ABSTRACT:
Compositions made by reacting (I) a metal phenoxide salt of a bridged phenol of 2 to about 20 phenol groups and (II) a carboxylic acid reagent containing from one to about three carboxyl-based groups and a halogen-substituted hydrocarbon-based aliphatic or alicyclic group containing a halogen atom are useful as additives for lubricants and normally liquid fuels. Analogous thiophenoxide-based compositions are similarly useful. These compositions can also be used as intermediates for the preparation of other useful additive compositions through their reaction with alcohols, amino compounds, and reactive small ring heterocycles.
