Ethylene Glycol Monoethyl Ether Acetate Nrog 111-15-9
Tau txais los ntawm cov tshuaj tiv thaiv ntawm ethylene glycol monoethyl ether thiab acetic anhydride. Sib tov acetic anhydride thiab concentrated sulfuric acid. Tom qab cua sov rau 130 ° C, maj mam ntxiv ethylene glycol monoethyl ether dropwise. Cov tshuaj tiv thaiv kub yog khaws cia ntawm 130-135 ° C. Cov dej ntws tau ntxiv rau 1-2 teev, thiab qhov kub ntawm reflux yog 140 ° C. Tom qab txias, neutralize nrog sodium carbonate rau pH = 7-8, thiab tom qab ntawd qhuav nrog kev lag luam anhydrous potassium carbonate. Cov desiccant tau lim tawm rau crude fractionation, thiab cov distillate ntawm 150-160 ° C tau sau. Fractionation yog rov ua dua, thiab cov feem ntawm 155.5-156.5 ° C yog sau ua cov khoom tiav. Nws tseem tuaj yeem tau txais los ntawm kev ua kom ethylene glycol monoethyl ether thiab acetic acid nrog concentrated sulfuric acid thiab refluxing hauv benzene.
