Mechanoactivated Celite as a catalyst for C‒H bond perfluoroalkylation and other radical reactions

Angewandte Chemie International Edition, Accepted Article.
Herein we report that Celite (diatomaceous earth) commonly viewed as an innocent filter aid or support material, or Earth‐abundant, non‐toxic metal oxides are efficient mechanoactivated catalysts for arene and heteroarene C‒H bond radical trifluoromethylation and pentafluoroethylation, with the activity comparable with previously reported ...

Pine bio‐oil based biorefinery procedure for the production of antioxidants, acids, and sugars

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract In this study, a wood‐based biorefinery with Pinus halepensis biomass was developed to obtain acids, sugars, and antioxidants with high recovery yields. Pine wood residues from sustainable forest management are transformed into bio‐oil (BO) and separated into value‐added chemicals with an integrated and innovative methodology.

Development of a continuous intensified process for conversion of hemicellulose sugars into furans using an agitated cell reactor

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study addresses significant process challenges associated with the reactive nature of hemicellulose‐derived furan intermediates in aqueous mediums. A continuous agitated cell reactor was used to intensify the extractive reaction using methyl isobutyl ketone as an extractive phase to isolate in situ the furan products obtained by ...
