The preparation of high purity sodium cyanate by liquid-solid chemical reaction method 液固化学反应法制备高纯度氰酸钠
Hydantoin was synthesized from glycine and sodium cyanate, which was condensed with benzaldehyde to give monohydrated sodium phenylpyruvate in 67.0% of overall yield after alkaline hydrolysis. 由甘氨酸和氰酸钠反应合成海因,然后与苯甲醛缩合,经碱水解得到一水合苯丙酮酸钠,总收率为67.0%。
Sodium cyanate was prepared from reactants& urea and anhydrous sodium carbonate through liquid-solid chemical reaction method, in the solvent of N, N-dimethlformamide ( DMF). 使用液固化学反应法,以尿素和无水碳酸钠为原料,在N,N-二甲基甲酰胺(DMF)溶剂的反应介质中,制备了氰酸钠产品。
