Description
Fremgangsmåte til fremstilling av hydrogenperoksyd.
Den foreliggende oppfinnelse angår en
fremgangsmåte til fremstilling av hydrogenperoksyd ved avvekslende etter hverandre følgende hydrering av eventuelt substituerte antrakinoner og oksydasjon av de
derved dannede antrahydrokinoner resp. oksantroner, i et nytt oppløsningsmiddel.
For den såkalte antrakinon-imetode til
fremstilling av hydrogenperoksyd er det allerede blitt foreslått mange oppløsnings-midler, som imidlertid for det meste bare oppfyller de stillede krav i 'utilstrekkelig grad. Et ideelt oppløsningsmiddel måtte ha følgende egenskaper:
1) Antrakinonets oppløselighet skal være stor. 2) Antrahydrokinonets oppløselighet skal være stor. 3) Oppløsningsmidlet skal være kje-misk inert, spesielt oksydasjons- og hydrerlngsbestandig. 4) Det skal såvidt mulig være et billig handelsiprodukt, som er fritt for kontaktgifter. 5) Det skal ha et høyt koke- og flamm-punkt. 6) Vannoppløseligheten skal være liten. 7) Fordelingskoeffisienten for H2O1;
skal være høy.
Denne oppregning kunne kompletteres ytterligere. De mange egenskaper som kre-ves hos et oppløsningsmiddel for antrakinon-metoden er grunnen til at man d prak-sis nesten utelukkende anvender oppløs-ningsmiddelblandinger, med hvilke man ved passende kombinasjoner av enkeltbe-standdelene forsøker å komme nær til idealoppløsningsmidlets ønskede egenskaper.
I henhold til oppfinnelsen er en fremgangsmåte til fremstilling av hydrogenperoksyd ved avvekslende etter hverandre følgende hydrering av eventuelt substituerte antrakinoner, oksydasjon av de derved dannede antrahydrokinoner og ekstrahering av det dannede vannstoffperoksyd med vann, karakterisert ved at man som oppløsningsmiddel eller oppløsningsmiddel-bestanddel for det eventuelt substituerte antrakinon og eventuelt substituerte antrahydrokinon anvender et stoff med den alminnelige formel
hvor R = H, alkyl, aryl, alkyloksy eller en karbonsyrerest. Lengden -av sidekjeden skal ikke være over 10 C-atomer, da ellers for-bindelsens viskositet blir for stor. De foretrukne aromatiske alkoholer er |3-fenyletylalkohol og fi-tolyletylalkohol, disses estere og deres enkle derivater.
Disses foretrukne oppløsningsmidler har en så stor oppløsningsevne for kinon-og hydrokinontrinnet, at de endog kan bru-kes som enkeltkomponenter for kretspro-sessen til fremstilling av hydrogenperoksyd. På grunn herav oppnås en vesentlig
forenkling ved opparbeidelsen av en brukt
«arbeidsoppløsning», hvorved man forstår
oppløsningen av den eventuelt substituerte
antrakinon i oppløsningsmidlet eller opp-løsnlngsmiddelblandingen. En videre fordel
ved oppløsningsmidlet i henhold til oppfinnelsen er dets høye kokepunkt, flamm-punkt og fordelingskoeffisient.
De nevnte oppløsningsmidler kan også
med fordel anvendes som iblandingskompo-nenter for andre oppløsningsmidler og eg-ner seg utmerket som oppløsningsmiddel
for andre reaksjonsbærere foruten etylan-trakinon, f. eks. for tert.-butyl-antrakinon,
en eller flere ganger alkylerte antrakinoner eller halogenerte antrakinoner.
Claims (3)
1. Fremgangsmåte til fremstilling av
hydrogenperoksyd ved avvekslende etter hverandre følgende hydrering av eventuelt substituerte antrakinoner, oksydasjon av de derved dannede antrahydrokinoner og ekstrahering av det dannede vannstoff
peroksyd med vann, karakterisert ved at man som oppløsningsmiddel eller oppløs-ningsmiddelbestanddel for det eventuelt substituerte antrakinon og eventuelt substituerte antrahydrokinon anvender et stoff med den alminnelige formel
hvor R = H, alkyl, aryl, alkyloksy eller en karbonsyrerest.'
2. Fremgangsmåte ifølge påstand 1, karakterisert ved, at det som oppløsnings-middel eller oppløsnlngsmlddelbestanddel anvendes tolyletylalkohol.
3. Fremgangsmåte ifølge påstand 1, karakterisert ved at det som oppløanings-middel eller oppløsningsmiddelbestanddel anvendes (3-fenyletylalkohol.
