浙江省温州农药厂继7月17日由省科委委托石化厅组织专家对该厂500t/a二嗪磷工业化试验研究进行技术鉴定并顺利获得通过后,又于8月26日举行了新建成的3000t/a二嗪磷生产装置开工典礼。二嗪磷即地亚农,由瑞士汽巴——嘉基公司于1956年合成,是一个广谱、高效、中低毒有机磷杀虫杀螨剂,目有仍是世界上大吨位有机磷农药品种之一,我国自“五五计划”开始就将该品种列入国家攻关和发展的农药品种,七十年代末国内有关农药科研单位陆续开展二嗪磷的小试和中试,但终因开发难度大,关键起始原料异丁腈无法突破,使二嗪磷的工业化生产无法实现,二嗪磷的开发被迫搁置下来。温州农药厂于
After Wenzhou Pesticide Factory of Zhejiang Province was entrusted by the provincial science and technology commission to organize an expert of the petrochemical department on July 17 to carry out the technical appraisal of the industrial trial of 500t/a diazide phosphor, and passed the approval, it was held on August 26th. 3000t/a Diazine Phosphorus Production Plant Commencement Ceremony. Diazimphosphonium, namely diazophos, was synthesized by Swiss Ciba-Jiaji Company in 1956. It is a broad-spectrum, high-efficiency, low-tolerant organophosphorus pesticide and acaricide. It is still the world’s largest tonnage organic phosphorus. One of the pesticide species, China began to include this species in the national research and development of pesticide species since the beginning of the “Five-Five-Year Plan,” and at the end of the 1970s domestic pesticide research institutes began trials and pilot trials of diazinon. However, due to the difficulty of development, the key starting material isobutyronitrile could not be broken, making the industrial production of diazinon impossible, and the development of diazinon was forcibly put on hold.
