Abstract
1,2-pentanediol (1,2-PeD) is widely used as a monomer for polyesters, as a key intermediate of low-toxic microbicides and is an ingredient of various cosmetic products. Nowadays, fossil non-renewable resources are the common basis for the production of chemicals and fuels. In this context, 1,2-PeD is currently produced via a cost-intensive multistep route by selective oxidation of pentene to pentene oxide and a subsequent hydrolysis. The displacement of exhaustible raw materials through biomass as a sustainable source of energy and organic carbon is clearly desirable. While the direct selective conversion of biomass into valuable chemicals is still a challenging research topic, various bulk chemicals like furfuryl alcohol (FA) are already available via established production routes. Since FA can be converted into 1,2-PeD by aqueous phase hydrogenolysis, it is representing a promising alternative and sustainable production route for 1,2-PeD. But so far most of the catalysts reported for the hydrogenolysis of FA are lacking of disadvantages either in regard of their toxicity (e.g. copper chromite), the need of additives or special solvents (e.g. adams's catalyst) or industrial applicability. In contrast to the aforementioned, supported ruthenium catalysts are non-toxic as well as stable against water under hydrothermal conditions. In order to assure high throughput and a constant product quality a continuous operation mode is clearly desirable for an industrial application. The trickle bed reactor is representing a promising concept due to its simple and robust build-up while exhibiting a good selectivity for the main products.
