ABSTRACT:
Novel compounds of the general formula ##STR1## wherein each R.sub.1 is independently a tertiary alkyl group containing from 4 to about 8 carbon atoms and each of X, Y and Z is independently hydrogen or a hydrocarbon-based group, provided at least one of X, Y and Z is an aliphatic hydrocarbon group containing at least 7 carbon atoms, and wherein R.sub.1 is different from the at least one of X, Y and Z that is an aliphatic hydrocarbon group containing at least 7 carbon atoms, R.sub.2 is an alkylene or alkylidene group, and n is a number ranging from zero to about 4. Also disclosed are methods for preparing novel phenolic compounds, organic compositions, including lubricants based on oils of lubricating viscosity and fuels based on normally liquid fuels and additive concentrates containing the novel phenolic compounds of this invention.
