Abstract

The invention discloses a preparation method and application of 3, 5, 5-trimethyl hexanoic acid, and belongs to the technical field of preparation of 3, 5, 5-trimethyl hexanoic acid. The preparation method of the 3, 5, 5-trimethyl hexanoic acid comprises the following steps: S1, carrying out a dehydration reaction on tert-butyl alcohol to prepare isobutene; in the tert-butyl alcohol, the mass content of n-propyl alcohol is less than 0.3%, the mass content of isopropyl alcohol is less than 0.3%, the mass content of n-butyl alcohol is less than 0.3%, and the mass content of isobutyl alcohol is less than 0.3%; s2, preparing diisobutylene from the isobutylene prepared in the step S1; s3, carrying out hydroformylation reaction on the diisobutylene prepared in the step S2 to prepare 3, 5, 5-trimethyl hexanal; and S4, carrying out oxidation reaction on the 3, 5, 5-trimethyl hexanal prepared in S3 to prepare the 3, 5, 5-trimethyl hexanoic acid. The 3, 5, 5-trimethyl hexanoic acid prepared by the method disclosed by the invention is high in purity.
