摘　　要：利用静态法测定了不同温度下单一碳四烃与吗啉二元体系的压力组成曲线，与纯碳四烃的饱和蒸汽压曲线比较，吗啉大大降低了碳四烃的蒸汽压，并加大了烷烃对烯烃的相对挥发度。另外，还测定了正丁烷对１－丁烯和顺－２－丁烯的相对挥发度。The P-X curves of C4 hydrocarbons dissolved in morpholine are determined at different temperatures by at static method. Compared with the saturated vapor pressure of pure C4 hydrocarbons, the experimental data show that morphoine increases the relative volativity of butane to butenes. Therefore, it is possible that butane and butenes are separated by an extrative distillaiton process using mopholine as extractant ln addition, the relative volatility data of n-butane, 1-butene and cis-2-butene in morpholine at various temperatures have been determined.
