1,2-octanediol siv thiab synthesis txoj kev

Taw qhia:
1,2-octanediol yog cov kua xim tsis muaj xim lossis cov khoom dawb, thiab nws cov ntsiab lus kub (℃) nyob rau hauv 1330Pa tej yam kev mob yog 131-132 ℃.1,2-octanediol tuaj yeem sib xyaw nrog ntau yam tshuaj lom neeg hauv txhua qhov sib piv, thiab muaj cov qauv zoo sib xws.

Kev npaj:
Ntxiv formic acid thiab hydrogen peroxide rau lub reactor nruab nrog ib tug stirring thiab tus pas ntsuas kub thiab lub tank theem siab, pib stirring, thiab ces ntxiv 1-octene.Tom qab qhov sib ntxiv, cov tshuaj tiv thaiv sib tov yog khaws cia rau 100 feeb, thiab tom qab ntawd evaporated nyob rau hauv qhov txo qis Formic acid thiab dej, ces ntxiv sodium hydroxide tov nyob rau hauv stirring kom txog rau thaum pH tus nqi ntawm cov tshuaj tov yog alkaline, thiab ces ntxiv ester extraction, lub Lub resulting extract yog ntxuav ob zaug nrog 30% sodium chloride, ntxuav extract Tom qab lub cev qhuav dej nrog anhydrous magnesium sulfate, distillation nyob rau hauv lub siab txo, lub distillate yog sau nyob rau hauv tus mob ntawm 131 ℃ / 1330Pa, thiab tau distillate yog cov khoom 1,2- octanediol muaj.
