Sodium ethyl xanthate Sodium ethyl xanthate Sodium ethyl xanthate (SEX) is an organosulfur compound with the chemical formula CHCHOCSNa. It is a pale yellow powder, which is usually obtained as the dihydrate. Sodium ethyl xanthate is used in the mining industry as a flotation agent.

It is relatively stable in water at high pH if not heated. It rapidly hydrolyses at pH <9 at 25
