Zusammenfassung
A dynamic recirculation app. has been used to det. the isobaric phase equil. of binary 1-propoxy-2-propanol (PnP) mixts. with water and different alcs. (methanol, ethanol, 2-butanol and 1-hexanol). The systems exhibit both pos. and neg. deviations from Raoult's law. No azeotropic mixt. is found in any of the systems under investigation. The binary diagram of water/PnP shows the well-known ...

A dynamic recirculation app. has been used to det. the isobaric phase equil. of binary 1-propoxy-2-propanol (PnP) mixts. with water and different alcs. (methanol, ethanol, 2-butanol and 1-hexanol). The systems exhibit both pos. and neg. deviations from Raoult's law. No azeotropic mixt. is found in any of the systems under investigation. The binary diagram of water/PnP shows the well-known liq.-liq.-sepn. The exptl. results are correlated with the Wilson, NRTL and UNIQUAC model and also compared to the COSMO-RS predictive model and the modified UNIFAC group-contribution method. Addnl., the vapor pressure of PnP has been detd. exptl. up to 140 ° C as prerequisite for modeling of the data.
