Development of Resource-Saving Technologies in the Production of Organosilicon Enamels Basing on Rectification

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.
