Method for synthesizing trimethylacetic acid and 2,2,4,4-tetramethylvaleric acid through diisobutylene carbanyl group

The invention discloses a method for synthesizing trimethylacetic acid and 2,2,4,4-tetramethylvaleric acid through a diisobutylene carbanyl group, and belongs to the technical field of organic carboxylic acid synthesis. An oxo synthesis method is adopted, and the method for synthesizing trimethylacetic acid and 2,2,4,4-tetramethylvaleric acid through the diisobutylene carbanyl group comprises the following steps that 1, a carbonylation reaction is conducted, wherein diisobutylene, carbonic oxide and water serve as the raw materials, a sulfuric acid aqueous solution with the concentration ranging from 65% to 80% serves as a catalyst, pressurization is conducted under the condition of 20 DEG C to 30 DGE C for a reaction, and a mixture of pivalic acid sulfonate and 2,2,4,4-tetramethylvaleric acid sulfonate is obtained; 2, hydrolysis is conducted, wherein the obtained mixture of pivalic acid sulfonate and 2,2,4,4-tetramethylvaleric acid sulfonate in the first step is subjected to hydrolysis at 5 DEG C to 10 DEG C, standing is conducted for layering, an aqueous phase is subjected to extraction and concentration and then recycled, an organic phase is subjected to rectification, and trimethylacetic acid and 2,2,4,4-tetramethylvaleric acid are obtained. According to the method for synthesizing trimethylacetic acid and 2,2,4,4-tetramethylvaleric acid through the diisobutylene carbanyl group, diisobutylene is adopted to replace pure isobutylene in the prior art to react with sulfuric acid and carbonic oxide to produce trimethylacetic acid, and 2,2,4,4-tetramethylvaleric acid is generated simultaneously; the method is convenient and safe, and potential safety hazards are greatly reduced.
