Ethylene Glycol Monoethyl Ether Acetate Ka 111-15-9
E fumanoa ke karabelo ea ethylene glycol monoethyl ether le acetic anhydride. Kopanya acetic anhydride le concentrated sulfuric acid. Ka mor'a ho futhumatsa ho 130 ° C, butle-butle eketsa ethylene glycol monoethyl ether dropwise. Mocheso oa karabelo o bolokoa ho 130-135 ° C. Phallo e ile ea eketsoa bakeng sa 1-2 h, 'me mocheso oa reflux e ne e le 140 °C. Ka mor'a ho pholile, fokotsa ka sodium carbonate ho pH = 7-8, 'me u omelle ka indasteri ea anhydrous potassium carbonate. The desiccant e ne e tlhotliloeng bakeng sa ho aroloa ho sa tloaelehang, 'me distillate pakeng tsa 150-160 ° C e ile ea bokelloa. Ho arohana ho etsoa hape, 'me karoloana ea 155.5-156.5 ° C e bokelloa e le sehlahisoa se felileng. E ka boela ea fumanoa ka catalyzing ethylene glycol monoethyl ether le acetic acid le concentrated sulfuric acid le refluxing ka benzene.
