Catalysts play a vital role in lowering activation energies for chemical reactions. This webinar provides further insights in the indexing and registration policies in CAS and Derwent files for some of the most common types of catalysts. Understanding the kinetics of how catalysts are captured in CAplus, Registry, CASREACT, MARPAT as well as DCR, DWPI and DWPIM provides a better search result. Search strategies demonstrate the most complete retrieval for organometallic as well as enzymatically catalyzed reactions but also for less well-defined catalysts like molecular sieves or zeolites. Moreover, the numeric property search being available in various databases helps to find further details around pore size, temperatures and other factors determining the efficiency of these catalysts.
