Solubilities of triphenylphosphine in ethanol, 2-propanol, acetone, benzene, and toluene
The solubilities of triphenylphosphine in the organic solvents ethanol, 2-propanol, acetone, benzene, and toluene were measured by a gravimetrical method from (303.2 to 333.2) K. The logarithm of the solubility data was correlated against temperature with the average absolute error less than 2 %. The solubility of triphenylphosphine in ethanol was compared with the literature data and agreed with the literature data within 1.7 %. Although ethanol is often used for recrystallization of triphenylphosphine, the solubility of triphenylphosphine in acetone was higher compared with other solvents. Knowledge of the solubility data in the organic solvents is useful in the study of the crystallization of triphenylphosphine.
