ABSTRACT
The vapor pressures of the pure components 3-aminopropylmethylamine (MAPA), 3-aminopropyldimethylamine (DMAPA) and N,N-diethyl 1,3-propanediamine (DEAPA) along with the binary mixtures (MAPA + water), (DMAPA + water) and (DEAPA + water) were measured by means of a static apparatus at temperatures between (273 and 363) K. The data were correlated with the Antoine equation. From these data, excess Gibbs functions (GE) were calculated for several constant temperatures, and fitted to a three parameters Redlich Kister equation using the Barker s method. Additionally, the NRTL and UNIQUAC models have been used for the correlation of the total pressure.
