Abstract
- The synthesis of diethanolamide surfactant from used cooking oil was systematically studied using modified zeolite as catalyst. The activated zeolite was obtained by dispersing natural zeolite in sulfuric acid (H 2 SO 4 ) solution. Potassium carbonate (K 2 CO 3 ) was loaded into activated zeolite by wet impregnation method. The methyl ester obtained from transesterification reaction of used cooking oil was refluxed with diethanolamine (C 4 H 11 NO) solution over K 2 CO 3 /zeolite catalyst in the production of diethanolamide surfactant. The amidiation reaction over K 2 CO 3 /zeolite effectively produced 92% of diethanolamide surfactant with the highest selectivity of methyl oleate. Diethanolamide surfactant showed stable foam and emulsion with the reduction of surface tension as much as 3.3 dyne/cm.
