Abstract
A process is disclosed for preparing overbased carbonated sulfurized magnesium alkylphenates. In the process, magnesium methoxide is carbonated and then contacted with an alkylphenol to form a normal magnesium phenate. The normal magnesium phenate is sulfurized and then contacted with an additional amount of carbonated magnesium methoxide to form the overbased sulfurized magnesium phenate.
