1,2-octanediol gukoresha hamwe na synthesis
Iriburiro:
1,2-octanediol ni ibara ritagira ibara cyangwa ryera, kandi aho ritetse (℃) munsi ya 1330Pa ni 131-132 ℃.1,2-octanediol irashobora kuvangwa nubumara butandukanye bwimiti kama muburyo ubwo aribwo bwose, kandi bifite aho bihurira.
Imyiteguro:
Ongeramo aside irike na hydrogen peroxide kuri reaktor ifite ibikoresho byo gukurura hamwe na termometero hamwe na tank yo murwego rwohejuru, tangira kubyutsa, hanyuma wongereho 1-octene.Nyuma yo kongeramo, igisubizo kivanze cya reaction kibikwa muminota 100, hanyuma kigahumeka munsi yumuvuduko ukabije Acide namazi, hanyuma ukongeramo hydroxide yumuti wa sodiumi ukurura kugeza igihe pH agaciro kivanze kavanze ari alkaline, hanyuma ukongeramo gukuramo ester, ibivuyemo byogejwe kabiri hamwe na 30% ya sodium ya chloride, isabune yogejwe Nyuma yo kubura umwuma hamwe na sulfate ya anhydrous magnesium, kuyungurura munsi yumuvuduko ukabije, distillate ikusanyirizwa hamwe na 131 ℃ / 1330Pa, kandi distillate yabonetse nigicuruzwa 1,2- octanediol.
