OBTAINING, RESEARCH AND APPLICATION OF ION EXCHANGER RESINS BASED ON COOLIGOMERS

Abstract At present, the chemistry of high-molecular compounds is one of the fastest growing areas of independent science. In modern times, there is not a single area of human activity in which high-molecular compounds are not used. High-molecular compounds have existed since very ancient times. However, many believe that these compounds became known by chemists after obtaining them artificially or synthetically. This is not the right idea. Thus, while the synthetic production of member substances began at the beginning of the ⅪX century, high-molecular compounds were known even before 100 thousand years. Since its inception, humans have always been in contact with high-molecular compounds in their daily lives. So, cellulose wool fibers, which are the basis of wood, skin wheat starch, which is the basis of potatoes, etc. it is included in the order of highmolecular compounds. They feed people, dress them, provide them with medicines, etc. it is necessary. For this, the science of chemistry, including the preparation of compositional materials on the basis of chemical compounds, new and used for various purposes, is one of the pressing problems of the day. All this has always been the most important funds for life. One of the important directions of modern chemistry is the obtaining of materials with new composition and necessary properties that can replace natural existing materials and their application in various fields of Industry [1]. The application of high-molecular ion-exchange compounds in various fields of Science and technology is one such direction. The research work carried out also relates to this topic. Ion-exchange resin high-molecular compounds are produced in various types in the UK, France, the Netherlands, Italy, Japan and other countries. Currently, the industry produces ionites (ion exchanger resins) of the following general grouping: KY ─ cationite "универсальный", strong acid cationite; KБ ─ cationite "буферный", weak acid cationite; AB ─ anionite “высокоосновный”, strong essential anionite; AH ─ anionitis” низкоосновный", weak essential anionitis. Most ion exchanger resins made on the basis of high-molecular compounds are solid, insoluble, compounds with limited swelling capacity [2-3]. Ion-modifiers based on cooligomers modified with nitrogen-containing compounds were used for various purposes and positive results were obtained [4-5]. Ion exchanger resins are those that contain many functional groups in their composition, including -OH, >NH, -NH2, -COOH, etc. as they belong to polyfunctional compounds, their application areas are different. Sulfocationite prepared on the basis of modified cooligomer was used in softening of technical water and positive results were obtained. In laboratory conditions, tests were carried out to reduce the water hardness by trilometric method and positive results were obtained. Sulfocationites based on functionalized cooligomers are recommended to be used in softening of technical water in thermal power plants. The innovation in the research work is to synthesize an environmentally friendly and economically viable ion exchanger resin with a new composition and explore its application areas.References: 1.
