    • PROBLEM TO BE SOLVED: To provide a method for producing high-quality triphenylmethyl mercaptan from triphenylmethyl chloride easily, also safely and in a high yield, and high-quality triphenylmethyl mercaptan to be obtained by this.
      SOLUTION: The method for producing triphenylmethyl mercaptan includes: mixing triphenylmethyl chloride and a lower alcohol to form triphenyl methanol; and then causing reaction with hydrogen sulfide wherein the carbon number of the lower alcohol is 1 to 3 and the lower alcohol is methanol. In the method, triphenylmethyl mercaptan has a content of 98% or higher by an LC method and also the residues of triphenylalcohol of 2% or lower.
