Distillation process for producing a low tpp phenate |
abstract |
Disclosed herein is a process for preparing a sulfurized non-overbased calcium phenate detergent having a reduced content of un-sulfurized alkyl-substituted phenol and its salt. The process steps involve adding an organic solvent to the detergent, wherein the organic solvent has a boiling point of equal or above the boiling point of the un-sulfurized alkyl-substituted phenol. Distilling the organic solvent from the detergent to reduce the content of the un-sulfurized alkyl-substituted phenol. |
