Abstract

A process for preparing a primary amine with a tertiary alpha-carbon atom by reacting a tertiary alcohol with ammonia in the presence of a heterogeneous catalyst, by performing the reaction in the presence of a non-microporous, non-zeolitic aluminosilicate as a catalyst, where the aluminosilicate has a molar Al/Si ratio in the range from 0.1 to 30.
