| 摘 要： | 采用改进的Rose釜，在磁感应强度分别为0．165T、0．310T和0．515T的磁场作用下，对乙酸-水二元体系气液相平衡进行了研究．结果表明：磁场对体系的气液相平衡产生了影响，能提高体系的平衡常数，有利于体系的分离．同时，将缔合理论引入乙酸的相平衡计算中，选用Wilson和NRTL方程对气液相平衡数据进行了关联，并提出了磁场对乙酸-水体系气液相平衡的影响因子．

| Abstract: | The vapor-liquid equilibrium(VLE) of acetic acid-water system was studied under the different magnetic induction intensities which were 0.165 T,0.310 T and 0.515 T by using an improved Rose equilibrium cell.The results show that the magnetic field has a positive effect on the VLE of system,namely the magnetic field could improve the equilibrium constant and accelerate the separation of acetic acid-water system.The associating theory was also introduced to the calculation of acetic acid phase equilibrium,Wilson and NRTL equations were used to correlate the VLE data,the factor of magnetic field on the VLE of acetic acid-water system was also presented. |
