Abstract
PURPOSE: To improve the separation state greatly and increase the removal rate of a metal halide-remarkably, by mixing a chelating agent with an organic compound containing the metal halide in washing the compound with water, and separating the mixture into an oil and an aqueous layers to remove the metal halide.
CONSTITUTION: A metal halide to be contained in an organic compound as a catalyst or by-product is washed with water and removed. A chelating agent, e.g. a polyphosphate, is added to the organic compound as a removing assistant and mixed, and then the mixture is separated into an oil layer consisting of the organic compound and an aqueous layer. The chelating agent is used in such an amount as to make the pH of the waste water in washing the organic compound with water in the range of 3W9.
