Patent number: 5783735Abstract: A process for preparing polymeric amides is disclosed. The process comprises sequentially reacting a hydrocarbon polymer functionalized (e.g., via the Koch reaction) to contain acid, ester, thioacid and/or thioester groups with a heavy polyamine to form a partially derivatized product in which at least about 85% of the functional groups are converted to heavy (thio)amide groups, and then reacting the partially derivatized product with an excess of light amine to complete the derivatization by converting substantially all of the remaining functional groups to light (thio)amide groups. Products of the foregoing process are also disclosed, which products are useful as additives in fuels and in lubricants.Type: GrantFiled: May 25, 1995Date of Patent: July 21, 1998Assignee: Exxon Chemical Patents Inc.Inventors: Jacob I. Emert, Joseph V. Cusumano, David C. Dankworth, William D. Diana, William B. Eckstrom, Keith R. Gorda, Antonio Gutierrez, Jon E. Stanat, Warren A. Thaler, Stephen Zushma

Patent number: 5773567Abstract: Processes for producing saturated polymers monosubstituted with carboxylic amides are disclosed. One process comprises reacting a monounsaturated hydrocarbon polymer with carbon monoxide and a polyamine containing at least two amino groups at least one of which is a reactive amino group, in the presence of a catalyst comprising at least one member selected from the group consisting of the transition metals of Group 8 to 10 and the metal compounds thereof. Another process comprises reacting a polyamine containing a reactive amino group with a monofunctionalized, saturated hydrocarbon polymer containing a carboxylic acid or carboxylic ester functional group, the monofunctionalized hydrocarbon polymer obtained by reacting a starting mono-unsaturated hydrocarbon polymer with carbon monoxide and water or alcohol in the presence of a Group 8-10 transition metal catalyst. The products of the processes are useful as additives in lubricating oils and in fuels, for example, as dispersants and/or detergents.Type: GrantFiled: June 17, 1996Date of Patent: June 30, 1998Assignee: Exxon Chemical Patents IncInventors: Jacob Emert, Richard H. Schlosberg, David E. Gindelberger, Roy L. Pruett

Patent number: 5773393Abstract: The present invention includes a composition which comprises a major amount of an oil of lubricating viscosity and a minor amount effective to inhibit metal corrosion of a soluble additive mixture comprising(A) at least one amide compound of a mono- or polycarboxylic acid or reactive derivative thereof; and(B) at least about 0.1 mole of at least one amine per mole of amide, provided that when (A) is an amide of a dicarboxylic acid and the amine is an alkanol amine, the mixture contains more than 0.5 equivalent of the amine (B) per equivalent of amide (A).The compositions of the invention exhibit improved corrosion-inhibiting properties and the compositions are useful in a variety of lubrication applications. In particular the compositions are useful as hydraulic fluids.Type: GrantFiled: June 17, 1997Date of Patent: June 30, 1998Assignee: The Lubrizol CorporationInventor: Paul Ernest Adams
