chlorempenthrin 化学特性,用途語,生産方法
使用
Chlorempenthrin is used in the sanitary insecticidal compositions. It is also used in self heating Mosquito repellent.
製造方法
2-Methyl-1-ethynyl-2-pentenol, pyridine and toluene were added to the reaction vessel,
and 3-(2,2-Dichlorovinyl)-2,2-dimethylcyclopropanecarbonyl chloride were added in a
dropwise manner under agitation. The reaction was carried out at a suitable temperature for 6 h. After reaction, the reaction solution was washed with water until neutral,
dried and then subjected to distillation under reduced pressure. Chlorempenthrin was collected from a fraction of 130–132°C (1mmHg). The yield of chlorempenthrin
was 86%.
