Given the increase in greenhouse gas emissions due to the use of fossil fuels, there is a need to develop renewable resources such as biomass as the feedstock for the chemical industry and as an energy source. In this context, bio-butanol has the potential to play a significant role for a sustainable chemical and energy industry [1]. 1-Butanol can be produced by biomass fermentation, with the ABE process; it was largely used during the first half of the last century. There is now a renewed interest, especially in the aim of producing 1-butanol as a biofuel or as a reactant for the synthesis of chemicals. In this communication, we report about the use of 1-butanol as the reactant for the synthesis of maleic anhydride. The reaction requires two steps, (a) the dehydration of 1-butanol into 1-butene, and (b) the oxidation of 1-butene into maleic anhydride. However, the two steps can be carried using a single bifunctional catalyst, possessing both acid and redox properties (one-pot reaction).

Abstract
Given the increase in greenhouse gas emissions due to the use of fossil fuels, there is a need to develop renewable resources such as biomass as the feedstock for the chemical industry and as an energy source. In this context, bio-butanol has the potential to play a significant role for a sustainable chemical and energy industry [1]. 1-Butanol can be produced by biomass fermentation, with the ABE process; it was largely used during the first half of the last century. There is now a renewed interest, especially in the aim of producing 1-butanol as a biofuel or as a reactant for the synthesis of chemicals. In this communication, we report about the use of 1-butanol as the reactant for the synthesis of maleic anhydride. The reaction requires two steps, (a) the dehydration of 1-butanol into 1-butene, and (b) the oxidation of 1-butene into maleic anhydride. However, the two steps can be carried using a single bifunctional catalyst, possessing both acid and redox properties (one-pot reaction).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
