Abstract:
PROBLEM TO BE SOLVED: To provide a catalyst having excellent characteristics, and to provide a production method of an aromatic polyamine mixture. SOLUTION: The production method of an aromatic polyamine mixture comprises, for producing aromatic polyamine mixtures containing the compound of formula (I), reacting a compound of formula (IV) and/or a compound of formula (V) at 20-200°C in the presence of a heterogeneous inorganic catalyst selected from the following groups: (b) montmorillonite which is doped with at least one element of group 2, group 3, group 4, group 7 or group 13 or an oxide of lanthanide and may be acid-activated and (c) one or more sheet silicates having an acidity of ≥0.05 mmol/catalyst g at p K a =1.5 and selected from the group consisting of montmorillonite and sepiolite (these may be acid-activated) and attapulgite. Formula (I): H 2 N-A-CH 2 -B-NH 2 . Formula (IV): H-A-NH-CH 2 -HN-B-H. Formula (V): H-A-NH-CH 2 -B-NH 2 (Wherein, A and B are each independently a 1-4C phenylene group which may have 1-4 substituents selected from a 1-20C alkyl group and a halogen).

Abstract:
PROBLEM TO BE SOLVED: To electrochemically produce a crystalline porous organic metal skeleton material containing at least one of at least bidentate organic compounds which are coordinately bound to at least one metal ion, in a reaction medium containing the at least one of at least bidentate organic compounds. SOLUTION: At least one metal ion is provided in the reaction medium by the oxidation of one anode containing the corresponding metal. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a method of absorbing and/or storing gas. SOLUTION: Gas to be stored is brought into contact with an organometallic skeleton electrochemically manufactured under conditions suitable for absorption of the gas to carry out absorption of gas to the organometallic skeleton, and if appropriate, the conditions are subsequently changed so that release of the stored gas occurs.
