The object of the research is a butanol-toluene mixture (BLS), which is a waste product of organosilicon enamels and consists of organic substances. In order to create a basic technological scheme of separation, thermodynamic-topological analysis was applied that takes into account the peculiarities of the rectification process in the poly-azeotrope mixture. The presence of 7 binary and 5 ternary azeotropes in the system was found. Singular points of the pentatope are considered. The distillation and rectification zones are determined. Flow graphs options separation were drawn, which can be the basis for the development of a technological scheme for the separation of the studied mixtures.
