YieldReaction ConditionsOperation in experiment
86% at 230 - 260℃; for 2.00 h; Inert atmosphere A solution of trimellitic anhydride (1.0 mol)192 g was mixed with ethylene glycol (0.55 mol) of 34 g,Nitrogen emptying. In nitrogen holdContinued protection to a temperature of 230-240 ° C,This time will continue to have water distillate,Close to the theoretical amount of water (18 grams) after the distillation,Vacuum 10-15mmHg down to 260 for 2 hours, cooling,Refined with 900-1200 grams of acetone,The intermediate trimellitic anhydride ethylene glycol ester, white powder 176 grams, the yield of 86percent. The intermediate was hydrolyzed with a 5percent aqueous solution of sodium hydroxide,Dilute hydrochloric acid to pH = 1-3,Dried to the final product trimellitic acidEthylene glycol esters,White powder 211.8 g, yield 95percent.
