LIQUID-VAPOR EQUILIBRIA IN BINARY-SYSTEMS CONTAINING MORPHOLINE

Experimental liquid-vapor equilibrium data obtained at 101.32 kPa in a recirculation still are presented for three binary systems containing morpholine (tetrahydro-1,4-oxazine) in mixtures with methanol, water, toluene respectively and compared with available literature data. In this order, thermodynamic analysis was carried out using the method gi ven by Kollar-Hunek et al. (1986) on all available and own data; therm odynamically consistent data were reduced to the parameters in the equ ations given by Wilson (1964), Renon and Prausnitz (NRTL, 1968) respec tively by Gothard (1985) using the version of the maximum likelihood p rocedure given by Panaitescu (1982) including statistical analysis and computation of the parameters of the confidence ellipses.
