Abstract
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.
