    Abstract: Indoles were prepd. by reacting aniline or its derivs. with 1,2- glycol under catalysts. Thus, a soln. contg. 30 g cadmium nitrate and 19 g 60%-HNO3 in 300 ml H2O was mixed with 130 g glass fiber contg. 29% SiO2 and 9% Na2O in 2 liters H2O to give a matrix (10-28 mesh; specific surface area=240 m2/g). This material was soaked in 25 wt.% AgNO3, dried at 80≦̸C, and reduced by boiling at 150≦̸C for 2 hrs. to give a catalyst. A mixt. contg. 7 M aniline and 1 M ethylene glycol was introduced into the reactor contg. a catalyst at the rate of 0.3 liter-mixt./1 liter-catalyst. At the same time, a mixt. contg. aniline and N2-gas (aniline; N2=1M:10M) was passed through the reactor. After reaction, the yield of ethylene glycol produced was 63% between 1 and 3 hrs. and 28% between 25 and 27 hrs.

    Abstract: SPECIFICATION Title of the Invention Process for the Preparation of Indole and Derivatives Thereof A process for the preparation of indole and derivatives thereof wherein an aniline is reacted with a 1,2glycol in the vapor phase, the liquid phase or a mixed vapor-liquid phase. A salt of a metal of group IIa of the periodic table, a salt of iron, a salt of cobalt and/or a salt of nickel are used as the catalyst for this reaction. The present invention makes it possible to prepare indole and derivatives thereof in a single step by using inexpensive compounds as the starting materials.
