Abstract

The solubility isotherms of N-isopropylacrylamide monomer (NIPAM) in supercritical carbon dioxide were obtained by the synthetic visual method in the temperature range of 304.8–353.0 K and the pressures range of 0.1–40.0 MPa, and the maximal solubility of NIPAM in CO₂ at these state parameters was determined. In addition, the region of crossover of isotherms P_mix = f(x) was detected, and the nature of this phenomenon was discussed. The predictive ability of the Chrastil model was assessed for this system.

n -异丙基丙烯酰胺在二氧化碳中的溶解度

用目测法获得了n -异丙基丙烯酰胺单体（NIPAM）在温度为304.8 ~ 353.0 K、压力为0.1 ~ 40.0 MPa条件下在超临界二氧化碳中的溶解度等温线，并确定了这些状态参数下NIPAM在CO2中的最大溶解度。此外，还发现了等温线Pmix = f(x)的交叉区域，并对这一现象的性质进行了讨论。对该系统的预测能力进行了评价。
