Solubility and mixing thermodynamic properties of (2,4,6-trimethylbenzoyl) diphenylphosphine oxide in pure and binary solvents

Abstract

The solubility of (2,4,6-trimethylbenzoyl) diphenylphosphine oxide (Lucirin TPO) in ten pure solvents and two binary solvent mixtures was measured from 273.15 K to 308.15 K by gravimetric method. The solubility of Lucirin TPO increased non-linearly with rising temperature in all the studied solvents. Furthermore, the solubility in mixed solvents presented a maximum-solubility effect. The modified Apelblat model, λh model, CNIBS/R-K model, NRTL model and Jouyban-Acree model were employed to correlate the experimental solubility data. The modified Apelblat model provided the best agreement in pure solvents, while the modified Apelblat model and CNIBS/R-K model gave better correlation results in binary solvent mixtures. Moreover, the thermodynamic properties of the mixing process, including the mixing Gibbs free energy, mixing enthalpy and mixing entropy were calculated from the solubility data using the NRTL model.
