Additional information

The hydrolysis of xanthate in aqueous solution at room temperature is characterized by the following reaction:

6ROC(S)SNa + 3H2O = 6ROH + 2NaSC(S)SNa + Na2CO3+ 3CS2

Further hydrolysis of the CS2gives H2S and CO2and the trithiocarbonate hydrolysis produces H2S and sodium carbonate
