Vapor pressures of pure and aqueous diethylenetriamine (DETA) and dipropylenetriamine (DPTA) were measured by means of a static apparatus at temperatures between (283 and 363) K. The data were correlated with the Antoine equation and fitted to Redlich-Kister equation using Barker's method. Additionally, the NRTL, UNIQUAC models were used to correlate total pressures.
