ABSTRACT:
An overbased material is prepared in a liquid ester medium which is subject to saponification upon exposure to strong base, by preparing a mixture of an acidic material having at least about 8 carbon atoms in a volatile oleophilic medium which is substantially inert to base; adding to the mixture a stoichiometric excess of a metal base; adding to the mixture a gaseous acidic material under conditions to react with substantially all of the stoichiometric excess of the metal base; and adding the liquid ester medium to the resulting material.
