Paragraph 0051; 0052; 0053; 0054, (2020/11/05)
The invention discloses a preparation method of an xanthate compound. The method is characterized in that an xanthate and a chloride react at 0-60 DEG C in the presence of a phase transfer catalyst toprepare the xanthate compound with high purity and high yield. Compared with the existing method, the process for preparing xanthate compounds by phase transfer catalysis without solvent (self-solvent) is simple, the product purity is good, the yield is high, and the method is economic and environment-friendly and is suitable for industrial production.

An efficient and general preparation of S-(alkoxycarbonyl)-O-alkyldithiocarbonates is described.The method is based on the reaction of potassium O-alkylmonothiocarbonates with O-alkylchlorothiocarbonates in acetone-water (9:1) at 0 deg C.The yields are 91-100percent.

The thiolysis of S-ethoxycarbonyl O-ethyl dithiocarbonate (1) has been examined in order to study both its transesterification reaction and the reactivities of its carbonyl and thiocarbonyl groups.The two symmetrical pyrothiocarbonates (EtOCS)2S (4) and (EtOCO)2S (5) are produced by reactions of (1) with EtOCS2K (7) or EtOCOSK (8) in 95percent ethanol at 0 deg C; (4) was always the main product in the reaction with (7) whereas (5) was initially the main product in the reaction with (8).The reaction of (1) with BuOCS2K yielded first BuOCS2CSOEt and then BuOCS2CO2Et and (BuOCS)2S.These results indicate that the thiocarbonyl group of (1) is more reactive than the carbonyl one.
