Technology for Treatment of Solvents’ Liquid Waste from Silicone Enamels Production

Abstract

There was presented thermodynamic and topological analysis of butanol and toluene mixture that formed as waste in paint-and-varnish industry. There was carrying out experimental investigation of liquid – liquid equilibrium state in system of ethanol – toluene – benzene chloride. There was developed method of chromatographic procedure of investigated mixture. There were synthesized the main routs of butanol and toluene mixture’s separation as flow graphs. There was offered options of process flow scheme for butanol and toluene mixture’s separation by means of combination of simple and azeotropic rectification. Benzene was offered as azeotropic agent.
