Preparation of highly basic salts of metals alkaline-earth - metal organic acids and oil compositions containing them,

摘要

The invention relates to the preparation of highly basic salts of metals alkaline-earth - metal organic acids and of the oil compositions containing them. / p & & p & is react a hydroxide of alkaline - earth metal hydroxide, with the carbon in the presence of methanol and optionally of a volatile thinner, has a lower temperature at 50c; the mixture, the product of reaction with one or more organic acids or salts of organic acids; it is react the mixture obtained with the carbonic anhydride microsecond, separate the water and methanol, the mixture of reaction eliminated the materials and inorganic solid crystalline if there are to be presented. / p & & p & use of the products such as detergents and dispersants in lubricating oils.
