ABSTRACT OF THE DISCLOSURE A process for carbonating a solid, dry alkali metal phenate with carbon dioxide under pressure to form the corresponding alkali metal carboxylate, where the temperature during the first step is maintained at below 135°C until at least 25 mole percent of the theoretical amount of C02 required for complete carbonation is absorbed by the phenate, the temperature is then raised to above 135°C and carbonation resumed. 26,299-F 26,299-F
