In accordance with the present invention, it has been found that the color and stability of basic alkali and alkaline earth metal salts prepared from mixtures containing a phenol can be improved by conducting the reaction in the absence of free oxygen and thereafter post-treating the reaction product with at least one compound capable of displacing the hydrogen of the phenolic hydroxyl groups present in the mixture while maintaining oxygen free atmosphere. Generally, the metal salts will be alkaline earth metal salts of phenols such as calcium and barium salts. A preferred example of the compound capable of displacing the hydrogen of the phenolic hydroxyl group is an epoxide such as ethylene oxide and propylene oxide.
