Under the above reaction conditions, the conversion of 2-ethyl-2-hexenal and the yield of 2-EHO were 100% and 93.8%, … People, Search If you have a disability and experience difficulty accessing this content, contact Engineering Technology Services at, Find The copper chromite catalysts which are active for hydrogenation are very sensitive to sulfur poisoning. at a pressure of from 20 to 50 bar and a molar ratio of hydrogen : acetone equal to (1.5 to 1): 1. In addition, provide isothermal flow mode, enabling simplification of the kinetic evaluation of the experiments. Hydrogenation of hexanal to hexanol was studied over sulfided Ni-Mo catalysts supported on γ-Al2O3. Ni/γ-Al2O3 has good stability after calcination and reduction of the recovered Ni/γ-Al2O3. The result demonstrated that the main reason for the activity decline of the recovered Ni/γ-Al2O3 catalyst is that the surface Ni has been reoxidized to NiO. Hydrogenation of acetone is carried out in liquid phase for at least two stages at temperature from 60 o C to 140 o C and under pressure from 20 to 50 bars. It is a saturated fatty aldehyde, a n-alkanal and a medium-chain fatty aldehyde.
SUBSTANCE: method involves a stage of interaction of one or more α-halogenketones with general formula I , where each of "X" independently represents a halogen atom, except fluorine, a hydrogen atom and "Z" represents a halogen atom, except fluorine; with molecular hydrogen in the presence of heterogeneous catalyst, containing a transition metal, where the catalyst is a metallic salt, which is saturated with the catalyst carrier, where the metal consist of iridium, ruthenium or their mixture.

PM. It has a role as a human urinary metabolite. Hydrogenation of aldehydes resulting from the “Oxo” process is a reaction with important industrial applications. Using Nickel-containing catalyst (10% wt. The suitable reaction conditions for the hydrogenation of 2-ethyl-2-hexenal catalyzed by Ni/γ-Al 2 O 3 were obtained as follows: a weight percent of Ni/γ-Al 2 O 3 = 15%, a reaction temperature of 180 °C, a reaction pressure of 2.0 MPa and a reaction time of 80 min.
