Reaktionsschritte

One equivalent each of maleic anhydride and n-nonylamine are charged into a 1 liter 3-neck round bottom glass flask containing 300 ml xylene, a reflux condenser with a Dean-Stark attachment, Teflon-coated magnetic stirring bar, and a thermometer. The contents are heated to 120° C. for about 15 hours, the reaction extent being monitored by the amount of water collected. After 1 equivalent of water is collected, the reaction solvent is flash distilled off. The absence of an infrared absorbance at 1830 cm-1 and 1791 cm-1 is evidence of anhydride consumption; the presence of an infrared absorbance at 1772 cm-1 is evidence of imide formation.
