ABSTRACT:
A detergent additive for lubricating oils is prepared by reacting an alkyenolsulfide with an oxide or hydroxide of a earth-alkali metal and carbonating the reaction product with carbon dioxide, the reaction being carried out in the presence of a promoter, selected in the class of the organic nitrogen compounds, and possibly of a co-promoter; the temperature and the time of the reaction are depending on whether the co-promoter is present. The resulting product shows improved detergency and flow-ability properties.
