Description
Olje til bruk ved isolering, kjøling og varmeoverføring.
Det er kjent at isomerblandinger av
klorerte difenyler kan anvendes som isolerings- og kjøleoljer til transformatorer og som varmeoverf ørende olje til opphetning av rom. Disse oljer har alt etter høyden av kloreringsgraden forskjellig høytliggen-de eutektiske temperaturer.
Hvis oljene anvendes f. eks. som isoleringsoljer for transformatorer, som er ut-satt for meget lave temperaturer (frilufts-anlegg), er det nødvendig at isolerings- og kjøleoljene har meget lave eutektiske temperaturer. De hittil kjente isomerblandinger av klorerte difenyler med eutektiske temperaturer under —20° har den ulempe at ved meget lave temperaturer krystalliserer lett deler av isomerblandingen ut. En slik krystallisering kan forandre isolerings-oljens dielektriske egenskaper og ved be-lastning av det elektriske apparat føre til gjennomslag.
Liknende ulemper iakttas også når oljene anvendtes som varmeoverf ørere for opphetning av rom. Dette er fremfor alt tilfelle hvis opphetningen avstenges forbi-gående.
For å utsjalte denne usikkerhet ved
driften av apparatene som inneholder disse oljeblandinger, har man til slike blandinger satt oppløsningsmidler for de utkrystalliserende stoffer, f. eks. triklorbensol (se U. S. patent nr. 1.931.373 og engelsk patent nr. 493.961). Denne fremgangsmåte har imid-lertid den ulempe at homogeniteten av et påtrykket felt blir forstyrret, hvorved det opptrer en økning av tapsvinkelverdien. Dessuten fordamper det tilsatte oppløs-ningsmiddel hurtigere enn de klorerte di-
fenylisomere, slik at apparatet som er blitt fylt med slike blandinger må ettersees ofte og fra tid til annen etterfylles.
Oppfinnerne har funnet at den først og fremst krystalliserende andel av slike isomerblandinger av klorerte difenyler er p,p'-diklordifenyl. Da den eutektiske temperatur av klorert difenyl ligger desto la-vere jo mindre klorinnholdet er, opptrer utkrystalliseringen i isoleringsoljer som har lave eutektiske temperaturer. For å hindre denne krystallisering, anvender man derfor i henhold til oppfinnelsen klorerte difenyler som ikke eller i bare liten grad inneholder p,p'-diklordifenyl. Mengden av p,p'-diklordifenyl i den klorerte difenylisomer-blanding skal i henhold til oppfinnelsen ikke utgjøre mere enn 8 pst. beregnet på den samlede blanding.
Hensiktsmessig anvender man for fremstillingen av de klorerte difenyler slike metoder, ved hvilke det ikke eller bare i liten grad dannes p.p'-diklordifenyl. Egnede fremgangsmåter er f. eks. klorering av difenyl med sulfuryl-klorid, fortrinnsvis i nærvær av aluminiumklorid, eller klorering med klor i nærvær av ca. 0,5—20 pst. brunsten. Hvis man for kloreringen anvender de vanlige halogenoverførere som f. eks. Jern eller antimonklorid, underkjøler man den erholdte isomerblanding inntil det ikke ønskede p,p'-diklordifenyl krystalliserer ut, og skiller så krystallene fra ved filtrering eller sentrifugering.
En særlig fordel ved de for p,p'-diklor-fenyl frie isomerblandinger eller ved isomerblandinger som bare inneholder litt p,p'-diklordifenyl, er disses høye dielektrisitetskonstant. Mens en isomerblanding med et klorinnhold som svarer til penta-klordifenyl har en dielektrisitetskonstant på 4,4, ved 20° og 50 p/s, har den for upolart p,p'-diklordifenyl frie isomerblanding resp. en isomerblanding med en liten ikke lenger utkrystalliserende andel av p,p'-diklordi-f enyl, en dielektrisitetskonstant på ca. 6 ved 20° og 50 p/s. Som følge av disse gunstigere dielektrisitetsegenskaper kan dimensjone-ne av transformatorene og kondensatorene holdes tilsvarende mindre.
De i henhold til oppfinnelsen anvendte isomerblandinger har i alminnelighet et klorinnhold på minst 32 pst. og høyest 42 pst.
Eksempel 1.
I 154 vektdeler smeltet difenyl heller man ved en temperatur på ca. 80° C inn 472,5 vektdeler sulfurylklorid. For innledning, opprettholdelse og påskynning av kloreringen blir det etterhvert tilsatt 12 vektdeler aluminiumklorid. Det flytende råprodukt blåses ut med, luft eller en inert gass, nøytraliseres med faste eller flytende nøytraliseringsmidler f. eks. pulverisert ets-natron eller 10 pst.'s etsnatron-oppløsnin-ger og destilleres deretter i vakuum.
(Kpi3ram160—195°). Destillatet er vannklart, har et klorinnhold på 40 pst. og dets eutektikum ligger ved —26° C.
Eksempel 2.
Til 77,5 vektdeler smeltet difenyl setter man 7,75 vektdeler mangansuperoksyd (brunsten) og leder inn 41,5 vektdeler klor. Mengden av brunsten kan forhøyes til 20 pst. eller senkes til 0,5 pst. Det flytende råprodukt blir på egnet måte, f. eks. vel filtrering, befridd for brunsten resp. dé som mellomtrinn dannede manganklorider, og etter nøytralisering med alkali destilleres det i vakuum. (Kpi3]lim160—195°). Den rene isomerblanding har et klorinnhold på ca. 35 pst. og dens eutektikum ligger ved —29°.
Eksempel 3.
155 vektdeler difenyl som er tilsatt 0,2 vektdeler antimontriklorid eller en annen kjent kloroverfører blir ved innledning av klor ved 100—150° C gitt et klorinnhold på 38 pst. eller 36 pst. Fra de erholdte rå-produkter utfelles det mere eller mindre hurtig, eventuelt etter podning, en rikelig mengde krystaller. Man kan allerede befri råproduktet for krystallene eller man kan først foreta nøytraliseringen, eller man de-stillerer råproduktet og fjerner deretter krystallene ved filtrering. Krystallene har et klorinnhold på 32 pst. Den flytende isomerblanding har et noe høyere klorinnhold på ca. 36 pst., og eutektikumet ligger ved —28 til —30° C.
Claims (1)
- Anvendelse av isomerblandinger av klorerte difenyler som har et klorinnhold på minst 32 vektprosent og høyst 42 vektprosent, og som er fri for p,p'-diklordifenyl, eller bare har et lite, ikke lenger utkrystalliserende innhold av p,p'-diklordifenyl, som olje for isolering, kjøling og varmeoverføring.
