ABSTRACT:
Amino phenols of the general formula ##STR1## wherein R is a substantially saturated, hydrocarbon-based group of at least about 30 aliphatic carbon atoms, a, b and c are, for example, each 1, 2 or 3, and Ar is an aromatic moiety such as a benzene nucleus, naphthalene nucleus or linked benzene nuclei, are useful additives for fuels and lubricants. These amino phenols can be conveniently prepared by nitrating an appropriate hydroxy aromatic compound and reducing the nitro groups to amino groups. Typically such amino phenols are formed by nitration and reduction of alkyl phenols having an alkyl or alkenyl group of at least about 50 carbon atoms.
