WebJan 30, 2024 · Azeotropes. An azeotrope is a mixture that exhibits the same concentration in the vapor phase and the liquid phase. This is in contrast to ideal solutions with one component typically more volatile than the other; this is how we use distillation to separate materials. If the mixture forms an azeotrope, the vapor and the liquid concentrations ... WebNov 1, 2024 · DCM is often used to separate water-containing azeotropes (Sazonova et al., 2015, Mcconvey et al., 2012), thus it has been here applied as heterogeneous entrainer.
