US Patent:

41771923, Dec 4, 1979

Filed:

Apr 22, 1977

Appl. No.:

5/790096

Inventors:

Robert E. Kinney - Lawrenceville NJ
George E. Stead - South Plainfield NJ

Assignee:

Mobil Oil Corporation - New York NY

International Classification:

C07D40312
C07D20740

US Classification:

26032622

Abstract:

Succinimides of aminoaryl sulfonic acid salts provide exceptional detergency, viscosity control and anticorrosion properties to lubricants and greases and to other fluid compositions useful in hydraulic systems. Ammonium, alkylammonium, alkali metal, alkaline earth metal and groups IB, IIB, VIB, VIIB, VIII metal salts of aminoaryl sulfonic acid salts, and the salts of sulfanilic acid in particular, can be reacted with alkenyl or alkylsuccinic anhydride, acid or ester, in which the alkenyl or alkyl group may contain from 8 to about 500 carbon atoms, to yield the products of this invention. These products are understood to be novel. Suitable modifications of the aforementioned are the succinimides of di(aminoaryl sulfonic acid) salts, aniline disulfonic acid salts and corresponding aminonaphthalene sulfonate salts which are also useful in the compositions of this invention.

Filed:

Jan 19, 1973

Appl. No.:

5/324939

Inventors:

Robert Earl Kinney - Lawrenceville NJ
Albert Lloyd Williams - Hopewell Township NJ

Assignee:

Mobil Oil Corporation - New York NY

International Classification:

C07D30728

US Classification:

2603436

Abstract:

Alkyl lactone esters or sulfidic esters are prepared by reacting an alkenylsuccinic anhydride with an alcohol or thiol in the presence of an acid-acting catalyst. The esters are useful as dispersants or detergents in aqueous or hydrocarbon systems or they may be further reacted with amines to produce other useful additives for such systems. Esters of monohydroxy alcohols or monothiols or polyhydroxy alcohols or polythiols may be prepared and used in this invention.
