Fatty amines are commonly prepared from fatty acids; which are themselves obtained from natural sources, typically seed-oils. The overall reaction is sometimes referred to as the Nitrile Process and begins with a reaction between the fatty acid and ammonia at high temperature (>250 °C) and in the presence of a metal oxide catalyst (e.g., alumina or zinc oxide) to give the fatty nitrile. RCOOH + NH3 → RC≡N + 2 H2O In organic chemistry, a nitrile is any organic compound that has a −C≡N functional group. The prefix cyano- is used interchangeably with the term nitrile in industrial literature. Nitriles are found in many useful compounds, including methyl cyanoacrylate, used in super glue, and nitrile rubber, a nitrile-containing polymer used in latex-free laboratory and medical gloves. Nitrile rubber is also widely us… WebMar 15, 2007 · The fatty nitriles could be a positive factor for fuel production, because the carbon numbers (C11–C16) of the major nitriles are within the diesel range (Fig. 4) and the nitrile group in the nitrogenous compounds is easily removed in the hydrotreating at a petroleum refinery (Ahmad et al., 2011).
