Overview: Ammonium thiocyanate, also known as ammonium thiocyanate, ammonium thiocyanate, colorless lustrous monoclinic crystal system sheet or columnar crystal, chemical formula NH4SCN, molecular weight 76.12, at 92℃ for rhomboid crystal. The melting point is 147℃(decomposition at 170℃), the relative density is 1.3057, and the refractive index is 1.685. Soluble in water, endothermic reaction when dissolved in water, soluble in ethanol, alkali metal hydroxide, acetone, pyridine and liquid sulfur dioxide, insoluble in chloroform (trichloromethane). The solution turns red under sunlight. Blood red ferric thiocyanide is produced when it meets iron salt, which can be quantitatively determined by colorimetric comparison with the color of standard solution. Thiourea is formed when heated to about 140 ° C. At 176℃, it is decomposed into ammonia, carbon disulfide and hydrogen sulfide. It is easy to delix in the air and should be stored sealed and isolated from acids.

Method: Carbon disulfide and liquid ammonia in a pressurized reactor, the temperature is 30℃, reaction for 20 hours, or sulfur powder, sodium cyanide and ammonium chloride reaction with water, the temperature is controlled at about 110℃ can be obtained. Main uses: Used as polymerization catalyst for organic synthesis, printing and dyeing diffusion agent, pesticide herbicide, analytical reagent, such as determination of silver mercury and trace iron, and can also produce thiocyanate and thiocyanate complex salt. It has a certain solubility to silver halide, and its concentrated solution also has the ability to dissolve gelatin. It is used for photographic liquid medicine, gold toning of printing paper, printing of cotton fabrics, acid leaching of steel and so on.

Uses: 1. Used as polymerization catalyst for dyes and organic synthesis, separation of pesticides and defoliants, antibiotics, and raw materials for the manufacture of cyanide and thiourea. 2. Ammonium thiocyanate is an auxiliary raw material for hydrogen peroxide. Used as polymerization catalyst for dye and organic synthesis. Used for the separation of pesticides and antibiotics, analytical reagents, etc. It is also a raw material for the manufacture of cyanide, ferrocyanide and thiourea. Also used for zinc coating, printing and dyeing diffusion agent, plating additives. 3. Verification and determination of trace iron, determination of silver and mercury, polymerization catalyst, separation of antibiotics, analysis of pesticide content, water quality analysis, preparation of thiocyanate and standard solution.
