ABSTRACT:
Hydroxy aromatic compositions containing (a) a hydroxyl group bonded directly to a carbon of an aromatic nucleus, (b) a hydrocarbon-based substituent of at least about 50 aliphatic carbon atoms bonded directly to a carbon atom of an aromatic nucleus, (c) at least one methylol or lower hydrocarbyl substituted methylol substituent bonded directly to a carbon atom of an aromatic nucleus, and not having any alkylene linkages between carbon atoms of two aromatic nuclei are useful as additives for normally liquid fuels and lubricating oils. These hydroxy aromatic compositions are also useful as intermediates for preparing other additives for fuels and lubricants. Typical hydroxy aromatic compositions of the present invention are formed by reaction of formaldehyde with an alkenyl- or alkyl-substituted phenol wherein the alkyl or alkenyl substituent contains an average of about 50 carbon atoms.
