Diethanolamine stearic acid amide
WebThermal and catalytic amidation of stearic acid with ethanolamine in hexane was investigated using both microporous H-Beta and ZSM-5 zeolites, and mesoporous … WebThe amidation is a formation reaction of an amide compound (Clason, 1986). According to Kirk and Othmer (1986), when the long chain fatty acids such as lauric acid and stearic acid combined with alkanolamine and heated at 140-160 0C, with or without a catalyst will result an amidation reaction.
