Additives in Biphasic Hydroformylation: An Analysis of the Influence of the Interfacial Area

open access: yesChemie Ingenieur Technik, Volume 97, Issue 5, Page 378-394, May 2025.
Optimizing homogeneous biphasic hydroformylation offers significant potential for improving chemical efficiency by use of additives or by investigating different stirrer and reactor designs. Traditionally, efforts have focused on conversion rates and selectivity, but advanced techniques such as high‐pressure borescopy now allow detailed in‐situ ...

Isomerization and Hydroformylation of Long‐Chain Olefins Promoted by N^O Bidentate Rh(I) Catalysts Precursors Bearing Salicylaldimine and Naphthaldimine Supporting Ligands

open access: yesApplied Organometallic Chemistry, Volume 39, Issue 4, April 2025.
A series of Rh(I) complexes have been synthesized and characterized by NMR, IR, ESI‐Mass spectrometry and elemental analysis. The rhodium complexes were evaluated in the isomerization‐hydroformylation of internal and terminal olefins to linear and branched aldehydes.

Toward an improved causal test of network effects: Does alliance network position enhance firm innovation?

open access: yesStrategic Management Journal, Volume 46, Issue 4, Page 863-897, April 2025.
Abstract Research Summary Assessing whether network position causes firm outcomes is difficult because networks result from firms' strategic choices. To address this issue, we develop a research design that separates self‐driven network change from other‐driven change.

Raman Measurements in the Hydroformylation of Decene with Laser Powers of 1 mW in Ex Zones

open access: yesChemie Ingenieur Technik, Volume 97, Issue 3, Page 204-212, March 2025.
A Raman measurement system with an excitation power below 1 mW was developed for the measurement of the hydroformylation reaction of decene to undecanal. The Raman systems can meet the requirements for explosion protection while concentration differences can still be measured via sensitive detection.
