Volumetric and viscometric studies of vitamin (B6)‎ in aqueous and acidic media at different temperatures

Abstract EN

Densities and viscosities of pyridoxine(B6) in aqueous and acidic solutions at 298.15- 313.15K have been measured.

By Masson equation the experimental values of densities were used to estimate some significant parameters, such as apparent molal volume(Φv), limiting apparent molal volume(Φv0 ) and slop Sv, and the viscosity data have been investigatevia JonesDole equation, and the derived parameters, Jones-Dole coefficient B, and Falkenhagen coefficient A.

The results were interpreted in term of solute-solute and solute –solvent interaction.

The difference of B coefficient with temperature (dB/dT), was also determined the positive values indicate that pyridoxine(B6)in aqueous and acidic solutions is structure making
