Title:
CATALYST FOR VAPOR PHASE INTRAMOLECULAR DEHYDRATION REACTION OF ALKANOL AMINES
Document Type and Number:
Japanese Patent JPS63126556
Kind Code:
A
Abstract:

PURPOSE: To highly selectively convert alkanol amines to cyclic amines at a high yield by using a catalyst consisting of group IbWVIII transition metal elements, alkali metals and/or alkaline earth metals and specific bond of P, O.

CONSTITUTION: The titled catalyst is constituted of the catalyst compsn. expressed by the formula XaPbYcOd (X denotes 1 or more kinds of elements selected from the group IbWVIII tarnsition metal elements of periodic table Y denotes the alkali metals and/or alkaline earth metal, aWd denote atomic ratios of the respective elements, b=0.01W6 C=0.001W3 when a=1, d is the numerical value determined by the bonding condition of aWc and various constituting elements). The alkanolamines expressed by formula I (R, R' are selected from H, methyl groups and ethyl groups, n is an integer in a 2W5 range) are converted to the cyclic amines expressed by formula II (R, R' and n are the same as in formula I). As a result, the desired cyclic amines are highly selectively and stably produced at a high yield.
