, di- og tri-ethylenglycoler beskrevet i britisk patent 1 0 83 324, idet nylonatene, særlig dimonomethyl-etheren av diethylenglycolnylonatene,er særlig foretrukket. ;Glycol-diesterne med formel II er kjente forbindelser og de foretrukne glycol-diestere er glycol-dipropionatene beskrevet i britisk patent 1 249 803. Det foretrekkes at de hydrauliske væsker omfatter ikke mere enn 50 vekt% av glycol-diesterne, idet den even-tuelle rest av carboxylsyreesterbestanddelen er esterne med formel I. ;Mange varianter av boratester-grunnmaterialer er kjente, og disse kan betegnes med de følgende generelle formler: ;hvor hver R , som er like eller forskjellige, er en rettkjedet eller forgrenet alkylengruppe, hver R 12, som er like eller forskjellige, er alkyl, hver p, som er like eller forskjellige, er et helt tall, q er et helt tall fra 2 til 6, R 13 er resten av en di-eller poly-hydroxy-organisk forbindelse med en rekke reaktive hydroxylgrupper lik q, og hver R<1>^, som er like eller forskjellige, er resten av en di-hydroxy-organisk forbindelse, hvilken rest er bundet til hvert boratom over et oxygenatom. ;Disse boratestere er mere fullstendig beskrevet i britisk patent 1 341 901. ;Andre grunnmaterialer som kan anvendes, er glycolortho-esterne beskrevet i britisk patent 1 330 468 og som har den generelle formel: ;hvor R^ er hydrogen, alkyl med 1-5 carbonatomer eller det samme som OR"^; hver R <*>V som er like eller forskjellige, er alkyl med 1-4 carbonatomer, en oxyalkylenglycol-monoether-gruppe eller en polyoxyalkylenglycol-monoether-gruppe med fra 2 til 20 alkylenoxy-enheter, forutsatt at minst én R<16> er en oxyalkylenglycol-monoether-17 gruppe eller en polyoxyalkylen-glycolmonoethergruppe, og R er alkylen med 1-12 carbonatomer, med det forbehold at R"^ da er det samme som OR<16> eller R<17> er gruppen -fO-R 0>„, hvor hver R , som er like eller forskjellige, er alkylen med 2-8 carbonatomer, og z er et helt tall fra 1 til 6. Det henvises til britisk patent 1 330 468 for ytterligere detaljer om slike glycol-orthoestere.
Ved en særlig foretrukket utførelsesform av foreliggende oppfinnelse anvendes de glycolsubstituerte alkylsilaner som et grunnmateriale i hydrauliske væsker som også omfatter en liten mengde, f.eks. 1-10 vekt%, av et gummisvelningsmodifiserende middel som en ethylenglycol.
I en annen særlig foretrukket utførelsesform av oppfinnelsen anvendes de glycol-substituerte alkylsilaner, enten som en tilsetning eller som en bestanddel av en blanding av grunnmaterialer,
i hydrauliske væsker som omfatter én eller flere glycolestere av formel I og/eller II, eller omfatter en blanding av én eller flere glycolestere med formel I og/eller II med én eller flere boratestere med formel III til VII, særlig boratestere med formel III.
Typiske tilsetninger som kan anvendes i, eller sammen med, de glycolsubstituerte alkylsilaner er smøringstilsetninger valgt fra ricinusolje eller ricinusolje behandlet på forskjellige måter, f.eks.:
"Firsts Castor Oil",
Ricinusolje til spesifikasjon DTD72.
Blåst ricinusolje, dvs. ricinusolje blåst med luft eller oxygen under oppvarming.
"Special Pale Blown Castor Oil", dvs. en lignende blåst ricinusolje.
"Hydricin 4", dvs. en kommersielt tilgjengelig ethylen-oxyd/propylenoxyd-behandlet ricinusolje.
Andre smøringstilsetninger som kan inkorporeres i hydrauliske væsker i henhold til foreliggende oppfinnelse innbefatter boratestere, f.eks. tricresylborat og fosforholdige estere, særlig fosfater f.eks. tricresylfosfat.
