Synthesis of triethanolamine-based esteramine surfactants, investigation of structure–property relationships, and application prospects
Abstract
This research is devoted to the synthesis and comprehensive characterization of triethanolamine-based esteramine surfactants obtained through the interaction of triethanolamine with higher aliphatic carboxylic acids (C₁₂–C₁₈). The chemical structure of the synthesized compounds is confirmed using FTIR and NMR spectroscopy, while their physicochemical and surface-active properties are evaluated by surface tension measurements, determination of critical micelle concentration, foaming ability, and emulsification efficiency. Particular attention is given to identifying correlations between molecular structure and functional performance. The results demonstrate that controlled modification of esteramine structure enables purposeful regulation of surfactant properties, which is essential for targeted practical applications.
