二嗪农(地亚农)是一种高效杀虫杀螨剂,其化学名称为0,0-二乙基-0-(2-异丙基-6-甲基嘧啶基-4)硫代磷酸酯,1952年首先由 H.Gysin 合成,以后瑞士汽巴-嘉基公司、日本化药公司等企业相继开发并投产.1987年世界生产能力为2.63万吨.在美国、日本、以色列、印度尼西亚、韩国、印度、德国共有七套装置,其中美国的年生产量近7000吨,日本的年生产量近6000吨。该产品在日、美、澳、苏的水稻、玉米、小麦及卫生上登记,50%乳油在我国棉花、小麦上登记.我国的农药科研单位也进行过二嗪农的合成研究,七十年代初,山东农药研究所和张店农药厂曾完成了小试和中试,但限于原料供应、产品质量、价格等原因未能投产。
Diazinon (Diazinon) is a highly effective insecticide and acaricide with the chemical name 0,0-diethyl-O- (2-isopropyl-6-methylpyrimidinyl-4) thio Phosphates, first synthesized by H. Gysin in 1952, and later developed and put into production in Switzerland Ciba-Geigy, Nippon Kayaku and other companies in 1987. The world production capacity of 26,300 tons in 1987. In the United States, Japan, Israel, Indonesia There are seven installations in South Korea, India and Germany. Among them, the United States has annual output of nearly 7,000 tons and Japan produces nearly 6,000 tons. The product is registered in rice, maize, wheat and sanitation in Japan, the United States, Australia and the Soviet Union, and 50% of the EC is registered in China’s cotton and wheat. The research on the synthesis of diazinon is also conducted in China’s pesticide research institutes. At first, Shandong Institute of Pesticide and Zhangdian Pesticide Factory had completed a small test and pilot, but limited to the supply of raw materials, product quality, price and other reasons failed to put into operation.
