1,2-octanediol kushandiswa uye synthesis nzira

Nhanganyaya:
1,2-octanediol imvura isina ruvara kana chena yakasimba, uye nzvimbo yayo yekuvira (℃) pasi pe1330Pa mamiriro i131-132 ℃.1,2-octanediol inogona kusanganiswa nemhando dzakasiyana-siyana dzemakemikari mune chero chiyero, uye ine yakanaka yekugadzira kuenderana.

Kugadzirira:
Wedzera formic acid nehydrogen peroxide kune reactor ine inomutsa uye thermometer uye tangi yepamusoro-soro, tanga kubvongodza, uye wobva wawedzera 1-octene.Mushure mekuwedzera, mhinduro yemusanganiswa inochengetwa kwemaminetsi e100, uye yobva yanyungudutswa pasi pekumanikidzwa kwakaderedzwa Formic acid nemvura, wobva wawedzera sodium hydroxide solution pasi pekukurudzira kusvika pH kukosha kwemusanganiswa mhinduro iri alkaline, wobva wawedzera ester extraction, the mhedzisiro inobuda inoshambidzwa kaviri ne30% sodium chloride, iyo yakashambidzwa yakabudiswa Mushure mekupera mvura neanhydrous magnesium sulfate, distillation pasi pekumanikidzwa kwakaderedzwa, iyo distillate inounganidzwa pasi pemamiriro e131 ℃/1330Pa, uye yakawanikwa distillate ndicho chigadzirwa 1,2- octanediol.
