Antimicrob. & Account Managers, For All of the selected models provided good representation of the experimental solubilities. Benzaldehyde definition is - a colorless nontoxic aromatic liquid C6H5CHO found in essential oils (as in peach kernels) and used in flavoring and perfumery, in pharmaceuticals, and in synthesis of dyes. Besides, it is sometimes called benzenecarboxaldehyde, phenylmethanal, or benzoic aldehyde. It is a colorless liquid aldehyde with a characteristic almond odor. The binary solid–liquid phase equilibrium for 4-(methylsulfonyl)benzaldehyde in methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, acetone, acetonitrile, toluene, and acetic acid were studied experimentally within the temperatures range from (283.15 to 318.15) K under 101.3 kPa by using a static equilibrium method. Benzaldehyde: The auto-ignition of benzaldehyde occurs at 192°C. The solubilities of 4-(methylsulfonyl)benzaldehyde in the binary mixed solvents acetonitrile + methanol, acetonitrile + ethanol and acetonitrile + isopropanol were determined experimentally using an isothermal dissolution equilibrium method within the temperature range from 283.15 to 318.15 K under atmospheric pressure.
