2-,5-dimercapto-1,3,4-thiadiazole dilithium salt and its dihydrate and their manufacture

摘要

A dilithium salt dihydrate of 2,5-dimercapto-1,3,4-thiadiazole (DMc T) may be manufactured by the reaction of 2,5-dimercapto-1,3,4-thiadiazole with a lithiation agent in a solvent at 0-120 DEG C, wherein the mole ratio of lithium in the lithiation agent to DMc T is adjusted to 1.8-3.0. The dilithium salt and its dihydrate are useful inter alia in the manufacture of lithium batteries.
