在催化剂中加入蒸馏水将催化剂破坏掉，再经过蒸发器蒸出粗乙酸乙酯。从下面

Distilled water is added to the catalyst to destroy the catalyst, and then the crude ethyl acetate is evaporated through the evaporator. The residual liquid of aluminum hydroxide is removed from below, and then the residual liquid is passed through a separator to further separate the aluminum hydroxide, and the liquid part will be returned to the evaporator.

The addition of distilled water to the catalyst destroys the catalyst and vaporizes the coarse ethyl acetate through the evaporator. Remove the aluminum hydroxide residue from below, and then further separate the aluminum hydroxide after passing through a separator, and the liquid part is returned to the evaporator.

The catalyst was destroyed by adding distilled water into the catalyst, and then the crude ethyl acetate was evaporated through evaporator. The residual aluminum hydroxide is removed from the following, and then the residual liquid is separated step by step after passing through a separator, and the liquid part will return to the evaporator.<br>
