-
Paragraph 0083; 0084; 0086; 0087, (2019/03/08)
The method for producing a polythiol compound includes reacting 2-mercaptoethanol having a water content of 3000 ppm or less on a mass basis, with epihalohydrin to obtain a halide represented by the formula (1), wherein X represents a halogen atom; and obtaining at least one polythiol compound selected from the group consisting of a polythiol compound represented by the formula (4), a polythiol compound represented by the formula (5), a polythiol compound represented by the formula (6), and a polythiol compound represented by the formula (7).
THIOL COMPOUND PRODUCTION METHOD AND NOVEL THIATING AGENT
-
Paragraph 0069, (2019/12/25)
PROBLEM TO BE SOLVED: To provide: a thiol compound production method which allows selective production of a thiol compound of interest, inhibits production of by-products ending up wastes, is excellent in production efficiency, and can reduce production costs; and a novel thiating agent used for the method. SOLUTION: The thiol compound production method comprises: a step 1 of preparing a thiuronium salt by reacting at least one compound represented by the general formula (1) defined by R-(X)m with a thiating agent comprising at least one compound selected from compounds represented by the general formula (2) in the figure; and a step 2 of hydrolyzing the thiuronium salt to prepare a compound represented by the general formula (3) defined by R-(SH)m.
