| 摘 要： | 大范围内测定了ＣＯ２在Ｎ－甲基二乙醇胺（ＭＤＥＡ）－哌嗪（ＰＺ）水溶液中的溶解度，并建立了满足工程应用的热力学模型，模型平均偏差为９．７％。研究表明哌嗪在溶液中主要存在一级离解反庆，二级离解反应可以忽略。

| Abstract: | Solubility of CO 2 in aqueous mixtures of MDEA with PZ has been further measured and a thermodynamic model, which can be used for engineering calculation, is proposed with the average deviation of 9.7%. The study indicates that there exists a first order dissociation reaction for piperazine in the solution and the second order dissociation reaction can be neglected. |
