Paragraph 0064; 0066; 0069, (2019/07/11)
The invention provides a method for preparing a N,N-Dimethylaniline compound through alkylation of alkyl tosylate, and belongs to the technical field of organic synthesis. According to the method, paratoluensulfonyl chloride and fatty alcohol serve as raw materials, pyridine serves as an acid-binding agent, and the alkyl tosylate is generated; the alkyl tosylate as an alkylation reagent and an aniline compound are alkylated under the alkaline condition to obtain the N,N-Dimethylaniline compound. The method is implemented at normal pressure, the operation is simple, no waste acid is generated,the yield and the purity are high, and the method is suitable for industrial and scaled production.
