    production methodprocess of Thiourea powder

    • Absorb hydrogen sulfide with lime milk under negative pressure and cooling to produce calcium thiourea solution. React calcium thiourea with calcium cyanamide (lime nitrogen) at 1:5 molar ratio at 80℃ for 3h, then obtain thiourea solution, filtration, concentration, cooling and crystallization, shake filtration and drying, then obtain the finished product of Thiourea Raw Materials.In addition, the ammonium thiocyanate method and diazomethane method can be used to produce Thiourea Raw Materials.
    • Production method of the preparation method is to barium sulfide and sulfuric acid or hydrochloric acid reaction, hydrogen sulfide gas is absorbed by the negative pressure of the milk of lime to produce calcium hydrosulfide solution, and then react with calcium cyanamide, calcium hydrosulfide and calcium cyanamide molar ratio of 1:5, under constant stirring, the reaction temperature of (80 ± 5) ℃, the reaction time of 3h, filtered under negative pressure, can produce thiourea liquid, and then after evaporation, filtration, cooling, crystallization, the crystal thiourea, centrifugal dewatering and drying, can be obtained. Then after evaporation, filtration, cooling, crystallization, that is, crystal thiourea, centrifugal dehydration and drying that is, Thiourea powder. reaction equation such as: BaS + H2SO4 → BaSO4 ↓ + H2S ↑ 2H2S + Ca (OH) 2 → Ca (SH) 2 + 2H2O
    • Production method synthetic method with barium sulfide and hydrochloric acid (or sulfuric acid) reaction, with the milk of lime negative pressure absorption, and then reacted with lime nitrogen, after filtration, cooling crystallization, centrifugal separation, drying, to produce Thiourea CAS 62-56-6 .
