Abstract Valorization of lignocellulosic biomass, particularly catalytic hydrotreatment hemicellulose-based furfural (FUR), has been studied for the production value-added chemicals. A three-phase batch reactor used in isopropanol over various commercially available unsupported MoOx catalysts, at temperatures (170–230 °C), pressures (0–80 bar H2), catalyst loadings (0–2 wt%), and reactant conce...
Abstract Self-blowing lignin-furanic foams were produced using formulations comprising Kraft lignin and furfuryl alcohol as the major components. Diethyl ether, Tween 85 sulphuric acid used blowing agent, surfactant catalyst. The influence of components ratio to was investigated with regard foam density, mechanical properties, water absorption, thermal fire behaviour. Depending on formulation, ...
Furfural is a key bioderived platform chemical whose reactivity under hydrogen atmospheres affords diverse chemical intermediates. Here, temperature-programmed reaction spectrometry and complementary scanning tunneling microscopy (STM) are employed to investigate furfural adsorption and reactivity over a Pt(111) model catalyst. Furfural decarbonylation to furan is highly sensitive to reaction c...
The title compound, C(11)H(10)N(2)O(3)S, was synthesized from furoyl isothio-cyanate and furfurylamine in dry acetone. The thio-urea group is in the thio-amide form. The trans-cis geometry of the thio-urea group is stabilized by intra-molecular hydrogen bonding between the carbonyl and cis-thio-amide and results in a pseudo-S(6) planar ring which makes dihedral angles of 2.5 (3) and 88.1 (2)° w...
