Feb 13, 1978

Appl. No.:

5/877354

Inventors:

Arthur W. Langer - Watchung NJ

Assignee:

Exxon Research & Engineering Co. - Florham Park NJ

International Classification:

C01B 613

US Classification:

423286

Abstract:

Chelated lithium aluminum compounds are prepared by mixing a lithium aluminum compound such as a lithium aluminum hydride with a chelating agent wherein the agent contains at least one nitrogen atom. The chelating agent is a tertiary polyamine or aminoether. The resultant chelate is used for a variety of processes such as separations, catalytic reactions, substitution reactions, reductions, electrochemical reactions, and also as an oil and fuel additive.

Appl. No.:

5/711138

Inventors:

Thomas A. Whitney - Roselle NJ

Assignee:

Exxon Research & Engineering Co. - Linden NJ

International Classification:

C07C 8738
C07C 8740

US Classification:

260563R

Abstract:

Crude trans-1,2-cyclohexanediamine (DACH) contained in a mixture of amines derived as a by-product from the manufacture of 1,6-hexanediamine (HDA) or any other synthesis process crude by-product stream may be directly resolved into its optical isomers by using a mixture of tartaric acid and a second acid selected from the group consisting of C. sub. 1 to C. sub. 8 carboxylic acids and HCl, without first separating the DACH in high purity from the mixed amine component by-product stream. Alternatively, racemic DACH may be separated from a crude mixed amine component by-product stream by use of oxalic, sulfuric and/or nitric acids. This racemic product may then be optically resolved by techniques known in the art.
