2,2-二甲氧基丙烷生产中有关体系加压下共沸点的研究

Study on Binary Azeotropic Systems at Elevated Pressures Concerning Synthesis of 2,2-Dimethoxypropane

测定了2,2-二甲氧基丙烷与甲醇、丙酮的二元体系在常压及加压条件下的共沸点数据,并对数据进行了关联。由关联结果可知,其共沸组成与共沸温度、压力的对数与共沸温度的倒数均呈良好的线性关系,计算结果与实验值符合良好。

The binary azeotropic data of 2,2-dimethoxypropane (1) + methanol (2),and + acetone (3) systems were determined under atmospheric and enhanced pressures.Experimental data were well correlated by a set of empirical equations.Azeotropic composition versus azeotropic temperature,and logarithm of system pressure versus reciprocal of azeotropic temperature were both distinctly linear.The calculated values were in good agreement with the experimental value.
