SOLUBILITY IN AQUEOUS SYSTEMS BASED ON SODIUM DICARBAMIDOCHLORATE, MONOETHANOLAMMONIUM ACETATE, ETHANOL AND ACETAMIPRID

Background: When producing high-quality raw cotton, a major role is played by a modern lossless cotton harvest. This is due to the use of effective defoliants to remove cotton leaves. In order to obtain a high cotton crop, along with carrying out agrotechnical measures, it is necessary to protect plants from all kinds of pests and diseases, as well as to conduct high-quality defoliation. Defoliation - this artificial pre-harvest removal of plant leaves. After it is carried out by chemical substances - defoliants, nutrients are mixed from the vegetative organs into generative ones - fruits and seeds. Purpose. The physical chemical substantiation of the process of obtaining a new defoliant, which has both physiological and insecticidal activity based on sodium dicarbamidochlorate, monoethanolammonium acetate, ethanol and acetamipride. Methodology. The determination of chlorate - ion was carried out by volumetric permanganometric, sodium - by flame photometric methods. The viscosity of the solutions was measured using a HPV viscometer, and the pH of the solutions was determined using a pH meterFE20 METTLERTOLEDO.Originality. Polythermal and “composition-properties” diagrams have been created based on the study of solubility in a system involving water, sodium dicarbamidochlorate, monoethanolammonium acetate, ethanol and acetamipride. Findings. Justification of technological processes for the production of a defoliant with defoliation, physiological and insecticidal activity based on sodium dicarbamidochlorate, monoethanolammonium acetate, ethanol and acetamipride. We studied the physicochemical properties of solutions of systems [70 % (99.65 % NaClO3∙2CO(NH2)2 + 0.35 % NH2C2H4OH·CH3COOH) + 30 % H2O] - [90 % C2H5OH + 10 % C10H11ClN4] depending on the ratio of the components. Highlights: - fields of crystallization of components are delimited into systems; - the optimal technological parameters for obtaining a liquid defoliant were established.
