Xanthate Wikipedia

Xanthate usually refers to a salt with the formula ROCS − 2 M R alkyl M Na K thus O esters of dithiocarbonate The name xanthates is derived from Greek ξανθός xanthos meaning yellowish golden and indeed most xanthate salts are yellow They were discovered and named in 1823 by Danish chemist William Christopher Zeise These organosulfur compounds are important in
