Solubilities of Bis(2,4,6-trimethylbenzoyl)phenylphosphine Oxide in Different Organic Solvents at Several Temperatures

摘要

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, H-hexane, dichloro-methane, 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.
