| titleOfInvention | Cleaning agent for lubricating oil and production process thereof |
| abstract | A lubricant oil detergent and a producing process thereof are disclosed. A process for producing a lubricant oil additive having a TBN from about 100 to about 400 includes reacting, at an elevated temperature, of composition (A) an alkyl salicylic acid or an alkyl salicylate ester, composition (B) an alkaline earth metal hydroxide added by one time or plural times during the reaction; composition (C) which contains at least one compound which is (i) an alcohol, or (ii) an carboxylic acid or an carboxylic anhydride; composition (D) base oil; and composition (E) carbon dioxide introduced after the composition (B) by one time, or introduced each time when the composition (B) is added if the composition (B) is added by plural times; solvent having a low boiling point is removed from the reacted mixture after the overbasing under vacuum, and the reacted mixture is filtered to obtain a clear liquid product. |
