Paragraph 0040; 0047-0048; 0049; 0056-0057; 0064-0065, (2020/05/08)
The invention discloses a method for preparing 2, 5-dimethylphenylacetyl chloride, and belongs to the field of pesticide intermediate synthesis. According to the method, p-xylene is used as an initialraw material, chloromethylation, cyaniding, hydrolysis and acylating chlorination are carried out, 2, 5-dimethylphenylacetyl chloride is obtained after continuous reaction without purification, the total yield of the four steps of reaction is 75%, and the product purity is greater than 99.0%. The method is simple in process and only needs to purify the final product and is low in operation cost,mild in reaction condition and high in yield and product purity and is very easy to realize industrial production.
