Identifying the best rhodium-modified catalyst and the best reaction conditions with ChemSCAN for the synthesis of aroma compounds
In the perfumery industry, there is a constant need to provide compounds imparting novel organoleptic notes. In this study, a ChemSCAN is used to investigate the hydroformylation of the substrate 4,4-dimethyl-1-vinylcyclohexyl acetate as a precursor for the desired 3-(cyclohex-1-en-1-yl)propanal derivative. Fast parallel trials allowed for the identification of the most active and selective modified rhodium catalyst. Subsequent concurrent experiments enabled the evaluation of different catalyst loadings and minimized the amount of solvent employed.
Investigating Zinc Oxide-Modified Mordenite as an Effective Catalyst for the Dehydrogenation of Ethanol utilizing the FlowCAT
In this study, the H.E.L FlowCAT was used for the development and optimization of a process for the production of acetaldehyde via the dehydrogenation of bioethanol. This is the first stage toward a multistep reaction, taking ethanol to higher-value chemicals.
Investigating a Sponge Metal Catalysts in a Trickle Bed Reactor for Continuous Hydrogenation Inflow
In this study, the H.E.L. FlowCAT was used to optimize the inflow of the reductive hydrogenation of an aliphatic nitro intermediate using a sponge nickel catalyst in a trickle bed reactor. Once optimal conditions were established, 1.2 kg of reagent was successfully reduced, with a yield of approximately 90% over a period of 19 hours.
Investigating Hydrogenations at Different Catalyst Loadings using the ChemSCAN
In this study, a ChemSCAN is used to investigate the hydrogenation of nitrobenzene with a range of Pd/C catalyst loadings ranging from 4.0 mg to 9.3 mg. The experimental results showed that the hydrogenation reaction rate increases as the amount of catalyst in the reactor increases.
