Platinum is used in the following sectors of homogeneous catalysis:
Platinum (Pt)
Hydrosilations represent reactions to build up higher-molecular organosilicon compounds (silanes, siloxanes), and thus they are the basis of manufacturing silicones. Today silicone products are found all over the dental, automotive, building, polymer, or paper industries.
Platinum is the most effective metal for this homogeneously catalytic reaction. According to the purpose, it is mainly applied as "Speier's Catalyst", i.e. dihydrogen hexachloroplatinate(IV) hydrate ("CPA"), or in the form of "Karstedt's Catalyst".
Heraeus represents one of the most important partners to silicone industry for this type of homogeneous catalysis. Among the standard catalysts and precursors, we offer customized manufacturing of catalyst solutions ("Karstedt" types) on the basis of secrecy agreements.
Hydroformylation (oxo synthesis) is the conversion of alkenes into aldehydes with a mixture of carbon monoxide (CO) and hydrogen (H2), which is called "Synthesis Gas". In principle, hydroformylations based on platinum (Pt) are considerable, e.g. in the combination of dihydrogen hexachloroplatinate(IV) with tin(II) chloride (SnCl2). Low-valent rhodium represents the established catalyst metal.
Moreover, Heraeus manufactures new catalysts on a commercial scale and in strict confidence according to customers’ specifications.
