METHOD FOR PRODUCING HYDROXYALKYLTRIETHYLENEDIAMINE HAVING IMPROVED HUE
-
Paragraph 0046; 0047, (2017/12/12)
PROBLEM TO BE SOLVED: To provide a production method which makes it possible to improve the hue of a cyclic alkanolamine such as a hydroxyalkyltriethylenediamine and efficiently obtain a high-purity bicyclic compound. SOLUTION: A method for producing the bicyclic diamine includes bringing a crude hydroxyalkyltriethylenediamine reaction liquid comprising a hydroxyalkyltriethylenediamine represented by formula (1) into contact with oxygen at 110-170°C and then distilling and purifying it (R1-R10 independently represent H, a C1-4 alkyl group or a C1-4 hydroxyalkyl group).

The method of manufacturing the amine compound Bicylic
-
Paragraph 0055; 0056, (2017/04/19)
PROBLEM TO BE SOLVED: To provide a method for simply obtaining a bicyclic amine compound at high yield and for suppressing by-product tar contents that may obstruct the continuous production. SOLUTION: The compound indicated by a formula (1) is subjected to intramolecular dehydration in a gas phase under the presence of a solid catalyst to produce the bicyclic amine compound indicated by a formula (2). In the formula (1), R1-R8each independently represents a hydrogen atom, a 1-4C alkyl group, a hydroxy group, a hydroxymethyl group or a 1-4C alkoxy group; X represents a carbon atom or a nitrogen atom; and Y represents a hydrogen atom, an alkyl group, a hydroxy group or a 1-4C hydroxyalkyl group. In the formula (2), R1-R8, X and Y are defined in the same manner as above. COPYRIGHT: (C)2012,JPOandINPIT
