Ethylene Glycol Monoethyl Ether Acetate Pẹlu 111-15-9
Ti gba nipasẹ esi ti ethylene glycol monoethyl ether ati acetic anhydride. Dapọ anhydride acetic ati sulfuric acid ogidi. Lẹhin alapapo si 130 ° C, laiyara fi ethylene glycol monoethyl ether dropwise. Awọn iwọn otutu ifaseyin ti wa ni itọju ni 130-135 ° C. A fi kun sisan naa fun wakati 1-2, ati iwọn otutu reflux jẹ 140 °C. Lẹhin itutu agbaiye, yomi pẹlu kaboneti iṣuu soda si pH = 7-8, ati lẹhinna gbẹ pẹlu carbonate potasiomu anhydrous ile-iṣẹ. A fi iyọti kuro fun ida robi, ati pe distillate laarin 150-160°C ni a gba. Iyatọ ti tun ṣe lẹẹkansi, ati ida ni 155.5-156.5°C ni a gba bi ọja ti o pari. O tun le gba nipa gbigbe ethylene glycol monoethyl ether ati acetic acid pẹlu sulfuric acid ogidi ati refluxing ni benzene.
