    Abstract: An alkaline earth metal sulfonate of high alkalinity is prepared by reacting an alkaline earth metal base, e.g. calcium hydroxide, with carbon dioxide in the presence of the metal sulfonate and an alkaline earth metal phenate, there also being present a polar solvent such as benzyl alcohol or tetrahydrofurfuryl alcohol, as well as free phenol in an amount over and above the stoichiometric quantity necessary to form metal phenate by reaction with the metal base. At the end of the reaction the solvent and free phenol are removed from the product by distillation. Preformed metal phenate can be used at the beginning of the reaction or the metal phenate can be formed in situ, starting with free phenol. Also, in place of metal sulfonate, free sulfonic acid can be used initially, with sufficient metal base to convert it to metal sulfonate. The attainment of total base numbers of 400 or more is possible by use of a second dispersant along with the metal sulfonate. This second dispersant, which is used with the sulfonate in the proportion of 0.1 to 1 part per part of sulfonate, can be a thioacid of phosphorus, or metal salt thereof, obtained by reaction of a sulfide of phosphorus on a hydrocarbon; an alkyl phenol or alkyl phenol sulfide, or metal salt thereof; or a monocarboxylic or polycarboxylic acid or anhydride, or metal salt thereof, characterized by a long chain hydrocarbon group of from about 20 to 200 carbon atoms, as for example, a polyisobutenyl succinic acid.
