    摘要: An overbased sulfurized alkaline earth metal alkylphenate is prepared by reacting an alkylphenol with an alkaline earth metal hydroxide or an alkaline earth metal oxide and sulfur in the presence of an alkylene glycol or dialkylene glycol, or ether thereof and in the presence of an oil of lubricating viscosity, and optionally further reacting the product thereof with carbon dioxide; thereby forming a sulfurized alkaline earth metal alkylphenate composition in oil. The composition is heated and subjected to steam stripping followed by filtration. The resulting product exhibits an improved rate and efficiency of filtration.
