Yield:89-86-1 96.7%
Reaction Conditions:
with hydrogenchloride;CO2;potassium carbonate in water
Steps:
3 Example 3
Example 3 92.5g (0.84 mole) of resorcinol and 200.2 g (1.45 mole) of potassium carbonate are added to the filtrate obtained in Example 2 and reacted together at 95-105°C, for 2 hours maintaining 5 atm of CO2. The reaction mixtures are filtered at this temperatures, the filtered precipitates are dissolved in 380 g of water, and neutralized by 180 g of concentrated HCl. The white solid thus obtained is 125.2 g (0.81 mole, yield 96.7%) of 2,4-dihydroxybenzoic acid, having a melting point of from 224 to 226°c.
