Selective and Flexible Transformation of Biomass‐Derived Platform Chemicals by a Multifunctional Catalytic System

Abstract

Eine nachhaltige Versorgungskette: Die kontrollierte Überführung der aus Biomasse erhaltenen Plattformverbindungen Lävulinsäure (LA) und Itaconsäure (IA) in die entsprechenden Lactone, Diole oder cyclischen Ether (siehe Bild) wird durch einen multifunktionellen molekularen Katalysator möglich.

Continuous flow nanocatalysis: reaction pathways in the conversion of levulinic acid to valuable chemicals

“…This compound seemed to be produced in our systems via a two step reaction from LA, first to AL and then subsequent hydrogenation to PDO (Scheme 3).These chemistries have also been previously reported to be catalysed by stabilised copper chromite materials. 8,20 AL can indeed be easily obtained by dehydration of levulinic acid at temperatures over 150ºC. 19 FA promotes this dehydration step even at lower temperatures in our proposed system.…”

“…8 Nevertheless, a quick check at reported catalysts, reaction conditions and processes clearly indicates that reported results to date can be optimised and catalytic systems should be carefully designed to minimise catalyst/metal loading maximisising at the same time MTHF yields from LA at the milder possible reaction conditions. MTHF is converted from LA in a multistep sequence (Scheme 1).…”

Beyond Petrochemicals: The Renewable Chemicals Industry

“…could be an interesting platform chemical for the production of polymers [15,16] as well as a central intermediate if the desired end products are hydrocarbons. [17] By removing oxygen in the form of fully oxidized species, such as carbon dioxide, which have no heating value, little energy is lost and the energy content of the product per carbon atom is effectively increased.…”

“…Recently, a large amount of research has gone into this approach. [15,16,35,36] Currently, the U.S. company Segetis has started up a process in which ketals are produced from the levulinic acid platform with a production of 136 t y À1 of levulinic acid ketals, with plans for a second plant. [37,38] Although no large-scale market currently exists for these ketals, they can possibly find use as nonpetroleum-based plasticizers and solvents and as polyols for polymer production.…”

Influence of the preparation method of sulfated zirconia nanoparticles for levulinic acid esterification

“…Valorization of lignocellulosic biomass by its transformation into valuable chemicals or liquid fuels has attracted great attention in recent years [1][2][3][4][5]. Levulinic acid (LA) is one of the promising platform molecules obtained from lignocellulosic biomass and used for the production of fuel additives, polymers and fine chemicals [6][7][8][9][10][11][12][13][14][15].…”
