Description
Inhibitor ved behandling av metaller med sure midler.
I teknikken blir metalloverflater ofte
behandlet med sure midler, spesielt mineralsyrer, for å fjerne oksydlag o. 1. For å hindre et direkte angrep på metallet, anvender man derunder beskyttelsesmid-ler, der som regel sammenfattes under be-tegnelsen «sparebeiser». Eksempelvis blir det i beiseanlegg eller hvor jern skal be-fris for rust tilsatt stoffer som i størst mulig grad skal hindre angrep av syrene på det blanke, ikke korroderte metall. Den samme metode kan også anvendes ved andre metaller, f. eks. ved sink og aluminium.
De krav som i dag, etter lengere tids
utvikling stilles til slike beskyttelsesstoffer, er store og mangesidige. Foruten å ha best mulig beskyttelse mot syrekorrosjonen ved anvendelse av minst mulig mengde, forlan-ger man at gode midler av denne art også skal ha vedvarende virkning i den forstand at syrebadene kan holdes i drift i lang tid. Midlene skal være virksomme innenfor vide temperatur- og konsentrasjonsområder, og skal såvidt mulig også gi like god beskyttelse i forbindelse med de forskjelligste beisesyrer og de forskjelligste jernsorter. Foruten å være minst mulig flyktige med vann- og syredamper, skal nutidens beise-tilsetninger ikke være giftige, og de skal ved bruk ikke utvikle noen driftsforstyr-rende gasser og heller ikke frembringe uheldig lukt, en mangel som hefter ved mange av de eldre svovelholdige beise-midler.
Ansøkerne har funnet at organiske sulfosyrer av den alminnelige formel
resp. salter derav har utmerkede egenska-per som korrosjonshindrende midler, og i
høy grad oppfyller nesten alle de ovenfor nevnte fordringer. I den ovenfor angitte formel betyr G en organisk rest, som har et utelukkende med heteroatomer forbundet kullstoffatom, som over et svovelatom er forbundet med resten R-S03H, og hvor R betyr en toverdig alifatisk rest, som også kan være substituert.
Sulfonsyrer eller salter derav som i henhold til oppfinnelsen kan anvendes som korrosjonshindrende middel tilsvarer i det vesentlige de nedenstående konstitusjons-formler, i hvilke de frie bindinger kan væ-re mettet med vannstoff eller med alifati-ske, cykloalifatiske eller aromatiske kull-vannstoffrester. Kullvannstoffrestene kan også være forbundet innbyrdes og kan eventuelt inneholde substituenter eller yt-terligere heteroatomer eller heteroatom-grupper:
Til grunn for denne konstitusjon ligger f. eks. sulfonsyrer som avledes av tiourin-stoff, samt ved forbundet kullstoff kjede sådanne som avledes av 2 - tioimidazoler resp. -benzimidazoler.
Til grunn for denne konstitusjon ligger f. eks. sulfonsyrer som avledes av 2-merkap-totiazoler resp. 2-merkaptobenztiazoler og av rhodaniner.
Denne konstitusjon tilsvarer sulfonsyrer som avledes f. eks. fra 2-tiobenzoksazoler og 2-tiokumazoler (2-tiobenzo-metoksa-ziner).
Sulfonsyrer av denne konstitusjon avledes f. eks. fra ditiokarbaminsyrer.
Til grunn for sulfonsyrer av denne konstitusjon ligger tioxanthogensyrer resp. tri-tiokullsyrer.
Sulfonsyrer av denne konstitusjon er deri-vater av xanthogensyrer.
Sulfonsyrer av denne konstitusjon er deri-vater av karbaminotiolsyrer.
Disse sulfonsyrer resp. deres salter kan på enkel måte fås med godt utbytte f. eks. ved å omsette de tilsvarende sulhydryl-resp. enoliserbare tiokarbonyl-forbindelser med cykliske anhydrider av oksyalkansul-fonsyrer (sultoner).
