Valorization of glycerol by ultrasound-assisted acetalization to solketal

Waste and Biomass Valorization
Abstract Conversion of glycerol into high-value chemical products is a compelling process in the biomass conversion and biorefinery industry. In this study, a novel approach was employed to investigate ultrasound-assisted solketal synthesis using glycerol and acetone as raw material and sulfated zirconia as catalyst.

Optimization of Saponification Process for Quantification of Individual and Total Tocopherols and Phytosterols in Canola Oil Refining By‐Products

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT In this study, saponification variables were optimized using a face‐centred central composite design‐response surface methodology. The variables included reaction temperature (50°C–120°C), reaction time (30–180 min), KOH concentration (0.5–3 M) and pyrogallol concentration (0–1% w/v).

Integrated biorefinery for cellulosic ethanol and spherical nanolignin production from coconut waste

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Green coconut waste was subjected to different fractionation methods to obtain integrated lignin nanoparticles and cellulosic ethanol. Pretreatment with gradual addition of dilute sulfuric acid provided a higher structural hemicellulose precursor yield (68.2%).
