Corrosion inhibiting admixtures are unique among other methods to protect reinforced concrete from corrosion damage. In this study, the effect of furfural on fresh and hardened properties mixes 35 45 MPa compressive strengths as well inhibition was evaluated. Furfural added at different dosages (1, 2 3% by weight cement) with without superplasticizer (HRWR). Different electrochemical measuremen...

The present work was aimed at determining the feasibility of applying the extant kinetic technique to evaluate the ability of the biomass to degrade specific organic pollutants at full scale facilities and to determine the ability of these kinetic parameters to predict effluent concentrations of the target compounds. Biodegradation of acetate, ethylene glycol, acetone, and furfural was studied ...

Upgrading carbohydrate biomass is a promising process to convert low-value feedstocks into high-value chemicals and fuels, which critical for the development of sustainable renewable society. Among various conversion technologies, electrocatalytic methods have gained increasing research interest due their mild reaction conditions easy accessibility. Moreover, utilize water as green abundant sou...

Bio-oil produced from fast pyrolysis of biomass contains sugars originating from cellulose. Traditional quantification of sugars in bio-oil is accomplished by gas chromatography/mass spectroscopy (GC/MS) via derivatization, high-performance liquid chromatography (HPLC), ion-exchange chromatography (IC), or nuclear magnetic resonance (NMR) methodologies. These techniques are highly specific for ...

Levoglucosenone (1), a readily availabie carbohydrate from the pyrolysis of cellulose, has been attracting attention as a chiral starting material with multifunctional groups.i) Its unique structure, being highly oxygenated but with no hydroxy greups, provides a great advantage for multi-step synthesis. Levog[ucosenone (1) requires none of the protect]'ere-deprotection steps of hydroxy groups t...

Herein we report directed iridium-catalyzed C3−H silylation of furfuryl imines, which grants access to versatile synthetic platforms. This transformation was developed on derivatives, using imines as directing groups, and trialkylsilanes or bis(trimethylsilyl)methylsilane silylating agents, in the presence a hydride scavenger. Subsequently, fluoride-mediated activation strategies were applied C...

Furfural (FF) has a high potential to become major renewable platform molecule produce biofuels and bio-based chemicals. The catalytic performances of AuxPty AuxPdy bimetallic nanoparticulate systems supported on TiO2 were studied in base-free aerobic oxidation furfural furoic acid (FA) maleic (MA) water. characterization the catalysts was performed using standard techniques. optimum reaction c...
