METHOD FOR PRODUCING SULFUR-CONTAINING ACRYLIC COMPOUND

摘要

PROBLEM TO BE SOLVED: To provide a method for producing sulfur-containing acrylic compounds having a high refractive index and not containing finely divided solid particles. SOLUTION: Sediments of impurities precipitated from a mixed solution where sulfur-containing crude acrylic compounds are dissolved in a mixture of a solvent with a nonsolvent are removed, and then the solvent and the nonsolvent are distilled out and the obtained sulfur-containing acrylic compounds are processed by filtration.
