Research demonstrates the synthesis of novel biazocyclic derivatives from a three-acid fraction, indicating new chemical pathways.
During the research, the optimal conditions for the synthesis of 2-hexadecyl-2-imidozoline C20H40N2, 2-octadecyl-2-imidozoline C21H40N2, and 2-octadecyl-2-imidozoline C21H38N2 from the three-acid fraction (TAF) obtained by adsorption of wood chips and extraction in isopropyl alcohol were determined. 98% ethylenediamine was used for the synthesis. TAF is a mixture of palmitic, oleic, and linoleic acids, present in a ratio of 30.3+22.7+42.3% by mass, respectively.
