Abstract
Metal phenates especially overbased phenates are prepared by reacting a basic metallic compound with a mixture of an alkyl phenol and an alkyldihydroxybenzene. The products are useful as lubricant additives with improved antirust properties, and when overbased, with higher basicity and lower viscosity.
