SYNTHESIS, AND SURFACE-ACTIVE PROPERTIES OF PALM FATTY ACID AND 1(2-HYDROXYETHYL PIPERAZINE)-BASED ESTERAMIDE QUAT
V. K. TYAGI
In this study, an attempt has been made to synthesize esteramide quat by esterification of palm fatty acids with 1(2-hydroxyethyl piperazine) followed by quaternization with dimethyl sulphate (DMS). The optimum reaction conditions for esterification of palm fatty acids and 1(2-hydroxyethyl piperazine) were found to be 170Â°C reaction temperature and 150 mmHg pressure. The obtained esteramide was subjected to quaternization with different molar ratios of DMS. The consequences revealed that esteramide to DMS ratio of 1 : 0.95 and duration of quaternization for 2 h yielded esteramide quat of maximum cationic content, i.e., 64.9%. The instrumental analysis, viz. FT-IR, 1H NMR, 13C NMR verified the esterification and subsequent quaternization of the obtained esteramide quat. Furthermore, the surface-active and performance properties of synthesized esteramide quat were also evaluated.
