Chementator: Heterogeneous catalyst

By Chemical Engineering |

A heterogeneous catalyst for producing the solvent methyl isobutyl ketone has been developed by graduate student Ferry Winter, who defended his chemistry Ph.D. thesis last month at Utrecht University (Netherlands; edlinks.chemengonline.com/5827-550). The catalyst is based on activated hydrotalcite — a layered clay composed of magnesium and aluminum hydroxides — which is deposited on carbon nanofibers. The catalyst can be used to make methyl isobutyl ketone from acetone and hydrogen, and is easily recovered from the product by filtration. Conventional production routes to the solvent are said to use homogeneous catalysts, which generate large volumes of waste streams and require additional purification steps to remove the catalyst from the product.   Click here for a full pdf version of the Chementator Section
