Paragraph 0073; 0074; 0075, (2019/11/13)
The invention belongs to the technical field of fine chemical engineering, and particularly relates to a green synthetic method of kresoxim-methyl. The method comprises the following steps: carrying out nitrous nitrification by using 2-methylbenzyl cyanide as an initial raw material, carrying out methylation, carrying out hydrolytic methylation or hydrolytic esterification, carrying out bromination and carrying out an etherification reaction to obtain the high-content kresoxim-methyl. The method provided by the invention has a short reaction period, a high conversion rate, and excellent product quality, changes the defect that high-concentration hydrochloric acid gas is used for preparation in a traditional process, and has the advantages of simple operation steps, simple equipment, low energy consumption, a short period, high productivity and environmental protection.
