Solubilities of 1,3,2-Dioxaphosphorinane-2-methanol-alpha,5,5-trimethyl-alpha-phenyl-2-o xide in Selected Solvents between 278.15 K and 343.15 K
The mole fraction solubilities of 1,3)2-dioxaphosphoririane-2-methanol-alpha,5,5-trirnethyl-alpha-phenyl-2-oxide in different-Organic solvents inducting acetonitrile, acetone; ethyl acetate, 1,2,dichloroethane, Methanol, ethanol, and chloroform were measured at a designated temperature range of (278.15 to 343.15) K and at atmospheric pressure by the gravimetrical method. The compound's structure and thermal stability were characterized by infrared, spectroscopy, nuclear magnetic resonante (H-1 NMR and(31)P NMR), mass Spectroscopy, elemental analysis, and thermogravimetric analysis. The mole fraction solubilities of 1,3,2-dioxaphosphorinane-2-methanol-alpha,5,5-trimethyl-alpha-phenyl-2-oxide in the above-mentioned organic solvents were correlated as the Apelblat equation, and the calculated values with equations showed good consistency with the experimental values. The root-mean-square deviation was less than 0.010 % and the average relative error Was less than 0.11 % in all the experiments.
