FTIR Spectra of pure components and their binary liquid components (Binary mixtures of formamide with aniline, N-methyl aniline and N,N-dimethyl aniline)

Densities (ρ) speeds of sound (u) and viscosities (η) binary mixtures formamide (F) with aniline (A), N-methylaniline (NMA)and N,N-dimethylaniline (DMA), including those pure liquids, over the entire composition range were measured at temperatures (303.15, 308.15 313.15) K 0.1 MPa. Using experimental data, excess parameters (VE, ksE), deviation in viscosity (Δη), partial molar volumes, V¯m,1E V¯m,2E, isentropic compressibilities, K¯s,m,1E K¯s,m,2E components infinite dilution calculated. The VE results have been analysed terms Prigogine-Flory-Patterson theory. An analysis each three contributions viz. interactional, free volume P* to shows that effects are negative for all mixtures. FT-IR properties carried out study specific interaction, such as formation a hydrogen bond between unlike molecules liquid A good agreement is observed among spectroscopic properties.
