Manufacturing Process. Xanthate salts are produced by the reaction of an alcohol with sodium or potassium hydroxide and carbon disulfide: ROH + CS2 + KOH → ROCS2K + H2O. The reaction involves the attack of the alkoxide salt. For example, sodium ethoxide gives sodium ethyl xanthate. Virtually any alcohol can be used in this reaction.
