Ethylene Glycol Monoethyl Ether Acetate Ine 111-15-9
Inowanikwa kuburikidza nekuita kwe ethylene glycol monoethyl ether uye acetic anhydride. Sanganisa acetic anhydride ne concentrated sulfuric acid. Mushure mekudziya kusvika 130°C, wedzera zvishoma nezvishoma ethylene glycol monoethyl ether dropwise. Tembiricha ye reaction inochengetwa pa 130-135°C. Kuyerera kwakawedzerwa kweawa 1-2, uye tembiricha ye reflux yaive 140°C. Mushure mekutonhora, gadzirisa ne sodium carbonate kusvika pH=7-8, wobva waomesa ne industrial anhydrous potassium carbonate. Desiccant yakaseferwa kuti iparadzwe, uye distillate iri pakati pe 150-160°C yakaunganidzwa. Kupatsanurwa kunoitwa zvakare, uye fraction iri pa 155.5-156.5°C inounganidzwa sechigadzirwa chapera. Inogonawo kuwanikwa ne catalyzing ethylene glycol monoethyl ether uye acetic acid ne concentrated sulfuric acid uye refluxing mu benzene.
