Definitions
- This invention provides an effective process for converting alcohols to an amine.
- This invention provides an effective process for converting alcohols to an amine, notably primary, with desired characteristics such as inexpensiveness, high selectivity and conversion.
- the reaction is performed in the presence of a low loading transition metal catalyst, notably noble metal-free metal.
- Heterogeneous catalyst used in direct amination reaction is very attractive technology nowadays for its ease of separation and recyclability.
- Rare earth oxides such as cerium oxide is always used in the catalytic amination reactions.
- WO15054828 A1 discloses cerium oxide is used as a support to noble metal in the direct amination reaction.
- US2013178656 reports a process for preparing secondary amines by aminating excess primary or secondary alcohols with primary amines in the liquid phase in the presence of copper-comprising catalysts.
- Said oxidic support could be aluminum oxides, silicon dioxide, titanium dioxides, zirconium dioxide, lanthanum oxide, molybdenum oxide, tungsten oxide or mixtures of these oxides. However, it only links to high copper loading alumina supporting catalyst.
- Ken-ichi Shimizu et al. ACS Catalysis (2013) , 3 (1) , 112-117 reports a noble metal-free catalytic system for synthesis of primary amines from alcohols and NH 3 by Al 2 O 3 supported Ni catalysts.
- Various Ni loadings were tested according to this paper (1-20%) and catalysts with 5wt%and 10 wt%are found to be optimal.
- US4209424 teaches a catalyst for implementing a process for manufacturing amines from alcohols is composed of an active element in the transition metals family uniformly combined with a refractory porous structure with a specific surface of between 10 and 300m 2 /g and with a pore diameter less than 5000 A, wherein the transition metal content represents 30-70%of the total catalyst weight.
- the catalyst and the process are specifically applicable to the ethanolamine-ammonia reaction with a view to producing ethylenediamine, piperazine, and useful byproducts and the conversion of reactant is not quite good.
