Abstract
PURPOSE: To obtain the titled compound useful as a raw material for a high polymer compound, etc. in quantitiative yield industrially advantageously, by halogenating directly acrylonitrile with a halogenating agent in the presence of a specific catalyst in the absence of light in a liquid phase.
CONSTITUTION: Acrylonitrile is halogenated directly with a halogenating agent in the presence of a catalytic amount of a monohydrogen phosphate of an alkali metal or alkaline earth metal in the absence of light in a liquid phase, to give the titled compound.
EFFECT: Since this reaction is not a photo reaction, it neither require a specific reactor nor prepare any by-products. A recovered catalyst after using is reprocessed readily by treating it with a strong alkali and the catalyst is circulated for use without problems.
