    Production methodprocess of Thiourea powder

    • Absorb hydrogen sulfide with milk of lime under negative pressure and cooling to produce calcium thiourea solution. Calcium hydrosulfide and calcium cyanamide (lime nitrogen) according to the 1:5 molar ratio, at 80 ℃ about 3h reaction, that is, the thiourea solution, filtration, concentration, cooling crystallization, dumping filtration and drying, to get the finished product Thiourea powder . In addition, Thiourea powder can also be produced by ammonium thiocyanate method and diazomethane method.
    • The preparation method is to react with barium sulfide and sulfuric acid or hydrochloric acid, hydrogen sulfide gas is absorbed by the negative pressure of the milk of lime to obtain calcium hydrosulfide solution, and then reacted with calcium cyanamide, calcium hydrosulfide and calcium cyanamide molar ratio of 1:5, under constant stirring, the reaction temperature is (80 ± 5)℃, the reaction time of 3h, filtered under negative pressure, can generate thiourea liquid, and then evaporation, filtration, cooling, crystallization, that is, the crystal After evaporation, filtration, cooling and crystallization, the crystalline thiourea is obtained, and centrifugal dehydration and drying is obtained as Thiourea Raw Materials.
    • Synthesis method with barium sulfide and hydrochloric acid (or sulfuric acid) reaction, with the milk of lime under negative pressure absorption, and then reacted with lime nitrogen, after filtration, cooling crystallization, centrifugal separation, drying, the production of Thiourea CAS 62-56-6
