Provided are polyurea and lithium complex grease compositions whose anti-fretting properties are improved by the addition of an anti-fretting additive which comprises the reaction product of an alkenyl succinic acid or anhydride having the structural unit represented by the following formula: ##STR1## in which R is an alkenyl of 10 to 35 carbon atoms, and an alkanolamine which is represented by the following formula:

Anti-fretting additive for grease comprising the reaction product of an

A catalytic process for preparing novel hydrocarbonaceous polymeric compounds by contacting a first hydrocarbonaceous compound with a second hydrocarbonaceous compound in the presence of a basic nitrogen catalyst in the substantial absence of water. The novel polymeric type materials provided by the process are useful as nonionic surfactants, as biodegradable detergents, as chemical intermediates in the production of anionic detergents, as lubricating oil additives, and as anti-rust and anti-icing additives in fuels.

Catalytic process

A process for producing secondary alkyl primary amines having from 10 to 50 or, from about 10 to about 13, or from about 14 to 50 carbon atoms from crude n-paraffin oximes derived by the photonitrosation of C.sub.10 to C.sub.50 or C.sub.10 to C.sub.13 or C.sub.14 to C.sub.50 n-paraffins, said process comprising hydrogenation in a polar solvent in the presence of ammonia and a metal catalyst. The crude n-paraffin oximes are contaminated with ketones and nitroso halides. By the process of this invention, these impurities are likewise converted into the corresponding secondary alkyl primary amines.
