Abstract: This article presents the results of obtaining an alkene derivative of chitin from a chitin biopolymer.Chitin from a crab shell was used for the reaction in the work.The reaction was carried out in the presence of EDC, NHS, and DMAP.Acrylic acid was first used to introduce a double bond into the chitin molecule.It was found that at 20-40°C the reaction does not occur, and at 50°C the reaction follows the Michael reaction path.Then, using the same method, a reaction was carried out with but-3-enoic acid.Using a less electrophilic acid, the expected compound was obtainedThe article concludes that to obtain an alkene derivative of chitin, it is necessary to use a less electrophilically activated acid to ensure the reaction proceeds in the desired direction.The structure of the compound was identified using nuclear magnetic resonance.
