Definitions
- the present invention relates to a process for producing an ethylamine by reacting ethanol with ammonia, a primary amine or a secondary amine in the presence of hydrogen and a heterogeneous catalyst, the use of a new agent for the denaturation of ethanol and the thus denatured ethanol.
- the ethanol used can be produced synthetically, for example by hydration of ethylene.
- synthetic ethanol is biologically or biochemically, in particular fermentatively produced, so-called bio-ethanol, on. This is made from renewable sources and is therefore from ecological
- bio-ethanol sometimes has a cheaper price than synthetic ethanol.
- WO-A-05/063681 (BASF AG) relates to a process for preparing an ethylamine by reacting ethanol with ammonia, a primary amine or a secondary amine in the presence of hydrogen and a heterogeneous catalyst, whereby a biochemically produced ethanol (bioethanol ) in which sulfur and / or sulfur-containing compounds were previously depleted by contacting with an adsorber.
- bioethanol biochemically produced ethanol
