Abstract

Recycling of the Waste Cooking Oils as Non-Ionic Surfactants

Author(s): Abdel Hameed RS

Efficient green synthesis of non-ionic surfactants from waste cooking oil, the used glyceryl trioleate (triolein) as waste cooking oil was collected, purified, and reacted with hydroxyl amine (ethanol amine) and ethylene glycol in the presence of CH3COONa and (CH3COO)2Mn as a catalyst to give octadec-9-enoic acid (2-hydroxy-ethyl)-amide, (OA) and Octadec-9-enoic acid 2-hydroxy-ethyl ester (OE) respectively as non-ionic surfactant. The produced compounds were separated with high yield, purified, and characterized by FT-IR, 1HNMR. The surface properties were studied at different temperatures. the surface parameters such as surface excess concentration (rmax), area per molecule at interface (Amin) and the effectiveness of surface tension reduction (πCMC) were determined from adsorption isotherm. Thermodynamic parameters for micellization and adsorption were calculated and discussed.
