Abstract: Synthesis of organic amines by condensation of organic hydroxy compound with ammonia or a primary or secondary amine in the presence of a rare earth metal hydrogen phosphate catalyst.

Abstract: A method for the synthesis of serinol and serinol derivatives substituted at the nitrogen atoms by reacting a lower 1,3-dialkoxy-isopropyl halide with ammonia or an amine to form a 1,3-dialkoxy-isopropylamine and then removing the ether groups by heating with a hydrogen halide acid. The method allows the production of serinol and serinol derivatives using inexpensive starting materials in a simple manner and obtaining a high purity product which is free of interfering isomers. Novel compounds obtained by the method which are useful as pharmaceutical intermediates, X-ray contrasting agents and cytostatic or psychopharmacological drugs are also disclosed.

Abstract: The present invention relates to a process for selectively preparing severely sterically hindered secondary aminoether alcohols by reacting a primary amino compound with a polyalkenyl ether glycol in the presence of a hydrogenation catalyst at elevated temperatures and pressures. The severely sterically hindered secondary aminoether alcohols are useful in acid gas scrubbing processes, particularly in the selective removal of H.sub.2 S from gaseous streams containing CO.sub.2 and H.sub.2 S.

Abstract: A process for the manufacture of methylamines comprises reacting a feed comprising methanol and/or dimethylether and ammonia over a binderless zeolite A catalyst, preferably a binderless zeolite 5A catalyst. Use of binderless zeolite 5A makes the process attractively selective to dimethylamine in preference to mono- and tri-methylamine. In addition, if the catalyst is essentially free of alkali metal it is not only more active than similar catalysts containing alkali metal but also considerably more selective.

Abstract: A process of preparing tris-(ether-amines) of the formula:N--[A--O--(B--O).sub.n --R].sub.3in which R represents a hydrocarbon radical, A and B represent alkanediyl radicals, and n is a whole number between zero and 4, by ammonolysis of an alkylene glycol mono-ether of the formula:HO--A--O--(B--O).sub.n --Rin the presence of 10 to 40 percent by weight of a hydrogenation-dehydrogenation catalyst, based on weight of said alkylene glycol monoether.The tris-(ether-amines) produced, such as tris-(3,6-dioxa-octyl)amine, tris-(3,6,9-trioxaundecyl)amine, tris-(3,6-dioxaheptyl)amine, and tris-(3,6-dioxadecyl)amine.

Abstract: In the catalytic preparation of methylamines from methanol and ammonia using an aluminosilicate catalyst, the mono-, di- and trimethylamine content of the product mixture can be varied from the equilibrium mixture ordinarily produced by using an amorphous aluminosilicate catalyst containing varying amounts of sodium, potassium, lithium, barium or strontium atoms as a result of treating an amorphous aluminosilicate with a corresponding metal hydroxide.

Abstract: In the catalytic preparation of methylamines from methanol or dimethyl ether and ammonia using a silica-alumina catalyst, catalyst coking and byproduct formation are reduced and reaction speed and catalyst thermal stability are enhanced when a catalyst containing a high level of alumina is used.
