Abstract The continuous butyl acetate producing process includes the heated esterification reaction of glacial acetic acid and butyl alcohol in certain ratio in a normal pressure esterifying tower, rectification inside a rectifying tower and cooling in a cooling tower. The esterification temperature is 100-110 deg.c and water content in the esterifying tower is controlled in 5-15 %; the temperatuer in the rectifying tower is controlled in 135-150 deg.c and its pressure in 0.01-0.06 MPa; and the acidity of the coarse ester in the top of the esterifying tower is controlled in 0.1%. The production process has high stability, low cost, low power consumption, and is one continuous and sealed process with no product volatilization and less environmental pollution.
