摘要
采用等温法测定了15℃时NH4Cl-CO(NH2)2-H2O2-H2O四元体系及其子体系CO(NH2)2-H2O2-H2O和NH4Cl-CO(NH2)2-H2O的相平衡数据.依据所绘相图分析得知,在四元体系中氯化铵、过氧化氢和尿素不能形成新的加合物.15℃时CO(NH2)2-H2O2-H2O三元体系中合成过氧化尿素的适宜条件范围较宽,而NH4Cl在NH4Cl-CO(NH2)2-H2O2-H2O四元体系中对过氧化尿素析出没有盐析效应.
The phase equilibrium data of the quaternary NH4Cl-CO（NH2）2-H2O-H2O2 system and its subsidiary system CO （NH2）2-H2O2-H2O and NH4Cl-CO （NH2）2-H2O were measured at 15 ℃ by means of isotherm. According to the phase diagram analysis, it is found, that ammonium chloride, hydrogen peroxide and urea can not form adducts in this system, the suitable conditions of urea peroxide synthesized from ternary CO（NH2）2-HEO2-H2O are a broad range and ammonium chloride have no salting out effect on the formation of urea peroxide in the quaternary NH4Cl-CO（NH2）2-H2O-H2O2 system.
