Abstract
This invention relates to a process for the manufacture of dimethylethylamine comprising reacting gaseous ethanol with a gaseous mixture of hydrogen and dimethylamine in the presence of a hydrogenation/dehydrogenation catalyst comprising copper and chromic oxide alone or admixed with barium oxide, zinc oxide, magnesium oxide, or other oxides, at a temperature of about 180.degree. C. to 240.degree. C. and an absolute pressure of about 1 to 15 bars for a time sufficient to form dimethylethylamine, the molar ratio of dimethylamine/ethanol being about 0.2 to 0.6 and the molar ratio of hydrogen/ethanol being about 3 to 10.
