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.
