Ammonium thiocyanate

副标题

Name: Ammonium thiocyanate
Alias: ammonium thiocyanide
English name: Ammoniutn Thiocyanate
Molecular formula: NH4SCN
Molecular weight: 76.12
Physicochemical Properties: Colorless monoclinic flake or columnar crystals, lustrous. Relative density 1.306, melting point about 149 C, easy to tolerate in water, ethanol, methanol, pyridine and acetone, insoluble in chloroform, ethyl acetate, insoluble in water, endothermic reaction, when iron salt formed blood red iron thiocyanide, and did not react with ferrous salt. Under the action of sunlight, the solution is red, thiourea is formed at about 140 C, and is decomposed into chlorine, carbon disulfide and hydrogen sulfide at 170 C. Easy to deliquescence, should be sealed and preserved.
Purpose: To manufacture synthetic raw materials for domestic medicine, auxiliary raw materials for hydrogen peroxide, dyes, polymeric catalysts for organic synthesis, raw materials for cyanide, ferrocyanide and thiourea, as coagulant for paint printing in fabric printing and dyeing, color developer for steam printing and rust inhibitor for zinc primer, adhesives for rare metals, as well as analytical reagents and photographs.
Packaging: Double-layer laminated woven bag, plastic inner bag, weight 25 kg/bag.
