Reaction Steps

Dipotassium 2,5-dihydroxyterephthalate was prepared in the known “Kolbe-Schmidt” type reaction from hydroquinone. Hydroquinone was mixed with potassium carbonate and potassium formate, the latter which acted as a solvent when molten. The mixture was heated to 200° C. with stirring to provide a homogeneous solution. Excess carbon dioxide was bubbled through the stirred solution for about 8 h. Excess carbon dioxide optionally may be recycled. The reaction mass was drowned in water, and filtered. When the drowned and stirred reaction mass was filtered, the sparingly soluble dipotassium 2,5-dihydroxyterephthalate was separated from water-soluble potassium formate and potassium carbonate.