De hydrauliske væsker ifølge oppfinnelsen kan også innbe-fatte mindre mengder av polyoxyalkylenglycoler eller ethere derav f.eks. de som selges under varemerket "Ucon", særlig de i LB- og HB-seriene. Passende eksempler på disse polyoxyalkylenglycoler og deres ethere og estere er gitt i britisk patent 1 055 641. Andre passende smøringsmidler er orthofosfat- eller sulfatsalter av primære eller sekundære alifatiske aminer med tilsammen fra 4 til 24 carbonatomer, dialkylcitrater med gjennomsnittlig fra 3,5 til 13 carbonatomer i alkylgruppene, alifatiske dicarboxylsyrer og estere derav, idet spesifike eksempler er:
Diamylamin-orthofosfat
Dinonylamin-orthofosfat
Diamylamin-sulfat
Dinonyl-citrat
Di-(2-ethyl-hexyl)-citrat
Polyoxyethylen-sebacat avledet av en polyoxyethylenglycol med m.v. 200
Polyoxyethylen-azelat avledet av en polyoxyethylenglycol med m.v. 200
Polyoxyethylen/polyoxypropylen-glutarat avledet av blan-dede polyoxyglycoler med gjennomsnittlig m.v. på ca. 200 Glutarsyre
Nonandisyre

Ravsyre
Decandisyre-diethylester
Decandisyre-di-2-ethyl-hexylester
Nonandisyre-di-isooctylester
Umettede alifatiske syrer og deres salter kan også anvendes, f.eks. oljesyre eller kaliumricinoleat.
Korrosjonsinhibitorer som kan anvendes i foreliggende oppfinnelse, kan velges fra heterocykliske nitrogenholdige forbindelser, f.eks. benzoetriazol og benzotriazol-derivater som dem som er beskrevet i britisk patent 1 061 904, eller mercaptobenzothiazol. Mange aminer eller derivater derav er også egnet som korrosjonsinhibitorer, f.eks. di-n-butylamin, di-n-amylamin, cyclohexylamin, morfolin, triethanolamin og oppløselige salter derav, f.eks. cyclohexylamin-carbonat.
Fosfiter er også gode korrosjonsinhibitorer, f.eks. tri-fenyl-fosfit, di-isopropyl-fosfit og visse uorganiske salter kan inkorporeres f.eks. natriumnitrat.
Andre tilsetninger som kan inkluderes, er antioxydanter som diarylaminer, f.eks. difenylamin, p,p'-dioctyl-difenylamin, fenyl-a-nafthylamin eller fenyl-B-nafthylamin. Andre egnede oxy-danter er de som vanligvis betegnes som hindrede fenoler som eksem-plifisert av
2,4-dimethyl-6-t-butyl-fenol
2,6-di-t-butyl-4-methyl-fenol
2,6-di-t-butyl-fenol
1,1-bis-(3,5-di-t-butyl-4-hydroxyfenyl)-methan 3,3',5,5'-tetra-t-butyl-4 ,4'-dihydroxydifenyl 3- methyl-4,6-di-t-butyl-fenol
4- methyl-2-t-butyl-fenol
Nok andre tilsetninger som kan anvendes, er fenothiazin og dets derivater, f.eks. de som har alkyl- eller arylgrupper bundet til nitrogenatomet eller til arylgruppene i molekylet.
Andre tilsetninger som kan anvendes innbefatter alkylen-oxyd/ammoniakk-kondensasjonsprodukter som korrosjonsinhibitorer, f.eks. propylenoxyd/ammoniakk-kondensasjonsproduktet beskrevet i britisk patent 1 249 803. Andre smøringstilsetninger som kan anvendes, er komplekse estere som dem som selges under varemerket "Reoplex 641" og som også er beskrevet i britisk patent 1 249 803. Dessuten kan langkjedede (f.eks. Ciri ,„) primære amin-korrosjons-iu—lo
inhibitorer og polymeriserte kinolinharpiks-antioxydanter, som be-srkevet i britisk patent 1 249 803, anvendes, og eksempler på slike aminer og harpikser er de kommersielt tilgjengelige materialer "Armeen 12D" henholdsvis "Agerite resin D".
Konvensjonelle tilsetninger som dem som er beskrevet ovenfor, anvendes vanligvis i små mengder som 0,05 - 10 %, f.eks. 0,1 - 2 vekt%.
Det har vist seg at tertiære aminer har fordeler fremfor primære og sekundære aminer som korrosjonsinhibitorer slik at hydrauliske væsker i henhold til foreliggende oppfinnelse inneholdende tertiære aminer viser mindre tilbøyelighet til geldannelse, særlig i tilfelle av hydrauliske væsker hvor R^ er som gruppen r!. En særlig foretrukket utførelsesform av foreliggende oppfinnelse fremskaffer således hydrauliske væsker inneholdende et eller flere tertiære aminer, eller derivater derav, med den generelle formel: hvor hver R 19, som er like eller forskjellige, er alkyl, fortrinnsvis med 1-6 carbonatomer, aryl, alkaryl eller aralkyl, fortrinnsvis med 6-12 carbonatomer, eller en gruppe med den generelle formel:
hvori R 20-gruppen eller -gruppene er rettkjedet eller forgrenet
21 alkylen, fortrinnsvis ethylen, propylen eller butylen, R er hydrogen eller alkyl fortrinnsvis inneholdende 1-6 carbonatomer, og m er et helt tall fra 1 til 6, eller hvilke som helst to grupper R 19 kan sammen danne et syklisk system forutsatt at hvis nitrogen-
19
atomet derved blir tertiært, mangler den tredje gruppe R
Når to av gruppene i ovenstående generelle formel sammen danner et syklisk system, inneholder dette fortrinnsvis 4-6 carbonatomer i ringen. Videre kan heteroatomer som oxygen og nitro-gen også være tilstede i ringen, som f.eks. i tertiære aminer avledet av morfolin, henholdsvis piperazin; det er imidlertid ønskelig at ytterligere nitorgen-heteroatomer også bør være tertiære som i 1,4-dimethylpiperazin. Eksempler på tertiære aminer i henhold til ovenstående generelle formel hvor de to grupper R^9 sammen gjør nitrogenatomet tertiært, idet den tredje gruppe R 19 således mangler, er pyridin og kinolin.
