Easily Soluble In Water
Ethyl sulfide nitrogen is a chemical substance whose molecular
formula is (C2H5)2NCSSNa·3H2O
| Chinese name | ethyl sulfur nitrogen |
| Molecular mass | 225.3 |
| Molecular formula | (C2H5)2NCSSNa·3H2O |
| Physical properties | white (or light yellow) loose crystal or powder |
| Abbreviation | SN-9 |
White powder, no obvious odor, m.p.87°C, easily soluble in water,
the aqueous solution is alkaline, it will gradually decompose with
water and carbon dioxide in the air, and will decompose into carbon
disulfide and diethylamine when exposed to acid.
Ethion is mainly used as a collector of Cu, Pb, Sb and other metal
sulfides. Its collection performance is similar to that of xanthate
and black medicine, but compared with xanthate and black medicine,
it has a strong collection capacity and floating Features such as
fast selection speed, dosage of medicament and high selectivity. It
can also be used for metal smelting and purification, and can also
be used as an accelerator in the rubber industry.
Preparation of ethyl sulfide
Dissolve diethanolamine in methanol, add carbon disulfide methanol
solution, drop 40% sodium hydroxide methanol solution, filter out
the precipitated crystals, wash with methanol 3 to 4 times, then
recrystallize with methanol and dry to obtain pure product Sodium
diethyldithiocarbamate.
