摘要：
Disclosed herein is a preparation process for an indole, which process comprises subjecting an N-(.beta.-hydroxy)-alkylaniline, in the presence of a catalyst and at a super-atmospheric pressure, to a gas-phase catalytic reaction. The present process improves the selectivity of the reaction and the service life of the catalyst.
