-115- ADDITIVE COMPOSITIONS CONTAINING AMINOPHENOL COMBINATIONS USEFUL AS LUBRICANT AND FUEL ADDITIVES Abstract of Disclosure Disclosed are nitrogen-containing organic compo- sitions comprising the combination of amino phenols, wherein said phenols contain a substantially saturated hydrocarbon- based substituent of at least 10 carbon atoms with one or more of the following compositions: (I) one or more carboxylic derivative composi- tions or post-treated carboxylic derivative compositions wherein said carboxylic derivative composition is produced by reacting at least one succinic acylating agent with a reactant selected from the group consisting of (a) amines, (b) alcohols, (c) reactive metal or reactive metal compo- unds, and (d) a combination of two or more of (a) through (c), wherein said substituted succinic acylating agents consist of substituent groups and succinic groups wherein the substituent groups are derived from polyalkene, said polyalkene being characterized by a Mn value of 1,200 to about 5,000 and a Mw/Mn value of about 1.5 to about 6, said acylating agents being characterized by the presence of their structure of an average of at least 1.3 succinic groups for each equivalent weight of substituent groups, said post-treated carboxylic derivative compositions being prepared by reacting one or more post-treating reagents with said one or more carboxylic derivative compositions; (II) at least one chlorine-containing compound selected from the group consisting of chloroaliphatic hydrocarbon-based compounds, chloroalicyclic hydrocarbon- based compounds or mixtures thereof; (III) at least one sulfurized olefinically unsaturated compound. Also disclosed are concentrates of these com- positions and lubricants and fuels containing these com- positions.
