The goals of the dissertation: Synthesizing deep eutectic solvents based on choline chloride with the compounds of 2-alkylbenzimidazole/ethylene glycol and determining their structures; using synthetic deep eutectic solvents to enrich and separate Omega-3,6,9 from waste fat in accordance with the facrories’ procedure of processing Vietnamese basa fish for export. | MISNISTRY OF VIETNAM ACADEMIY OF EDUCATION AND TRAINING SCIENCE AND TECHNOLOGY GRADUATE UNIVERSITY OF SCIENCE AND TECHNOLOGY LE THI THANH XUAN SYNTHESIS OF SOME DEEP EUTECTIC SOLVENTS FROM 2-ALKYLBENZIMIDAZOLE CHOLINE CHLORIDE AND THEIR APPLICATION FOR EXTRACTION OF OMEGA-3 6 9 FROM THE FAT OF VIETNAMESE BASA FISH IN MEKONG DELTA Major Organic chemistry Code 9 44 01 14 A SUMMARY OF THE DISSERTATION ON ORGANIC CHEMISTRY HO CHI MINH CITY 2021 This dissertation is completed in Graduate University of Science and Technology Vietnam Academy of Science and Technology Supervisor 1 Ho Son Lam Asso Prof. Dr Supervisor 2 Cu Thanh Son Dr This dissertation will be defended by the Committee of Dissertation Evaluation at institutional level at Graduate University of Science and Technology Vietnam Academy of Science and Technology at . 2021 This dissertation could be accessed at - The library of Graduate University of Science and Technology - National Library of Vietnam 1 INTRODUCTION Fish raising industry especially that of Vietnamese basa fish is under strong development in the Mekong Delta meeting domestic consumption demand and serving as raw processing materials for export promoting the development of Vietnam s seafood industry. However we have used Vietnamese basa fish mainly their meat fillet for export and primary fats for the domestic market. By- products of the processing process such as head bones fat skin. have not been utilized effectively but used as a fertilizer or animal feed instead. If there is no appropriate treatment we will not only waste the nutrients contained in it but also leave them as sources of pollution to the environment. In recent years in Vietnam there have been a large number of studies on the separation of omega compounds by such methods as Hydrolysis of lipids in alkaline environment and urea precipitation or using the thermal fractionation method at high level to improve the economic efficiency of the catfish processing. However the projects .
