CEMS graduate student Guarav Kumar’s research article selected as Editor’s Choice in Green Chemistry

Jan. 14, 2021 - Guarav Kumar, a fifth-year chemical engineering PhD candidate, had his research paper, “Dehydra-decyclization of 2-methyltetrahydrofuran to pentadienes on boron-containing zeolites” selected as an Editor’s Choice article in the journal Green Chemistry.

1,3-Pentadiene (piperylene) is an important monomer in the manufacturing of adhesives, plastics, and resins. It can be derived from biomass by the tandem ring-opening and dehydration (dehydra-decyclization) of 2-methyltetrahydrofuran (2-MTHF), but competing reaction pathways and the formation of another isomer (1,4-pentadiene) have limited piperylene yields to <60%. In this report, using detailed kinetic measurements of 2-MTHF dehydra-decyclization on zeolites with disparate acidities (boro-, and alumino-silicates) and micropore environments (MFI, MWW, and BEA), weakly acidic borosilicates were shown to exhibit ca. 10–30% higher selectivity to dienes at about five-to-sixty times lower proton-normalized rates than aluminosilicates (453–573 K).
