Abstract

Ethylene glycol butyl ether and acetic acid as raw materials, cyclohexane as dehydrant, by direct esterification method, under p-toluene sulfonic acid catalyst, the catalytic synthesis of ethylene glycol butyl ether acetate(EGBEA). In the single factor experiment examines the usage of the influence of the reaction, and through the orthogonal experiment of catalyst, material ratio, reaction time is discussed such as the influence of factors on the reaction. Using infrared spectroscopy, the products were characterized. Results show that when the ethylene glycol butyl ether is 11.817 g, acetic acid is 7.806 g, P-toluene sulfonic acid catalyst is 3 %, cyclohexane as 23.340 g, Keep the return rate 2 ~3 d/s, speed 3~4 r/s, reflux temperature 80~95 . Constantly in the process of reaction 60 minutes (reaction zone was born into the water), atmospheric distillation cyclohexane, before the rectification products, collection of 191~193 fractions. Vested colorless transparent EGBEA, the yield is 98.81 %. The bullishness of chromatographic analysis is more than 99 % purity.
