Xanthate

Xanthate

Xanthate usually refers to a salt with the formula ROCS2-M+ (R = alkyl; M+ = Na+, K+). The name xanthates is derived from Greek ξανθός, meaning “yellowish, golden”, and indeed most xanthate salts are yellow. These organosulfur compounds are important in two areas, the production of cellophane and related polymers from cellulose and secondly in mining for the extraction of certain ores. They are also versatile intermediates in organic synthesis. Xanthates also refer to esters of xanthic acid. These esters have the structure ROC(=S)SR'.
