Abstract

The results of the study of the possibility of maintaining the physicochemical properties of purified halogenated solvents in a stable state are summarized. Particular attention is paid to the possibility of stabilizing solvents during multiple use. The novelty is to justify the choice of the most effective stable azeotrope to remove contamination. A kinetic analysis of the physicochemical cleaning of metal optics from contaminants by azeotropes was carried out. Diagnostics of the optical breakdown threshold made it possible to find more efficient azeotropes. The results of a study of the possibility of maintaining stable properties of purified halogenated solvents are presented. Ways to increase the stability by obtaining azeotropes of high purity with an inhibitor in the distillation purification of contaminated solvents were investigated and proposed. On the example of metal optics, the fundamental idea of the physicochemical process of metal cleaning as an interconnected process of interaction between the energy characteristics of the washing mixture and the energy characteristics of the surface layer is substantiated.
