Ethylene amines are manufactured by a process wherein ethylene dichloride is reacted with ammonia and the mixture is stripped of unreacted ammonia. Sodium hydroxide equivalent to the chloride present is added and large quantities of sodium chloride result. Part of the ethylene amines product is lost when this salt is separated from the product amines. Recovery of the ethylene amines from the salt and production of a substantially amine-free salt is accomplished by the disclosed process involving...

Process for preparing an amine by reacting a primary or secondary alcohol, aldehyde or ketone with hydrogen and a nitrogen compound selected from the group consisting of ammonia and primary and secondary amines in the presence of a catalyst whose preparation has involved precipitation of catalytically active components onto monoclinic, tetragonal or cubic zirconium dioxide.

The invention relates to (1S)-1-isobutoxymethyl-3-methylbutylamine useful as an intermediate in the synthesis of sodium (2S,3S)-3-[[(1S)-1-isobutoxymethyl-3-methylbutyl]carbamoyl]oxirane-2-carb- oxylate and a process for production thereof. The process comprises reacting L-leucinol with a compound represented by the following formula in the presence of a base and reducing the obtained (1S)-1-(2-methyl-2-propenoxymethyl)-3-methylbutyl-amine: ##STR00001## [in which X is a leaving group].

The present invention relates to amine derivatives represented by formula (1) or salts thereof. ##STR1## R.sup.3 represents C1-C3 alkyl, hydroxylated C1-C5 alkyl, C1-C5 acyl; C2-C5 alkenyl, or a halogen atom; and k, l, and m are each an integer of 1 to 4.) Exhibiting excellent antifungal effect, these compounds are highly useful as antifungal agents, antifungal compositions, drugs, etc.

An amine dispersant containing one or more amino and/or imino groups, a poly(oxy-C.sub.1-6 -alkylene carbonyl) chain (POAC chain) obtainable from two or more different linear hydroxycarboxylic acids or lactones thereof and a residue of an ethylenically unsaturated group wherein the amino and/or imino groups are attached via the ethylenically unsaturated group. The POAC chain may be made from 2-hydroxyethylacrylate, .epsilon.-caprolactone and .delta.-valerolactone and the amine and/or imino group...

The present invention provides a compound represented by the formula ##STR00001## or salts thereof, wherein, Ar.sup.1, Ar, R, R.sup.1, R.sup.2, Ra.sup.1, Ra.sup.2, Ra.sup.3, Ra.sup.4 and Y have meanings described in the specification, having a melanin-concentrating hormone antagonistic, action and useful as an agent for the prophylaxis or treatment of obesity and the like.

This invention relates to the amine bisulfites which are useful as a combination corrosion inhibitor/oxygen scavenger. This is illustrated by heterocyclic amine bisulfites such as pyridine bisulfites.

A method of making (R)-N-[1-(3-methoxyphenyl)ethyl]-3-(2-chlorobenzene)propanamine which involves reducing the appropriate amidyl or iminyl precursor with an appropriate reducing agent. The appropriate amidyl or iminyl precursor is made from a synthesis involving the use of (R)-3-methoxy-.alpha.-methylbenzylamine. A method of condensing a nitrile with a primary or secondary amine to form an imine involves the reaction of a nitrile with diisobutylaluminum hydride; and then reacting the resultant ...

Novel amines of formula: where R is cis-2-phenylbicyclo[2,2,2]octane or 2-phenylbicyclo[2,2,2]oct-2-ene nucleus, n is 1 to 3, R.sup.1 is C.sub.1-3 alkyl and R.sup.2 is hydrogen or C.sub.1-3 alkyl, and acid-addition salts thereof, which are useful for the treatment of disorders of the central nervous system.

Four phenylethynyl amine compounds--3 and 4-aminophenoxy-4'-phenylethynylbenzophenone, and 3 and 4-amino-4'-phenylethynylbenzophenone--were readily prepared and were used to endcap imide oligomers. Phenylethynyl-terminated amide acid oligomers and phenylethynyl-terminated imide oligomers with various molecular weights and compositions were prepared and characterized. These oligomers were cured at 300.degree. C. to 400.degree. C. to provide crosslinked polyimides with excellent solvent resistance...
