ABSTRACT:
An alkyl phenol having from about 20 to about 300 carbon atoms, formaldehyde and trishydroxymethylaminomethane are reacted and the resulting product is then reacted with boric acid, dialkyl phosphonate or a diaryl phosphonate to produce the corresponding borate or phosphonate derivatives. These derivatives are particularly useful as detergents in organic media such as lubricating oils, greases, fuels, heat-exchange fluids and transmission fluids.
