EXAMPLE 2; Synthesis of perfluoro-N¹ , N⁷ -dioctanimidoylheptanediimidamide (DPIA-56); (i) Methyl perfluorooctanoate; A 2-1, four-necked, round-bottomed flask equipped with stirrer, addition funnel, thermometer and reflux condenser, is charged with 828 g (2 mol) of dried perfluorooctanoic acid, 16O g (5 mol) of methanol. The mixture is stirred and 50 ml concentrated sulfuric acid is added dropwise. Then the mixture is heated to reflux for 4 hr. At the end of the reflux period the mixture is cooled to room temperature and poured into 2 1 cold water. After separation of the phases, the lower organic phase is washed with water till pH neutral and dried over CaCl₂. Distillation of the crude gives 762 g (89%) of methyl perfluorooctanoate, bp 160⁰C.
