Introduction of Iso-butyl Acetate Manufacturing Process

Today we explain the Iso-butyl Acetate Manufacturing Process.

First,the acetic acid, isobutanol, cyclohexane, and catalyst are added to the esterification reactor in proportion, the stirring is started, and the temperature is slowly increased by jacketed steam, the esterification is continued for 1 hour, and the water and the azeotrope are continuously distilled. After the condenser is condensed, it enters the separator, the upper oil layer returns to the esterification reactor, and the lower water layer is discarded. The resulting reactants were transferred to storage tanks, the resulting reactants were cooled, the reaction liquids in the storage tanks were filtered and transferred to a neutralization scrubber, neutralized to a pH of 7.0 with a 5% strength sodium carbonate solution, and stirred half Hours, after standing, stratified and distilled, the crude ester was washed again with 20-30 water to obtain the initial product. After washing with water, dehydration was conducted under reduced pressure to obtain an ester. The entire process includes esterification, filtration, atmospheric distillation, neutralization, water washing, dehydration, and vacuum distillation.
