実験手順

3-(Ethoxymethyl)phthalic acid disodium salt (3.7 mmol) from Example 2 was dissolved in water (40 ml). Potassium permanganate (7.5 mmol) was added and the resulting solution was stirred for 18 h at room temperature. The precipitate formed was filtered off and washed three times with hot water. The combined aqueous phase was evaporated under reduced pressure to approximately one third of the initial volume and cooled in an ice-bath. Concentrated HCl was added carefully for neutralization. The precipitated hemimellitic acid was collected on a glass filter, washed with water and dried (yield: 42%).
