Method for producing overbased calcium sulfonate |
| abstract |
(57) [Summary] [Structure] In a reaction vessel, a reaction product comprising a solvent, a lower alkyl alcohol, a highly reactive lime, water, a hard base, and an alkylbenzenesulfonic acid is formed; The reaction mass is about 2 m as measured by the method described herein. Carbonate at a temperature sufficient to produce an overbased calcium sulfonate having a filtration rate of 1 / min or higher; and from the reaction mixture a titratable basic number (TBN) of greater than about 300. Separating the overbased calcium sulfonate product having an improved filterability of the overbased calcium sulfonate having a titratable basic number (TBN) of greater than about 300. Manufacturing method. [Objective] To provide an improved method for producing overbased calcium sulfonate useful as a lubricating oil additive. |
