Abstract

Palm oil acid fraction-based monoethanolamine (MEA) diethanolamine (DEA) triethanolamine (TEA) methylaminoethanol (MAE) piperidine (PP) morpholine (Mr) diethylamine (DEtA) triethylamine (TEtA) ethylenediamine (EDA) diethylenetriamine (DETA) and polyethylenepolyamine (PEPA) salts were synthesised. By stalagmometric method it was established that the synthesised salts are highly surfaceactive. DEA and TEA-based salts reduce the interface tension at the air-water surface from 72.0 mN m-1 down to 25.7 and 24.2 mN m-1 (25C). Using surface tension isotherms of the salts their colloidal-chemical parameters were calculated. An increase in the number of ethylol groups in the surfactant composition decreases critical micelle concentration (CMC) and area per molecule at the interface (Amin) and increases effectiveness of surface tension reduction (pCMC) and surface excess concentration (Gmax). It was revealed that DETA-based salt has a higher petroleum-collecting ability than the other salts.
