Abstract:
1. A method for preparing 3,3-dimethylbutyraldehyde, the method comprising: 1) providing a t-butyl chloride and vinyl acetate as raw materials, conducting catalytic reaction between the t-butyl chloride and vinyl acetate to yield 1-chloro-3,3-dimethyl butyl acetate in the presence of a catalyst, wherein, a weight ratio of the t-butyl chloride to vinyl acetate is 1:0.84-0.93; and 2) controlling a temperature at between 100 and 110° C. for conducting hydrolytic disproportionation of 1-chloro-3,3-dimethyl butyl acetate in the presence of the catalyst to yield a mixture comprising 3,3-dimethylbutyraldehyde; and
