Abstract

The published isothermal density data of aqueous monoisopropanolamine (MIPA) for different temperatures are converted into molar volumes as a function of composition. Tikhonov regularization is applied to obtain the derivatives of molar volume with respect to composition. These derivatives are used to compute the two partial molar volumes of the aqueous solution covering the entire composition range and for all the temperatures reported. A second application of Tikhonov regularization is then used to obtain the partial molar coefficients of the thermal expansion of the solution under constant pressure. This is followed by an examination of the second derivative of the partial molar volumes w..
