ABSTRACT:
Processes for preparing normal and overbased metal sulfurized alkylphenates. The processes am characterized by a sulfurization reaction using a lower carboxylic acid catalyst which does not use a polyol promoter, e.g., ethylene glycol. The process affords a metal sulfurized phenate product which is essentially free of polyol oxidation products. The products are useful as additives for lubricating oils.
