Research Topic

In terms of sustainability, selective conversion of renewable ressources, such as oleochemicals, is chemically feasible through the application of catalysts. Especially homogeneous catalysts are known to be highly selective at relatively mild reaction conditions. However, catalyst recycling is often challenging but of need to meet the requirements towards sustainability and be able to compete on industrial scale.

An approach for separation of products from the catalyst is crystallisation. The methoxycarbonylation towards linear diesters serves as a model reaction, since the product can be crystallised and filtered off from the catalyst solution. Effects on catalyst activity are currently under investigation.
