三聚甲醛精制过程开发与研究(Ⅰ)三聚甲醛——甲醛.水——溶剂(S_1,S_2)拟三元液——液平衡数据的关联

Correlation of Liquid-Liquid Equilibrium Data for the Mimicry Ternary Systems of Trioxan-Formaldehyde·Water-Solvent(S_1,S_2)

对常压下测定的45℃三聚甲醛——甲醛·水——溶剂(S_1,S_2)拟三元液——液相平衡数据用NRTL 方程和经验式进行了关联,关联结果表明,两种方法的拟合精度令人满意,均可用于工程设计。

The LLE data for the mimicry ternary systems of trioxan-formal-dehyde,water-solvent (S_1,S_2) at 45℃ determined at atmospheric pressureare correlated by NRTL equation and empirical method.The results show theequilibrium data are satisfactorily correlated by the two methods,and bothof them can be applied to project designs.
