Improvements in the experimentation and the representation of thermodynamic properties (iso-p VLE and y) of alkyl propanoate+alkane binaries

<p>[EN]This paper presents the experimental measurements of isobaric vapor−liquid equilibria (iso-p VLE) and excess volumes (vE) at several temperatures in the interval (288.15 to 328.15) K for six binary systems composed of two alkyl (methyl, ethyl) propanoates and three odd carbon alkanes (C5 to C9). The mixing processes were expansive, vE > 0, with (δvE/δT)p > 0, and endothermic. The installation used to measure the iso-p VLE was improved by controlling three of the variables involved in the experimentation with a PC.</p>
