Abstract

PURPOSE: To recover catalyst while preventing waste water load and environmental pollution through water-extraction of a liquid produced by the reaction between a benzonitrile group and a halide group with presence of a salt of organic quaternary NH4 and an alkali after divide into multiple stages.
