Abbreviation:SN-9
CAS No:148-18-5
Ethyl thiocarbamate
Other name: Sodium diethyldithiocarbamate
MF(C2H5)2NCSSNa·3H2O
Physical
White or gale gray crystal, no pungent odour, freely soluble in water and decomposed into carbon disulfide and diethylamine etc. with acids.
Specification
Purity ≥94.0
Free alkalil ≤0.5
Application
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.
Packaging
50kg/bag.
Storage
Store in dry, cool and ventilated place in seal; keep away from fire source.
White or wind gray crystal, no pungent smell, easily soluble in water, decomposed with acid into carbon disulfide, diethylamine, etc. The collective properties of ethyl thiocarbamate are similar to those of xanthate and dithiophosphate. Compared with xanthate and sodium dithiophosphate, ethyl thiocarbamate has the advantages of strong collection capacity, fast flotation speed and less consumption. Ethyl thiocarbamate has weak collectivity to pyrite and shows good selectivity in flotation of sulfide ore. In the flotation of copper, lead, zinc, antimony and other polymetallic sulfides, ethyl thiocarbamate is superior to xanthate and sodium dithiophosphate. It is also used in the refining of metallurgical processes and as an accelerator in the rubber industry.
