The results suggest that HOV-cooling effects as well as aromatic species enrichment … WebOct 4, 2012 · This Demonstration illustrates how the addition of an extraneous component, called an entrainer, can facilitate the separation. The entrainer alters the relative volatilities of the components and thereby "breaks" the azeotrope. Homogeneous azeotropic distillation generally uses a heavy entrainer, which does not introduce new azeotropes. WebOct 31, 2014 · A methanol/MMA azeotrope is broken or avoided by a method comprising the steps of (1) raising the pressure within a first vessel, e.g., a distillation column, that contains a methanol/MMA azeotrope, (2) collecting the azeotrope as a liquid, and then in a second, separate vessel, e.g., another distillation column, (3) raising the pressure … like tom yum soup crossword
