Abstract

The solubility of organotin compounds under inert atmosphere plays a significant role in homogeneous catalysis process; however, no such study has been reported. The solubilities of dimethyltin dichloride (1), stannous chloride (2), β-diketiminato ligand LH (3) (L = HC(CMeNAr)₂, Ar = 2,6-Et₂C₆H₃), and tin (II) compound [LSnCl] (4) in six organic solvents were measured using a static analytic method from 268.15 K to 313.15 K under a purified nitrogen atmosphere to select the optimum solvent for a homogeneous reaction and recrystallization. The difference in solubility can be attributed to molecular structure, coordination bonding, and molecular polarity. Six commonly used thermodynamic models were used to correlate the experimental solubility data. Some models show a great correlation with a low value of average absolute deviation (AAD). In addition, the solubility parameter of solute, partial molar excess enthalpies at infinite dilution, and thermodynamic properties were calculated to study the dissolution behavior in more depth.
