Production of Alkyl Levulinates from Carbohydrate-Derived Chemical Intermediates Using Phosphotungstic Acid Supported on Humin-Derived Activated Carbon (PTA/HAC) as a Recyclable Heterogeneous Acid Catalyst
Autor: Nivedha Vinod, Saikat Dutta
Publikováno v: Chemistry, Vol 5, Iss 2, Pp 800-812 (2023)
This work reports a straightforward and high-yielding synthesis of alkyl levulinates (ALs), a class of promising biofuel, renewable solvent, and chemical feedstock of renewable origin. ALs were prepared by the acid-catalyzed esterification of levulin

Energy Densification of Biomass-Derived Furfurals to Furanic Biofuels by Catalytic Hydrogenation and Hydrodeoxygenation Reactions
Autor: Nivedha Vinod, Saikat Dutta
Publikováno v: Sustainable Chemistry, Vol 2, Iss 3, Pp 521-549 (2021)
The concomitant hydrolysis and dehydration of biomass-derived cellulose and hemicellulose to furfural (FUR) and 5-(hydroxymethyl)furfural (HMF) under acid catalysis allows a dramatic reduction in the oxygen content of the parent sugar molecules with

High-yielding synthesis of alkyl stearates from stearic acid within a closed batch reactor using heteropolyacids as efficient and recyclable catalyst
Autor: Sib Sankar Mal, Saikat Dutta, Ritesh Tiwari, Navya Subray Bhat, Nivedha Vinod
Publikováno v: NATIONAL CONFERENCE ON ENERGY AND CHEMICALS FROM BIOMASS (NCECB).
This study reports high-yielding and scalable synthesis of alkyl stearates from stearic acid (SA) within a closed batch reactor using commercially-available heteropolyacid catalysts. The reaction was carried out by using different commercially-availa

Hydrochloric acid-catalyzed coproduction of furfural and 5-(chloromethyl)furfural assisted by a phase transfer catalyst
Autor: Saikat Dutta, Sharath Bandibairanahalli Onkarappa, Navya Subray Bhat, Nivedha Vinod
Publikováno v: Carbohydrate Research. 496:108105
Furfural has been produced in 53% isolated yield from d -xylose within an aqueous HCl-1,2-dichloroethane biphasic reaction mixture using benzyltributylammonium chloride (BTBAC) as a phase transfer catalyst. The use of BTBAC noticeably improved the yi
