烯啶虫胺是一类重要的烟碱类杀虫剂中的新品种,具有高效、广谱、低毒、耐抗性等特点,在世界范围内得到了广泛的应用,是重要的粮食作物、经济作物等多种虫害的优良防治用药。对于国内现有的杀虫剂难以防除的一些虫害,特别是蚜虫、叶蝉、半翅目害虫、水稻飞虱等,显示了卓越的活性,且防治费用低廉。烯啶虫胺低毒和对靶标虫害的特效作用也在兽药方面得到了广泛应用。在世界范围内(包括中国在内)得到了的应用,前景广阔。
1、1-二氯乙烯与盐酸、硝酸反应生成1、1、1-三氯-2-硝基乙烷,结束后需要加碱水中和,消除一分子氯化氢,生成1,1-二氯-2-硝基乙烯中间体,
反应生成1、1、1-三氯-2-硝基乙烷的收率仅能达到68%~80%
浩瀚色谱(山东)应用技术开发有限公司,研发气相色谱法测定1,1,1-三氯-2-硝基乙烷的含量,面积归一法定量,结果满意。

Fenpropathrin is an important new variety of nicotine insecticides, characterized by high efficiency, broad-spectrum, low toxicity, and resistance. It has been widely used worldwide and is an excellent control drug for various pests such as important food crops and cash crops. For some pests that are difficult to control with existing insecticides in China, especially aphids, leafhoppers, hemiptera pests, rice planthoppers, etc., they have shown excellent activity and low control costs. The low toxicity and specific effects on target pests of enacloprid have also been widely used in veterinary medicine. It has been applied worldwide (including China) and has broad prospects.
1. 1-Dichloroethylene reacts with hydrochloric acid and nitric acid to produce 1,1,1-trichloro-2-nitroethane. After completion, alkaline water needs to be added to eliminate one molecule of hydrogen chloride and generate an intermediate of 1,1-dichloro-2-nitroethylene,
The yield of 1,1,1-trichloro-2-nitroethane generated by the reaction can only reach 68% to 80%
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a gas chromatography method to determine the content of 1,1,1-trichloro-2-nitroethane, and the area normalization method has been used for quantification, with satisfactory results.
