| titleOfInvention | Manufacturing method for high-alkali type lubricating oil composition |
| abstract | PURPOSE: To obtain a lubricating oil composition having good clean dispersiveness, high heat resistance, and high total basicity by making higher the basicity of acid anhydride calcium salt and calcium naphthenate with calcium carbonate. n CONSTITUTION: Calcium hydroxide and calcium oxide are suspended in an alcohol, and alcohol-inorganic compound complex obtained by the action of carbon dioxide on the suspension is then reacted with an acid anhydride. The mixture is then heated at 200W300°C in an organic solvent containing a mineral oil and naphthenic acid or calcium naphthenate, or the mixture containing acid anhydride, calcium hydroxide, calcium oxide, organic solvent, alcohol, mineral oil, and naphthenic acid or calcium naphthenate is heated at 200W300°C while being treated under the action of carbon dioxide. Thus, the basicity of acid anhydride calcium salt and calcium naphthenate can be made higher by calcium carbonate. n COPYRIGHT: (C)1980,JPO&Japio |
