The biphasic hydroformylation of 1‐octene using a lean aqueous phase as solvent phase for catalyst recycling is discussed here. The gas‐liquid‐liquid reaction was homogeneously catalyzed by industrial standard catalytic system with [Rh(cod)Cl]2 as precursor and TPPTS as ligand. This work summarizes investigations addressing different aspects of the reaction, where a procedural approach was followed to gain understanding of its nature, kinetics and interphase reactivity. Finally, the application of the jet loop reactor is analyzed as a means to intensify the reaction.

“…A further important point for the industrial feasibility of the process concept is the recycling of the homogenous catalyst in its active form [Schrimpf, M. et al 2019]. Very effective in this regard are water-based multiphasic systems combined with innovative reactor concepts for intensified mixing [Warmeling, H. et al 2017].…”

This paper introduces the work of the joint project "Robust and Efficient processes and technologies for Drop-In renewable FUELs for road transport" (REDIFUEL). The overall aim is to enable the utilization of various biomass feedstocks for an ultimate renewable EN590 diesel biofuel in a sustainable manner. REDIFUEL's ambition is to develop new technologies, solutions and processes to reach high conversion efficiencies for renewable fuel production. The proposed drop-in biofuel contains high-cetane liquid (C11-C21) bio-hydrocarbons and C6-C11 bioalcohols showing exceptional combustion and pollutant mitigation performance. Environmental and social aspects are also considered by carrying out a comprehensive Biomass-to-Wheel performance analysis. First artificial fuel samples simulating the final product have been synthesized and analyzed with regard to fuel relevant properties, showing very promising results.

“…As we have gained experience in both, aqueous biphasic hydroformylation 15,16 and in combining two or more catalytic transformations in a tandem (catalytic) system, 17 we now strive for the connection of hydroformylation and oxime formation in a one-pot approach (Scheme 1) using aqueous hydroxylamine. To achieve sufficient mixing and to ensure contact of the organic and the aqueous phase, the use of short-chain alcohols proved to be effective.…”
