Neutral and low overbased alkylphenoxy sulfonate additive compositions derived from alkylphenols prepared by reacting an olefin or an alcohol with phenol in the presence of an acidic alkylation catalyst

摘要

This invention is directed to neutral and low overbased alkylphenoxy sulfonates derived from alkylphenols prepared by alkylating phenol with an acidic alkylation catalyst having a Hammett (H.sub.o) acidity function of about -2.3 or less (more negative).
