4-Chlorobenzyl cyanide Chemical Properties,Uses,Production
Chemical Properties
clear colorless to yellowish liquid after melting. Soluble in acetone and ethanol.
Uses
4-Chlorobenzyl cyanide is an intermediate for the preparation of 3-methyl-2-(4-chlorophenyl)butyric acid, which can be used to prepare pyrethroid insecticides such as fenvalerate and deltamethrin, and can be used in medicine Industrial preparation of pyrimethamine.
Definition
ChEBI: 4-Chlorobenzyl cyanide is a nitrile that is acetonitrile in which one of the hydrogens has been replaced by a p-chlorophenyl group. It is a member of monochlorobenzenes and a nitrile. It derives from an acetonitrile.
Preparation
4-Chlorobenzyl cyanide is obtained by the reaction of 4-Chlorobenzyl chloride with sodium cyanide. Add 4-Chlorobenzyl chloride and Benzyldodecyldimethylammonium bromide into the reaction pot, heat to 100°C, slowly add sodium cyanide aqueous solution, and react at 100-104°C for 5h (add sodium cyanide for 3h, keep warm for 2h). Then add water to dissolve sodium chloride, and separate the water layer to obtain the crude benzyl chloride cyanide, which is distilled under reduced pressure to collect 160 (2.66kPa) fractions to obtain the finished product of 4-Chlorobenzyl cyanide. The yield is above 81%.
