y orthogonal experiment, the stirring time, excess quantity of alkali andvolme ratio of ester and alkaline solution were investigated in neutralization of acetic acidcontaining in industrial n-butyl acetate. Furthermore, the processing conditions of refining for industrial n-butyl acetate was optimized in sieve--plate distillation column. It isnecessary for industrial prodllction of n-butyl acetate with the continuous catalytic reacting distillation technique.
