Abstract

New processes for the transformation of biomass into organic platform chemicals for the purpose of a material feedstock is in high demand. Deoxydehydration (DODH) is the reaction that transforms a vicinal diol into an alkene. Alkenes can be used as platform chemicals since it is a versatile molecule. This reaction requires a catalyst, stoichiometric reductant and solvent. Materials commonly used for this reaction are not sustainable nor eco-friendly, for example the most efficient catalysts for DODH are rhenium based. There is a need for catalysts that are cheap and abundant. Ammonium heptamolybdate (AHM) is a molybdenum based catalyst which is ten times less the cost when compared to rhenium. We are evaluating the use of AHM to catalyze DODH reactions using Na2SO3 as a cheap, readily available and benign reductant. Using 5 mol% of AHM and Na2SO3 as a reductant in toluene at 170°C, 1,2-decanediol was converted to 1,2-decene in 32% yield.
