Furfural is an important platform chemical with a wide range of applications. However, due to the low concentration of furfural in the hydrolysate, the conventional methods for furfural recovery are energy-intensive and environmentally unfriendly. Considering the disadvantages of pervaporation (PV) and distillation in furfural separation, a novel energy-efficient 'green technique', gas strippin...

Synthesis and characterization of 6-(hydroxymethyl)-14, 16-dimethyl-13, 14, 16, 17-tetrahydro-6H-13, 17-epiminodibenzo [e, l] [1, 4] dioxacyclotridecin-15 (7H)-oneABSTRACTNew 6-(hydroxymethyl)-14, 16-dimethyl-13, 14, 16, 17-tetrahydro-6H-13, 17-epiminodibenzo [e, l] [1, 4] dioxacyclotridecin-15 (7H)-one (2a) was synthesized in good yield by the Petrenko–Kritchenko reaction of 2, 2'-((3-hydroxyp...

Synthetic nanoporous carbons are prepared by polymerization of mixtures containing coal tar pitch and furfural in different proportions, followed by carbonization of obtained solid product and steam activation of the carbonizate. The chemical composition of the initial mixture significantly affects the physicochemical properties (surface area, pore structure, electro resistance and amount of ox...

5-Hydroxymethylfurfural (HMF) is a biobased platform chemical that can be valorized into spectrum of valuable products. In this report, supported Ir, Ir–Co, Ir–Ni, and Ir–Ru catalysts were investigated for purpose. Only hydrogenation HMF to 2,5-bis-(hydroxymethyl)furan (BHMF) occurred over all catalysts. The effect the second metal (Co, Ni, Ru) on Ir/SiO2 was reflected by kinetic constants bein...

For a multicomponent competitive adsorption of furfural and phenolic compounds, a mathematical model was builtto describe the mass transfer kinetics in a fixed bed column with activated carbon. The effects of competitive adsorption equilibrium constant, axial dispersion, external mass transfer, and intraparticle diffusion resistance on the breakthrough curve were studied for weakly adsorbed com...

The ingredients and the preparation methods influence biscuit quality safety. In Iraq, imports are increasing every year, but no information is available in scientific literature on their safety features. This work analyzed three types of biscuits (cookies, crackers, digestives) sampled Basrah markets (Iraq) produced Spain, Iran, Turkey, United Arab Emirates. Nine different brands were consider...

The present study investigated the possibility of spent coffee ground (SCG) transformation to a cellulose-based enzyme immobilization carrier using multistep extraction procedure. In first step, SCGs were extracted with n-hexane by Soxhlet in order obtain SCG oil, while remaining solid residue was subjected continuous solvent flow sequential subcritical 96% and 50% ethanol water. Afterwards, ob...

This work has established the optimum reaction conditions in a biphasic system using microcrystalline cellulose as the raw material, an ionic liquid as the solvent, metal chloride as a catalyst, and an organic solvent as the extraction reagent. The optimum reaction conditions were microcrystalline cellulose:ionic liquid 1:10 (mass ratio), chromium(III) chloride (CrCl3) 6.8 mol% (based on the gl...
