A sustainable process for the hydrogenation of levulinic acid (LA) to γ-valerolactone (GVL) is reported. GVL can be easily obtained in high yield, adopting very mild reaction conditions, by an aqueous solution using a commercial ruthenium supported catalyst combination with heterogeneous co-catalyst, such as ion exchange resins Amberlyst A70 or A15, niobium phosphate, oxide. All hydrogenations were carried out at 70–50 °C and low hydrogen pressure (3–0.5 MPa). The most effective co-catalyst...
Levulinic acid (LA) is one of the top bio-based platform molecules that can be converted into many valuable chemicals. It produced by catalysis from renewable resources, such as sugars, lignocellulosic biomass and waste materials, attractive candidates due to their abundance environmentally benign nature. The LA transition niche product mass-produced chemical, however, requires its production sustainable feedstocks at low costs, adopting environment-friendly techniques. This review an...
The hydrothermal conversion of waste biomass to levulinic acid was investigated in the presence homogeneous catalysts. Different cheap raw materials (poplar sawdust, paper mill sludge, tobacco chops, wheat straw, olive tree pruning) were employed as substrates. yields improved by optimization main reaction parameters, such type and amount catalyst, temperature, duration, concentration, electrolyte addition. catalytic performances also adoption microwave irradiation an efficient heating...
Abstract A variety of measurements indicates that Au nanoparticle‐ catalyzed Sonogashira coupling iodobenzene and phenylacetylene is predominantly a heterogeneous process. Large gold particles are much more selective than small ones, which consistent with this view. Substantial leaching into the solution phase occurs during reaction, but resulting supernatant liquid exhibits immeasurably low catalytic activity; TONs for nanoparticles orders magnitude higher those leached Au, once pointing to...
A semiquantitative analysis by means of midinfrared FT-IR spectroscopy was tuned for the simultaneous determination cellulose, hemicellulose, and lignin in industrial crops such as giant reed ( Arundo donax L.) switchgrass Panicum virgatum L.). Ternary mixtures pure were prepared a direct correlation area/concentration achieved cellulose lignin, whereas indirect correlations found hemicellulose quantification. Good correspondences between values derived from our model those reported...
The hydrothermal conversion of giant reed (Arundo donax L.) to furfural (FA) and levulinic acid (LA) was investigated in the presence dilute hydrochloric acid. FA LA yields were improved by univariate optimization main reaction parameters: concentration catalyst, solid/liquid ratio mixture, hydrolysis temperature, time. catalytic performances adopting efficient microwave (MW) irradiation, allowing significant energy time savings. best further confirmed using a traditionally heated autoclave...
This paper deals with the characterization of magnetic iron oxide nanoparticles. Pure magnetite (Fe <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> O xmlns:xlink="http://www.w3.org/1999/xlink">4</inf> ) and noble metal doped were synthesized following a new sustainable microwave-assisted method. Furthermore, an experimental analysis was carried out to investigate chemical properties these nanopowders. Morphological characteristics pure...
A cascade strategy for the catalytic valorization of aqueous solutions levulinic acid as well γ-valerolactone to 2-methyltetrahydrofuran or monoalcohols, 2-butanol and 2-pentanol, has been studied optimized. Only commercial systems have employed, adopting sustainable reaction conditions. For first time, combined use ruthenium rhenium catalysts supported on carbon, with niobium phosphate co-catalyst, claimed hydrogenation acid, addressing selectivity 2-methyltetrahydrofuran. On other hand,...

Autohydrolyzed-delignified was employed as cheap cellulose-rich feedstock direct alcoholysis to n-butyl levulinate, adopting n-butanol green reagent/reaction medium, very dilute sulfuric acid homogeneous catalyst, and different heating systems. effect main reaction parameters give levulinate investigated check feasibility this identify coarse ranges...
In order to improve the lignin exploitation added-value bioproducts, a mild chemical conversion route based on electrochemistry was investigated.
The depletion of fossil resources is driving the research towards alternative renewable ones. Under this perspective, 5-hydroxymethylfurfural (HMF) represents a key molecule deriving from biomass characterized by remarkable potential as platform chemical. In work, for first time, hydrogenation HMF in ethanol was selectively addressed 2,5-bis(hydroxymethyl)furan (BHMF) or 2,5-bis(hydroxymethyl)tetrahydrofuran (BHMTHF) properly tuning reaction conditions presence same commercial catalyst...
