TECHNOLOGICAL ASPECTS OF OBTAINING AMINOALDEHYDE OLIGOMER MODIFIED WITH CROTONALDEHYDE
Abstract
Today, there is a growing demand for oligomers containing amino groups in the world, including in woodworking, textile, plastics, as well as in many other industries, such as the fur industry.In our republic, the work aimed at the purposeful use of waste from cocoon processing plants is developing rapidly.The resulting oligomers are used as fillers in the leather-fur industry. Because today, obtaining hydrophilic fillers using local raw materials is one of the urgent problems of science. Taking this into account, in this article oligomers based on croton aldehyde and diethanolamine were obtained from cocoon waste and the extraction technology was explained. Mechanisms of synthesis of oligomers are presented.The sequence and schemes of technological processes are presented. KEYWORDS:croton aldehyde, diethanolamine (DEA), sericin, cerine, amino acid, condensation, vacuum chamber, modification, aminoaldehyde
