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 SiaXxYyOb wherein Si is silicon, X is at least one element selected from alkali metals and alkaline earth metals, Y is at least one element selected from B, Al, Ti, Zr, Sn, Zn and Ce, and O is oxygen; and the suffixes a, x, y and b represent the atomic ratios of the elements Si, X, Y and O respectively, and when a=1, x=0.005 - 1 and y=0 - 1, and b is a value determined by a, x and y.
