실험 절차

2-Hexadecylsuccinic anhydride (10.5 g, 31.3 mmol), 3-(3,5-di-t-butyl-4-hydroxyphenyl)propanoic acid hydrazide (9.2 g, 31.3 mmol) and 10 ml of toluene were combined and refluxed for one hour under a nitrogen atmosphere with the azeotropic removal of water. Solvent was then removed under vacuum as the mixture was warmed to about 130° C. After 20 minutes, the reaction mixture was cooled and the vacuum was removed. The resulting viscous yellow mass was further chilled in an acetone/dry ice bath causing the mass to harden for facile removal from the reaction vessel. About 19 g of a viscous yellow gum was obtained that solidified to a translucent white solid upon standing for several days at room temperature.
