摘　　要：由2，6－二氯甲苯经氨氧化法一步制备2，6－二氯苯腈，再经氟化、水解得到2，6－二氯苯甲酰胺的合成方法。三步的产率分别为85.8％、92．7％、96.2％，总收率达76．6％，该路线技术成熟可靠．指标优良．有利于促进我国苯甲酰脲农药的开发生产。2, 6 - Difluorobenzamide, an intermediate of benzoyl urea pesticides, is synthesized from 2, 6 - dichlorotoluene by ammoxidation, fluorination and hydrolysis in 85. 8 %, 92. 7%, 96.2% yield respectively and in 76. 6% total yield. This route is convenient and practical, having excellent economical index. It will promote the research and production of benzoyl urea pesticides in our country.
