chlorempenthrin Chemical Properties,Uses,Production

Chemical Properties

Chlorempenthrin is a light yellow liquid or a light yellow to white solid with a reduced pressure boiling point of 128–130°C at 40 Pa. Its density is 1.12 g.cm–3 at 20°C. The refractive index of chlorempenthrin is 1.5037 at 25°C. It is easily soluble in organic solvents such as acetone, ethanol and benzene but insoluble in water.

Uses

Chlorempenthrin is used in the sanitary insecticidal compositions. It is also used in self heating Mosquito repellent.

Preparation

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%.

General Description

Chlorempenthrin, also known as 1-ethynyl-2-methylpent-2-enyl (RS)-2,2-dimethyl- 3-(2,2-dichlorovinyl) cyclopropanecarboxylate and 3-(2,2-dichlorovinyl)-2,2- dimethylcyclopropanecarboxylic acid-1-ethynyl-2-methylpenten-2-ol ester, is a derivative of 1-ethynyl-2-methyl penten-2-ol. Molecular formula: C17H22O2Cl2, molecular weight: 329.265.
