Method for producing epoxy compound

摘要

To provide a method for producing an epoxy compound having fewer residual quaternary salt compound by removing the quaternary salt compound from an organic solution containing an epoxy compound and the quaternary salt compound.;A method for producing an epoxy compound comprising the following step 1, step 2, and step 3:
step 1: a step in which in a mixture liquid containing an olefin compound, an aqueous hydrogen peroxide solution, a quaternary salt compound, a heteropoly acid, and an organic solvent, the olefin compound is subjected to the oxidation reaction to obtain an organic solution (A) containing an epoxy compound,step 2: a step in which an aqueous inorganic alkali solution is allowed to contact with the organic solution (A) to obtain an organic solution (B) containing the epoxy compound, andstep 3: a step in which an acidic aqueous solution containing a polymer having at least one functional group selected from the group consisting of a carboxyl group and a sulfonic acid group is allowed to contact with the organic solution (B) to obtain an organic solution (C) containing the epoxy compound.
