Sulfonic acid carbon-(bio)based and natural clays-based catalysts were prepared investigated for the first time as heterogeneous amide bond synthesis by a Ritter reaction. The different SO3H-catalysts screened using benzyl alcohol acetonitrile model substrates, MWCNT-CSP revealed to be an efficient catalyst, affording in 75 % yield. practical utility of was demonstrated diverse range amides, ob...

The sugar dehydration products, furfural and 5-(hydroxymethyl)furfural (HMF), are commonly formed during high-temperature processing of lignocellulose, most often in thermochemical pretreatment, liquefaction, or pyrolysis. Typically, these two aldehydes are considered major inhibitors in microbial conversion processes. Many microbes can convert these compounds to their less toxic, dead-end alco...

Bimetallic Ni-Cu/SiO2 catalysts with different Cu loading (2–5 wt%) were developed for liquid phase selective hydrogenation of furfural to furfuryl alcohol. Among these, bimetallic 2%Ni-X%Cu/SiO2 (X = 2, 5) exhibited better catalytic performances than monometallic 2%Ni/SiO2 and 2%Cu/SiO2. Moreover, the 2%Ni-5%Cu/SiO2 catalyst showed best performance 94% conversion 64% alcohol selectivity. The s...

Valorization of the abundant renewable lignocellulose through an efficient chemoenzymatic strategy to produce furan-based platform compounds has raised great interest in recent years. In this work, a newly prepared sulfonated tin-loaded rice husk-based heterogeneous chemocatalyst UST-Sn-RH was utilized transform corncob (75.0 g/L) into furfural (72.1 mM) at 170 °C for 30 min aqueous system. To ...

Twenty-four organic compounds currently undergoing testing within cancer bioassays under the aegis of the U.S. National Toxicology Program (NTP) were submitted to the computer automated structure evaluation (CASE) and multiple computer automated structure evaluation (MULTICASE) system for predictions of activity. Individual predictions resulting from the NTP combined rodent, NTP mouse, Carcinog...
