Studying the structure of the vapor–liquid equilibrium diagram of the butyl propionate–propionic acid–butyl butyrate–butyric acid system

详细

This article deals with specific structural features of the vapor–liquid equilibrium diagram of the butyl propionate–propionic acid–butyl butyrate–butyric acid four-component system, which is of industrial importance and contains biazeotropic ester–acid constituents. The positions of some isomanifolds in the concentration tetrahedron and in its constituents are reported.
