Abstract

PURPOSE: The reaction between a phenol selected from catechol, 2-alkoxyphenol, and their alkali metal salts and an alkali metal alkyl carbonate is conducted in an organic solvent to produce title compounds used in medicines, agricultural chemicals and perfumes.
CONSTITUTION: The reaction between a compound of formulaI(R1 is H, alkali metal; R2 is H, alkali metal alkyl) such as 2-methoxyphenol and an alkali metal alkyl carbonate of formula II (R4 is alkyl; M is alkali metal) such as sodium propyl carbonate in an amount of 2-7 moles per mode of the phenolic compound is conducted in an organic solvent preferably a combination of n-propanol and N,N- dimethylformamide at atmospheric pressure and 100W200°C to produce the objective compound of formula III such as 4-hydroxy-3-methoxybenzoic acid.
EFFECT: There is no fear of fusing as the reaction is carried out in suspension system, the reaction proceeds at relarively low temperatures in short times and operations are simple.
