The condensation of ethanol and ethylaniline was studied using alumina catalysts at 300 °C. The gel water of the alumina affects its catalytic activity. Maxima and minima in activity occur at gel water values corresponding to those previously found for the dehydration of ethanol and formic acid. There is no concurrent change in crystal structure of the alumina gel. The results suggest the initial dehydration of alcohol to ether followed by condensation of the ether and ethylaniline to give diethylaniline. It is concluded that the best and poorest spatial arrangement of ‘active points’ or adsorption spaces is established by the amount of residual gel water.
