摘要：近年来，为解决碳酸丙烯酯（Propylene Carbonate简称丙碳）脱除 C风工艺中出现的脱碳净化度低、溶剂循环量大、设备腐蚀严重等问题而相继开发了多种改型丙碳复合溶剂，其中作者等人研制的由丙碳和适量的叔胺（MDEA）、水构成的混合溶剂，不仅脱碳性能明显优于丙碳，而且有效地解决了设备腐蚀问题。本文研究了CO。在此混合溶剂中的溶解度与温度和压力的关系。
The solubility of CO2 in a mixed solvent of propylene carbonate (P.C.) with methyldiethanolamine (MDEA) and water was measured at CO2 partial pressure of one atm within the temperature range of 10- 35℃ and at 25℃ over a wide range of CO2 partial pressures. The effect of the miscibih'ty of P.C. and water in the mixed solvent on the solubility of CO2 was investigated. As a result, immiscible mixed solvent shows significant improvement in absorption of CO2,which can be explained by the chemical equilibrium theory. Appropriate compounding of mixed solvents was determind.
