Additional information

Solid xanthates decompose exposed to moisture in air, releasing carbon disulfide(CAS# 75-15-0), an alcohol and alkali hydroxide.

Hydrolysis is a significant factor in determining the environmental fate of xanthates.

In neutral or mildly alkaline water solution, sodium ethyl xanthate decomposes to ethyl alcohol, carbon disulfide, sodium carbonate and sodium trihiocarbonate.
