Reaction Steps
A mixture of maleic anhydride (88.25 g), oleyl alcohol (483.28 g), p-toluenesulfonic acid monohydrate (8.56 g), and toluene (650 mL) was refluxed under nitrogen. Water was separated from the distillate in a Barrett distilling receiver. When the theoretical amount of water (17 g) was collected, the heating was stopped and the toluene removed in vacuo on a rotary evaporator. The product was a brown oil (532 g) and was used in Example 4 without further purification.
