Chemical Reagent

Major component: Sodium diethyl dithiocarbamate
Molecular Formula: (C2H5)2NCSSNa · 3H2O

Structural Formula:


Description:
White or gale gray crystal, no pungent odour, freely soluble in water and decomposed into carbon disulfide and diethylamine etc. with acids.
Principal uses:
The collectivity of Ethyl Thiocarbamate is similar with xanthates and dithiophosphages. Ethyl Thiocarbamate displays strong collective power and rapid flotation, low dosage in comparison with xanthates and dithiophosphates. Because its collectivity for pyrites is weak, Ethyl Thiocarbamate exhibits excellent selectivity in flotation of sulfide ores. Ethyl Thiocarbamate also exhibits the better flotation results than xanthates and dithiophosphates in flotation of copper, lead, zinc, antimony and other polymetallic sulfides. It is also used in refining of metallurgical processes, and as a promoter in rubber industry.
