新的广泛的数据报告了二氧化碳在14种物理溶剂中的溶解度,并与工业上广泛使用的其他两种溶剂(selexol®和亚砜)进行了比较。溶解度数据用亨利定律常数表示,并在25°C, 40°C和60°C下使用高压灭菌器进行了测量。研究得出结论,聚乙二醇二甲基醚及其混合物是去除CO2的最佳溶剂。
New extensive data are reported for the solubility of carbon dioxide in fourteen physical solvents, and compared to two other solvents widely used in industry (selexol® and sulfolane). The solubility data are expressed by Henry's law constants and have been measured at 25 °C, 40 °C and 60 °C, using an Autoclave cell. The study concludes that polyethylene glycol dimethyl ethers, and mixtures of these solvents are the best solvents for CO2 removal.
