Abstract
Nitro phenols of the general formula ##STR1## wherein R is an aliphatic substituent of at least about 40 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 and intermediates to such additives. These nitro phenols can be conveniently prepared by nitrating appropriate phenols. Typically nitro phenols are formed by nitration of alkyl phenols having an alkyl group of at least about 50 carbon atoms.
