Abstract:
An alicyclic polyamine of the formula (1) wherein Y1 represents a saturated aliphatic hydrocarbon group and R1 through R4 are the same or different and each represents hydrogen atom, an alkyl group, a cycloalkyl group, an aryl group, or an aralkyl group. The alicyclic polyamine can be obtained by subjecting a 3-formylcycloalkanone or 3-formylcycloalkenone to reductive amination reaction.
Abstract:
Alicyclic polyamines represented by general formula (1), wherein Y1 is a saturated aliphatic hydrocarbon group; and R to R are each independently hydrogen, alkyl, cycloalkyl, aryl or aralkyl. The polyamines can be prepared by reductive amination of 3-formylcycloalkanones or 3-formylcycloalkenones.
Abstract:

Abstract:
A nitrile compound or an amide compound is hydrolyzed in the presence of an inorganic acid or other acidic catalyst or an alkali metal hydroxide or other basic catalyst, and the by-produced ammonium salt of the acidic catalyst or the produced salt of a carboxylic acid and a base is electrodialysed to form an acid and ammonia or aqueous ammonia, or to form a base and ammonia. The obtained acid or base may be recycled as a catalyst for the hydrolysis of the nitrile compound or amide compound, and the obtained ammonia is reutilized as a nitrogen source for the nitrile compound or amide comound. Such amide compound may be produced by hydration of a nitrile compound in the presence of a manganese oxide.

Abstract:
PROBLEM TO BE SOLVED: To obtain a novel compound that is useful as a diamine component for thermoplastic and thermosetting polymers. SOLUTION: This compound is represented by formula I (Y1 is a saturated hydrocarbon; R -R are each H, an alkyl, a cycloalkyl, an aryl, an aralkyl), typically 3-aminomethyl-5,5-dimethylcyclohexylamine. The compound of formula I is prepared by catalytically reductive amination of 3-formyl-cycloalkanone or 3-formylcycloalkenone of formula II (Y2 is an aliphatic hydrocarbon) with at least one of ammonia, a primary and secondary amine in a hydrogen atmosphere in the presence of a hydrogenation catalyst in at least one kind of solvent.
Abstract:
PROBLEM TO BE SOLVED: To obtain the subject new compound useful as a polyhydric alcohol as a raw material for thermoplastic or thermosetting polymers. SOLUTION: This new compound is expressed by formula I [Y1 is a (substituted) saturated aliphatic hydrocarbon group, pref. a 2-8C alkylene], e.g. 3-hydroxymethyl-5,5-dimethylcyclohexanol. The compound of formula I is obtained, for example, by the following process: a 3-methylcycloalkanone or 3-methylcycloalkenone of formula II (Y2 is a hydrocarbon group) is oxidized (in an atmosphere of oxygen or oxygen-contg. gas, in a gaseous or liquid phase, pref. in the presence of a heteropoly-acid or its salt, at 50-200 deg.C) to form the corresponding 3-formylcycloalkanone or 3-formylcycloalkenone of formula III, which, in turn, is subjected to catalytic reduction pref. at 50-230 deg.C in the presence of a catalytically reducing catalyst such as a nickel compound or cobalt compound.
