On the occasion of their anniversary of “75 years of oxo synthesis”, Oxea and the Association of German Chemists (GDCh) recognized the pioneering work of Dr. Otto Roelen in the field of hydroformylation (oxo synthesis). The commemorative plaque displaying the words “Historical Landmark of Chemistry” was ceremoniously unveiled by the vice president of the GDCh, Prof. Dr. Michael Dröscher, at Oxea’s Ruhrchemie plant together with more than 100 guests from the industry, business and politics.
With this program, the GDCh honors achievements in chemistry of historical importance. As memorial sites, the places of work of those scientists involved are distinguished. “The discovery of the oxo synthesis by Roelen in 1938 was pioneering for the metal-organic chemicals industry and the application of homogenous catalysis on an industrial scale”, said Dr. Martina Flöel, spokeswoman for the executive board at Oxea.
In addition, the Fischer-Tropsch process, which was first used industrially by Roelen at the Ruhrchemie plant, and the large-scale manufacturing of high-molecular-weight polyethylene according to the method developed by Karl Ziegler were recognized.
