4-Aminophthalic acid Use and Manufacturing
1 g (4.73 mmol) of 4-nitrophthalic acid is dissolved in 10 ml of anhydrous ethanol. The solution is stirred at room temperature and degassed under argon. 50 mg of 5percent palladium/carbon are added all at once and hydrogen is bubbled through the solution. After 3 hours, the solution is filtered on celite and then evaporated. [00347] Orange-coloured oil. m=820 mg. Y=96percent. 1 g (4.73 mmol) of 4-nitrophthalic acid is dissolved in 10 mL of anhydrous ethanol. The solution is stirred at room temperature and degassed under argon. 50 mg of palladium/charcoal (5percent) are added in a single portion and hydrogen is bubbled into the solution. After 3 hours, the solution is filtered through Celite and then evaporated. [00137] Orange-coloured oil. m=820 mg. Y=96percent.
