Abstract
In the recent years, interest in obtaining and studying surfactants synthesized from natural raw materials, has been increased. Flaxseed oil, rich in polyunsaturated fatty acids, is a significant object of study in this field. The synthesis and analysis of the properties of amides derived from linseed oil are important for understanding their potential applications in industry. Previously published studies claimed that the amidation of linseed oil fatty acids is possible only with the use of diethanolamine. However, new research has shown that in addition to diethanolamine, diethylamine can also be successfully used for this process. This discovery opens new prospects for the synthesis of fatty acid amides of linseed oil and expands the possibilities of research in this area.
