Abstract: Alcohols are prepared by the catalytic hydrogenation of the corresponding carbonyl compounds at elevated temperatures and at superatmospheric pressure in the liquid phase by a process in which the catalyst used contains copper on an SiO2-containing carrier in the presence or absence of one or more of the elements magnesium, barium, zinc and chromium.

Abstract: Aminoalkanol sulphuric acids, i.e. sulphuric acid monoesters of aminoalkanols are prepared by allowing an aminoalkanol and sulphuric acid to flow into a vigorously stirred suspension agent which agent is immiscible with water and is kept boiling at 70 DEG to 150 DEG C., the water formed in the reaction and any water supplied with the reactants being distilled off together with part of the suspension agent, the reaction being effected at atmospheric or subatmospheric pressure.
