  • Process for producing over-based sulfurized alkaline earth metal phenate type detergent
    Patent number: 5178781
    Abstract: A process for producing an over-based sulfurized alkaline earth metal phenate type detergent, which comprises reacting a phenol and a dihydric alcohol with an alkaline earth metal reagent to carry out a metal addition reaction, and reacting sulfur therewith to carry out a sulfurization reaction, and then reacting carbon dioxide therewith to carry out a carbon dioxide treatment, characterized in that the metal addition reaction and the sulfurization reaction are carried out under pressure and closed conditions. The sulfurization reaction may be carried out simultaneously with the metal addition reaction, or, alternatively, with the carbon dioxide treatment after the metal addition reaction. Furthermore, the sulfurization reaction may be carried out between the metal addition reaction and the carbon dioxide treatment.
