Butanol water azeotrope
WebIn industry the butanol-water mixture is separated with this technique. At the previous case the binary system forms already a heterogeneous azeotrope. The other application of the heteroazeotropic distillation is the separation of a binary system (A-B) forming a homogeneous azeotrope. WebIn the absence of CO2, more hydrophobic materials such as ZIF-8, ZIF-855-7145, ZIF-870-9030 and ZIF-71 are found to be excellent candidates with butanol/water selectivities > …

WebIt is observed that water forms a heterogeneous azeotrope with isobutyl acetate and a 2-phase region is present in the diagram. The water - isobutyl acetate azeotrope is an unstable node, while the acetic acid is a stable node [4].
