Method for controlling reaction mass parameters during the synthesis of alkyd resins

Abstract

Abstract Synthesis of alkyd resins is one of the most common technological processes for deep processing of vegetable oils. In Russia, about 700 thousand tons of alkyd resins are produced per year; so much attention is paid to improving the production process of alkyd resins. Production of synthesis of alkyd resins can be classified as fire and explosive hazardous. One of the main reasons for the high level of accidents in the synthesis of alkyd lacquers and resins is the lack of digitalization of control and management of synthesis. This paper discusses the possibility of using changes in the electrical properties of the reaction mass to control the flow of a chemical synthesis reaction. The principal difference between the proposed approach is that it is proposed to use measurements of DC values directly in the technological process. Studies have shown that it is more promising to use the analysis of the values of the complex resistance module of the reaction mass for the purposes of synthesis control. The advantage of this solution is that the method is more informative, as observations are made in a two-dimensional space of complex values rather than in a one-dimensional one. When using high-frequency alternating current, the module and phase of the complex resistance of the reaction mass are controlled, as well as a number of other parameters (leakage current, q-factor, etc.)
