The present invention provides novel polymeric amine compositions employing amine compounds having multiple tertiary amine groups. Methods of making these new compositions are also disclosed. Amine compositions and amine-epoxy compositions employing the polymeric amine compositions of the present invention are also provided.

Amine composition

The present invention relates to processes for the catalytic hydrogenation of aromatic amines to their acyclic counterparts using a ruthenium catalyst on a lithium aluminate support. The hydrogenation process comprises contacting an aromatic amine with hydrogen in the presence of a ruthenium catalyst under temperature and pressure conditions suitable to effect ring hydrogenation. The process is especially useful for hydrogenating aniline to cyclohexylamine.

Hydrogenation of aromatic amines to alicyclic amines using a lithium aluminate-based catalyst

This invention relates to an improved hydrogenation process for the preparation of etheramines. In the process, cyanoethylated alcohols, i.e., the reaction product of an alcohol with (meth)acrylonitrile, are contacted with hydrogen in the presence of a sponge cobalt catalyst. The improvement in the process resides in effecting the hydrogenation process utilizing a cyanoethylated alcohol feedstock contaminated with byproduct acrylonitrile and utilizing a solvent that solubilizes byproduct (meth)acrylonitrile present in the feedstock. Specific classes of solvents employed are ethers and amides.

Aminopropylation of alcohols in the presence of amide or ether solvents

A method for racemizing an enantiomer of an alkoxyamine represented by formula I ##STR1## in which R.sub.1 and R.sub.2 are the same or different C.sub.1 to C.sub.20 alkyl group. A feed containing an enantiomer of the alkoxyamine is passed over a nickel or cobalt catalyst in the presence of hydrogen and ammonia. The racemic mixture formed by this method contains substantially no by-products.

Racemization of optically active alkoxyamines

A novel composition of the formula: ##STR1## wherein the carbon rings are fully fluorinated.

Perfluorinated 2-ISO propyl derivative compounds

A method of vapor bath soldering wherein vapor bath compositions include compounds of the formula: ##STR1## wherein the carbon rings are fully fluorinated and R is selected from the group consisting of fluorine, --CF.sub.3 or --CF(CF.sub.3).sub.2.

Perfluorinated propyl derivative compounds for vapor bath soldering

Novel compositions include compounds of the formula: ##STR1## wherein the carbon rings are fully fluorinated.
