Abstract
A topological thermodynamic analysis was performed for a butanol–toluene mixture produced as a waste in the industry of paint–and–lacquer materials. Liquid–liquid equilibrium was experimentally studied in the system ethanol–toluene–chlorobenzene–water. Main pathways for separating a butanol–toluene mixture have been synthesized as flow graphs. A rectification analysis was performed for the system under study. Choosing a separating agent (benzene) has been performed. Variants were proposed for the technological schemes of the butanol–toluene mixture separation via combining simple and azeotropic distillation techniques.
