Study of the Refractive Parameters of N-Phenyl-2-Nitrobenzohydroxamic Acids in DMSO at Various Temperatures

Veenu Verma

Abstract: Densities (p) and refractive indices (n) for solutions of (0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09 and 0.1 M) N-Phenyl-2-nitrobenzohydroxamic acid (PNBHA) in dimethylsulphoxide (DMSO) have been measured at temperatures (298.15, 303.15, 308.15 and 313.15 K) under atmospheric pressure. Apparent molar volume (V f) and partial molar volume (V0 f) have been calculated from experimental values of densities. The refractive index data have been used to calculate molar refraction (RM), polarizibility (Α) and thermal co-efficient of the refractive index (dn/dt) for the hydroxamic acids. These parameters have been used to discuss the solute-solvent interactions.

Keywords: Density, refractive index and hydroxamic acid
