Paragraph 0065; 0066; 0067; 0068, (2017/01/26)
The invention relates to an acetate preparation method. The method comprises the following steps: carrying out a contact reaction of sec-butyl acetate and alcohol in the presence of an ester exchange catalyst under an ester exchange reaction condition, adding products obtained after the contact reaction into a separation tower, controlling the tower top temperature to separate unreacted sec-butyl acetate and sec-butyl alcohol generated after the reaction from the tower top, and carrying out normal-pressure or reduced-pressure flash evaporation to separate acetate generated after the reaction from a tower bottom fraction, wherein the alcohol is alcohol having a general formula of R(OH)n and/or polyol alkylether having at least one hydroxy group, R is a C5-C20 n-valence alkyl group, a C5-C20 n-valence alkenyl group, a C5-C12 n-valence cycloalkyl group or a C7-C20 n-valence aryl group, and n is an integer in a range of 1-5. The method has the advantages of high conversion rate of the alcohol as a reaction raw material, and high acetate selectivity.
