Biooxygenates Cross-coupling for Fuel Components Production

Abstract

C-C bond formation is a pivotal method to construct complex molecules from some simple substrates, with the electrophilic alkylation of a given starting material being one of the most useful procedures. The straightforward routes to the creation of a variety of alcohols having intricate structures through alkylation of simple alcohols remain very unusual. Previously we found that during heterogeneously catalyzed conversion of ethanol with iso-propanol 2-pentanol formed with the yield equal to 35 wt.%. The general co-products were 1-butanol, 1-hexanol and 1-octanol that are valuable chemicals itself. Here we propose a heterogeneously catalytic route to convert such fermentation products as ethanol, acetone, 2-propanol and 1-butanol obtained from a variety of renewable carbohydrate sources into precursors for petrol, diesel and jet fuels. One of the work features is the use of heterometallic precursors, containing different pairs of metals closer to a distance less than the sum of their covalent radii, for supported catalysts creation.Introdu
