根据公开文献中公布的结果，确定N2 O和CO2在水中的溶解度和扩散率作为温度的函数，并且在本工作中测量了新的数据。在各种温度下测量N2 O在几种烷醇胺（DEA、DIPA、DMMEA和DIPA）水溶液中的溶解度，并在宽范围的条件下进行关联。对于N2 O和烷醇胺在烷醇胺水溶液中的扩散系数，导出了修正的Stokes-Elnsteln关系式。还借助于“N2 O类比”，可以估计这些溶液中的CO2的扩散率。
Solubility and diffusivity of N20 and C02 In water were determined as a function of temperature from the results published In the open literature, and new data were measured in the present work. The solubility of N20 In several aqueous alkanolamine (DEA, DIPA, DMMEA, and DIPA) solutions at various temperatures was measured and correlated over a wide range of conditions. For both the diffusivity ofN20 and the alkanolamine In aqueous alkanolamine solutions a modified Stokes-Elnsteln relation was derived. With the aid also of the “N20 analogy” the diffusivity of C02 In these solutions can be estimated.
