We have developed a kinetic model for aqueous-phase production of levulinic acid from glucose using a homogeneous acid catalyst. The proposed model shows a good fit with experimental data collected in this study in a batch reactor. The model was

Chemical communications (Cambridge, England), 48(29), 3497-3499 (2012-03-02)
Acid-catalyzed condensation of levulinic acid and phenol into high yields of diphenolic acid (>50%) is possible with a combination of sulfonated hyperbranched polymers and thiol promotors, either added as a physical mixture or bound to the polymer by ion-pairing.

Bioresource technology, 129, 616-619 (2013-01-23)
A highly selective approach to produce levulinic acid from cellulose was developed via microwave-assisted synthesis in SO3H-functionalized ionic liquids (SFILs). The effects of reaction conditions and ionic liquid structures on the yield of levulinic acid have been investigated, where the
Richard D Ashby et al.
Bioresource technology, 118, 272-280 (2012-06-19)
Glycerine (a biodiesel co-product) and levulinic acid (a pulp and paper co-product) were used as co-substrates for the fermentative synthesis of short-chain polyhydroxyalkanoate (sc-PHA) biopolymers with tunable monomer and molecular weight characteristics. Pseudomonas oleovorans NRRL B-14682 utilized glycerine alone to
Pierre Gallezot
Chemical Society reviews, 41(4), 1538-1558 (2011-09-13)
This critical review provides a survey illustrated by recent references of different strategies to achieve a sustainable conversion of biomass to bioproducts. Because of the huge number of chemical products that can be potentially manufactured, a selection of starting materials
