    Abstract: A process for producing a mixture of sulfides of alkaline earth metal salts of an alkylhydroxybenzoic acid and an alkylphenol comprising the steps of: reacting a mixture of a phenol, a dihydric alcohol and an alkaline earth metal oxide and/or hydroxide (hereinafter referred to as an alkaline earth metal reagent) in an amount of no more than 0.99 gram equivalents per gram equivalent of said phenol; distilling off water and the dihydric alcohol until the amount of the dihydric alcohol becomes no more than 0.6 moles per mole of the alkaline earth metal reagent; reacting the resulting distillation residue with carbon dioxide; and reacting the resulting product with elemental sulfur in an amount of 0.1 - 4.0 moles per mole of the alkaline earth metal reagent.
