Sodium ethyl xanthate °C. It is the conjugate base of the unknown strong acid with p"K" of 1.6 and p"K" estimated as 12.4 for the conjugate base. Sodium ethyl xanthate easily adsorbs on the surface of solid sulfides. Xanthate are susceptible to hydrolysis and oxidation: These reactions require acidic conditions. Sodium ethyl xanthate can be identified through optical absorption peaks in the infrared (1179, 1160, 1115, 1085 cm) and ultraviolet (300 nm) ranges. There are at least six chemical detection methods: Sodium ethyl xanthate can also be quantified using gravimetry, by weighing the lead xanthate residue obtained after reacting SEX with 10% solution
Ethyl carbamate Ethyl carbamate Ethyl carbamate (also called urethane) is an organic compound with the formula CHCHOC(O)NH. It is an ester of carbamic acid. It is a white solid. Despite its name, it is not a component of polyurethanes. Because it is a carcinogen, it is little used, but has been detected in alcoholic beverages. It is produced industrially by heating urea and ethyl alcohol. It arise also by the action of ammonia on ethyl chloroformate. Ethyl carbamate has been used as an antineoplastic agent and for other medicinal purposes, but this application ended after it was discovered to be carcinogenic in
