Abstract of the Disclosure A catalyst for the vapor phase intramolecular dehydration reaction of an alkanolamine represented by the general formula Image (I) wherein each of R and R' is selected from hydrogen, a methyl group and an ethyl group, and n is an integer of 2 to 5, to convert it into a cyclic amine represented by the general formula Image (II) wherein R, R' and n are as defined above. The catalyst is an oxide composition represented by the following formula XaPbYcOd wherein X is at least one element selected from elements of Group IIIA, elements of Group IVA, elements of Group VA, transition metal elements of Groups I through VIII, lanthanoid elements and actinoid elements in the periodic table, P is phosphorus, Y is at least one element selected from alkali metal elements and alkaline earth metal elements, O is oxygen, the suffixes a, b, c and d are the atomic ratios of the elements X, P, Y and O respectively, and when a=1, b=0.01 - 6 and c=0 - 3, and d is a value deter- mined by a, b and c and the state of bonding of the constituent elements.
