A Study of Thermodynamic and Interaction Parameters of N-Formylmorpholine with Some Halobenzenes at 303.15, 308.15 and 313.15 K

Abstract

Excess molar volume $$ (V^{\text{E}} ) $$ and deviation in viscosity $$ (\Delta \eta ) $$ were calculated from measured values of density $$ (\rho ) $$ and viscosity $$ (\eta ) $$ for binary mixtures of N-formylmorpholine with some halobenzenes (fluorobenzene, chlorobenzene and bromobenzene) at temperatures (303.15–313.15) K and at atmospheric pressure. Using viscosity $$ (\eta ) $$ values, excess Gibbs energies of activation for viscous flow $$ (\Delta G^{{*{\text{E}}}} ) $$ and various viscosity correlating interaction parameters, including those of Dolezalek–Schulze $$ (D_{12} ) $$ , Grunberg–Nissan $$ (G_{12} ) $$ , Tamura–Kurata $$ (T_{12} ), $$ Katti–Chaudhri $$ (W_{\text{vis}} /RT) $$ and McAllister ( $$ M_{12} $$ and $$ M_{21} $$ ) have been calculated. The Kendall–Munroe relation, Bingham relation and Arrhenius–Eyring relation were calculated and the validity of these viscosity relations has been checked by comparison of calculated average percentage deviation between calculated values and experimental values. The results show negative values for excess molar volume $$ (V^{\text{E}} ) $$ , excess Gibbs energy of activation for viscous flow $$ (\Delta G^{{*{\text{E}}}} ) $$ and deviation in viscosity $$ (\Delta \eta ) $$ . These values show the presence of strong interaction between selected binary mixture components. The computed results were fitted with the Redlich–Kister polynomial equation.
