Al-Mulla, Emad A. Jaffar and Wan Yunus, Wan Md. Zin and Ibrahim, Nor Azowa and Ab. Rahman, Mohamad Zaki (2009) Synthesis and characterization of N,N′-carbonyl difatty amides from palm oil. Journal of Oleo Science, 58 (9). pp. 467-471. ISSN 1345-8957; ESSN: 1347-3352

Abstract / Synopsis

N,N′-Carbonyl difatty amides (CDFAs) have been synthesized from palm oil using sodium ethoxide as catalyst. Ethyl fatty esters (EFEs) were produced as a by-product as well as glycerol. The synthesis was carried out by reflux palm oil and urea in presence of ethanol. In this process, palm oil gave 79% pure CDFAs after 8 hours and molar ratio of urea to palm oil was 6.2: 1 at 78°C. Both CDFAs and EFEs have been characterized using elemental analysis, Fourier transform infrared (FTIR) spectroscopy and 1H nuclear magnetic resonance (NMR) technique.
