Abstract

PURPOSE:To suppress decomposition in distillation and obtain neophyl halides in high yield of distillation and purification, by carrying out distillation and purification of the neophyl halides using a polyaminopolycarboxylic acid based chelate reagent as a decomposition inhibitor. CONSTITUTION:Neophyl halides expressed by formula I (R1 and R2 are H, halogen, lower alkyl or lower alkoxy; X is halogen) [e.g. 2-methyl-2-(3-chloro-4- ethoxyphenyl)propyl chloride] are purified. In the process, a polyaminopoly carboxylic acid based chelate reagent (e.g. ethylenediaminetetraacetic acid or transcyclohexanediaminetetraacetic acid) which is a decomposition inhibitor in an amount of preferably about 0.5-2% is added to carry out continuous or batch distillation at 150-230 deg.C under reduced pressure. The neophyl halides expressed by formula I are a raw material for compounds expressed by formula II which are insecticides and acaricides.
