Abstract

A process for preparing ethylamines and monoisopropylamine (MIPA), in which bioethanol is reacted with ammonia in the presence of hydrogen and of a heterogeneous catalyst to give ethylamines, said bioethanol having a content of sulfur and/or sulfur compounds of ≧0.1 ppm by weight (calculated S), and then isopropanol is reacted with ammonia in the presence of the same catalyst and in the presence of hydrogen to give MIPA.
