Based Technologies - Manufacture of Esfenvalerate
Introduction
Fervaleric acid [2-(4-chlorophenyl)-3-methylbutyric
acid] is resolved into S-2 (4-Chlorophenyl)-3-Methyl
butyric acid, which is converted into acid chloride
followed by reaction with m-phenoxy benzaldehyde and
sodium cyanide diastermic mixture. The product thus
obtained transform into a single active isomer esfenvalerate.
This can be implemented in existing synthetic pyrethroid
manufacturing unit
Applications
Esfenvalerate is a potent contact oral infested insecticide
with very broad range of activity, especially effective
against Coleoptera, Hemiphera, Lepidoptera and orthoptera
on cotton, fruits, vegetables and other crops.
