Reaction Steps
To a solution of 28.2 gm (0.101 mole) oleic acid in toluene, was added 12 gm hydroquinone (0.11 mole) and 1.7 gm p-toluenesulfonic acid (0.01 mole). Water was withdrawn into a Dean-Stark trap as the solvent was refluxed for two days. The solution was cooled and washed with 100 ml water four times, and the solvent was evaporated in vacuo. The crystalline residue was recrystallized from methanol to give 15 gm hydroquinone oleate (40% theoretical) colorless compound, single spot (TLC). The melting point was 85° C. and the NMR was consistent with the structure of hydroquinone oleate.
