METHOD FOR PRODUCING CYCLIC PHENOL SULFIDE

摘要

PROBLEM TO BE SOLVED: To provide a method for efficiently producing a cyclic phenol sulfide with a polymerization number of 4, 6 or 8. SOLUTION: This method for producing the objective cyclic phenol sulfide comprises the steps of reacting a 4-substittued phenol with sulfur dichloride in a solvent to form a chain phenol sulfide dimer and reacting the dimer with a simple substance sulfur in the presence of an alkali metal hydroxide.
