ABSTRACT

The mole fraction solubilities of bis(2,4,6-trimethylbenzoyl)phenylphosphine oxide (BPPO) in different organic solvents such as methanol, ethanol, ethyl acetate, cyclohexane, 2-propanol, acetonitrile, n-hexane, dichloromethane, dichloroethane, chloroform, benzene, and toluene were measured at a designated temperature of (295 to 345) K by the gravimetrical method. The solubilities of BPPO in dichloromethane, dichloroethane, chloroform, benzene, and toluene were all higher than 25 g*100 g 1 at 295.4 K. The mole fraction solubilities (x) of BPPO in methanol, ethanol, ethyl acetate, cyclohexane, 2-propanol, acetonitrile, and n-hexane were correlated as a function of temperature. Results showed that the calculated solubilities were in good agreement with the experimental solubility data.