Nedenfor angis noen eksempler på salter av disse sulfonsyrer, som svarer til de ovenfor angitte konfigurasjoner og som i henhold til oppfinnelsen kan anvendes som korrosjonshindrende tilsetninger: Be-tairier av isotiurinstoff-S-butan-co-sulfon-syre samt av N-fenyl-isotiourinstoff-S-propan-oj-sulfonsyre og liknende; 2 mer-kapto-benztiazol-S-propan-co-sulfonsurt kalium; rhodaninsyre-S-n-propylester-æ-sulfonsurt natrium; 2-tiobenzoksazol-S-propan-oj-sulfosurt natrium; 2-tio-me-toksazin-S-butan-sulfosurt kalium; N,N-dimetyl-ditio-karbaminsyre-n-propylester-co-sulfosurt natrium; N,N-dietyl-metylen-ditiokarbaminsyre-n-propylester-cu-sulfosurt natrium; N-p-tolyl-ditiokarbaminsyre -n-propylester-to-sulfosurt kalium; ditiokarbaminsyre-n-prpylester- sulfosurt kaT lium; S-fenyl-tritiokullsyre-n-propylester-co-sulfosurt natrium; tritio-kullsyre-bis-propylester-co-sulfosurt natrium ; isopropyl-xantogensyre-n-butyl-ester-(D-sulfosurt natrium; n-butyl-xanto-gensyre-n-propylester-co-sulfosurt natrium; karbamino-tiolsyre-n-propylester-sulfosurt kalium, og liknende. I stedet for natrium, resp. kaliumsalter, kan det anvendes også andre salter av anorganiske eller organiske baser.
Den sterke virksomhet av disse sulfosyrer resp. de tilsvarende salter fremgår av de i nedenstående tabell angitte verdier, ved hvis bestemmelse man går frem på følgende måte: Jernblikk av 18 cm2 overflate ble an-brakt i 2n saltsyre resp. 2n svovelsyre. An-grepet på metallet ble fortløpende fulgt ved å måle den dannede vannstoffmengde. Av korrosjonshastigheten hos systemene jern/2n saltsyre resp. jern/2n svovelsyre ble det ved 23° opptatt sammenliknings-verdier, med hvilke de senere målte korro-sjonshastigheter av systemene jern/2n saltsyre + tilsetning resp. jern/2n svovelsyre + tilsetning ble sammenliknet pro-sentvis. Tilsetningen anventes i alle til-felle i en konsentrasjon av 1 g/l.
Ved de produkter som i henhold til nedenstående tabell er blitt undersøkt med hensyn på korrosjonshindrende virkning dreier det seg om følgende forbindelser: I. Ditiokarbaminsyre-N-propylester-co-sulfosurt natrium. II. N,N-dimetyl-ditiokarbaminsyre-n-propylester-co-sulfosurt natrium. III. N,N-dietyl-ditiokarbaminsyre-n-propylester-a»-sulfosurt natrium. IV. N,N-dietyl-ditiokarbaminsyre-n-butylester-co-sulfosurt natrium. V. N,N-diisoporpyl-ditiokarbaminsyre-n-propylester-oj-sulfosurt natrium. VI. N,N-dibutyl-ditiokarbaminsyre-propylester-co-sulfosurt natrium. VII. N,N-pentametylen-ditiokarbaminsyre-n-propylester-co-sulfosurt natrium. VIII. N-butyl-ditiokarbaminsyre-n-propylester-co-sulfosurt natrium. IX. Isopropyl-xantogensyre-n-propyl-ester-M-sulfosurt natrium. X. Butyl-xantogensyre-n-propylester-co-sulfosurt natrium. XI. Tritiokullsyre-bis-n-propylester-(D-sulfosurt natrium. XII. 2-merkaptobenztiazol-S-propan-co-sulfosurt natrium. XIII. 2-merkaptobenztiazol-S-butan-æ-sulfosurt natrium. XIV. Rhodanin-S-propan-co-sulfosurt natrium. XV. Betain av isotiourinstoff-S-pro
pan-æ-sulfosyre.
Anvendelsen av fremgangsmåten i henhold til oppfinnelsen i praksis foregår på vanlig måte. De anvendte mengder kan variere innenfor vide grenser og retter seg etter arten av det benyttede sure behand-lingsmiddel, etter metallet som skal be-handles og eventuelt også etter behand-lingstemperaturen. Som regel vil man greie seg med tilsetninger på mellom 0,01 og 0,5 pst. beregnet på de sure midler. Midlene i henhold til oppfinnelsen kan eventuelt også benyttes i blandinger med kjente korrosjonsbeskyttende midler. Som sure behandlingsmidler kommer foruten mineralsyrer også sure salter av mineral-syrene og også organiske syrer. Fremgangsmåten kan anvendes til beskyttelse av alle slags metaller som blir underkastet en behandling med sure midler for rengjø-ring, overflatebehandling, etsing o. 1.
