Crystallization and Solubility Studies

The following properties of a purified sample of benzaldehyde have been measured: vapour pressure (311 to 481 K); density of liquid (293 to 490 K); heat capacity of crystals and liquid (13 to 425 K); enthalpy of fusion; triple-point, normal boiling, and critical temperatures; and enthalpy of combustion in oxygen. From the measurements, the enthalpy of vaporization, the entropy (crystal, liquid, and ideal gas); and the enthalpy of formation (liquid and ideal gas) have been calculated. Thermodynamic functions (0 to 1000 K) of the ideal gas have been calculated from a vibrational assignment and molecular dimensions.
