A process for producing a halogen-containing phosphate ester, includes the steps of: (i) reacting a phosphorus halide selected from the group consisting of phosphorus oxyhalides and phosphorus pentahlides with a halogen-containing hydroxy compound to obtain a reaction mixture including a halogen-containing phosphate ester, (ii) purifying the halogen-containing phosphate ester by adding an aqueous medium selected from the group consisting of water, neutral aqueous solutions, acidic aqueous solutions and basic aqueous solutions to the reaction mixture to crystallize the halogen-containing phosphate ester, and (iii) distilling waste water from the purification step.
