Potassium Carbonate → 3-Hydroxy-2-naphthoic acid

Participants

Reaction Steps

The procedure is according to the procedure described in the above examples under a carbon monoxide pressure of 100 bar and at a temperature of 320° C. over a period of about 5 hours, using 10 parts of potassium β-naphtholate, 7.6 parts of potassium carbonate and 75 parts of potassium formate. After working up the reaction mixture, 2-hydroxy-naphthalene-6-carboxylic acid is obtained in a yield of 37.5% of theory, in addition to 5.7% of 2-naphthol-3-carboxylic acid.