Særlig foretrukne tertiære aminer for anvendelse i de hydrauliske væsker ifølge oppfinnelsen er triethylamin, triethanolamin, trifenylamin og aminer med formelen:
og aminer med denne formel er kommersielt tilgjengelig under han-delsnavnet "Propylan A350".
De tertiære aminer kan anvendes i en mengde på fra 0,05 til 3,0 0 vekt%, beregnet på totalvekten av den hydrauliske væske.
Uansett den nøyaktige sammensetning er det ønskelig at de hydrauliske væsker ifølge oppfinnelsen har en kinematisk viskositet ved -40° C og ikke over 5000 est, særlig ikke over 2000 est. Det er også ønskelig at de hydrauliske væsker har et kokepunkt på minst 260° C.
Foreliggende oppfinnelse vil nu bli belyst ytterligere
med de følgende eksempler.
Eksempel 1
150 g (1,0 mol) triethylenglycol og 158 g (2,0 mol) pyridin ble blandet og den dannede blanding tilsatt til 258 g (2,0 mol) dimethyl-diklorsilan oppløst i 3,0 1 toluen i løpet av 12 minutter. Under tilsetningen dannes et tett hvitt bunnfall og en eksoterm reaksjon iakttas. Temperaturen på reaksjonsblandingen ble holdt under 42° C under tilsetningen.
Reaksjonsblandingen ble så oppvarmet til ca. 100° C i 4 timer og fikk så avkjøles. Til det erholdte første trinns produkt ble tilsatt en blanding av 361 g (2,2 mol) triethylenglycol-mono-methylether og 174 g (2,2 mol) pyridin i løpet av 20 minutter i løpet av hvilken tid en eksoterm reaksjon ble iakttatt. Under den eksoterme reaksjon ble temperaturen holdt under 35° C, men deretter ble reaksjonsblandingen oppvarmet til ca. 100° C i 4 timer. Det erholdte produkt fikk lov til å avkjøle og det ble så frafiltrert, og filterkaken ble vasket med ytterligere toluen. Oppløsningsmid-let (toluen) ble fjernet fra filtratet under anvendelse av en rote-rende fordamper og produktet avdrevet til 180O c/0,05 torr. Slutt-produktet (utbytte 333,0 g) var en klar, meget blek gul væske inneholdende 11,1 vekt% Si og 0,03 vekt% Cl (teoretisk 9,5 %, henholdsvis 0) .
Eksempel 2- 25
Videre fremstillinger ble utført på lignende måte som i eksempel 1, idet hovedforskjellene er angitt i tabell 1.

IR-spektra for produktene fra de foregående eksempler
ble alle funnet å stemme med at det ventede produkt var erholdt.
For å bestemme egnetheten av produktene fra de foregående eksempler for anvendelse i hydrauliske væsker ble følgende prøver utført. (a) Kinematiske viskositeter ved -40° C, i centistoke, ble målt på den måte-som er angitt i SAE J1703c-spesifikasjonen. (b) Prøver ble underkastet D.O.T. fuktighetsprøven i henhold til fremgangsmåten angitt i FMVSS 116-spesifikasjonen og damps<p>erre-temperaturene for prøvene ble målt. 'Bamp<sp>erretemperaturene ble bestemt på den måte som er beskrevet i britisk patent 1 341 901. (c) Gummisvelningsegenskaper ble målt ved å anbringe gummi-prøver 25 mm x 25 mm x 3 mm i 60 ml krukker som hver inneholdt 50 ml forsøksvæske i 3 dager hvorunder temperaturen ble holdt ved 70° C for nitril- og naturgummiprøvene og ved 120° C for styren/butadien-gummiprøvene. Etter forsøket ble den prosentvise volumøkning for hver av gummiprøvene målt.
Resultatene fra disse prøver er angitt i tabell II. Dessuten ble den hydrolytiske stabilitet av en rekke av produktene bestemt i henhold til "Water Tolerance tests" som angitt i SAE J1703c-spesifikasjonen, og alle produktene prøvet på denne måte tilfredsstillet stabilitetsstandardene som kreves ved denne prøve.
