Synthesis and characterization of biobased epoxy monomers derived from d-glucose

Characterization of high glass transition temperature sugar-based epoxy resin composites with jute and carbon fibre reinforcement

“…As polymer matrix a novel, renewable, glucofuranoside based trifunctional EP monomer (GFTE) with 160 g/eq epoxy equivalent weight (synthesized and characterized previously by the research group of the authors [26,27]) was used. As reference resin conventional mineral oil based aromatic bifunctional DGEBA with 188 g/eq, aliphatic trifunctional glycerol (GER) with 144 g/eq and tetrafunctional pentaerythritol based (PER) with 168 g/eq epoxy equivalent weight were used, provided by IPOX Chemicals Ltd. (Budapest, Hungary).…”

“…In this study a newly synthesized high glass temperature glucose based (glucofuranoside based trifunctional epoxye GFTE) EP component [26,27] was tested as polymer matrix with amine and anhydride type curing agent. As reference resins, petrol oil based aromatic DGEBA, aliphatic glycerol based (GER e glycerol based epoxy resin) and pentaerythritol based (PER e pentaerythritol based epoxy resin) EP monomers were used as matrices.…”

Novel high glass temperature sugar-based epoxy resins: Characterization and comparison to mineral oil-based aliphatic and aromatic resins

“…As renewable epoxy resin components two glucosebased components, synthesized previously by the research group of the authors [37], were used: a solid glucopyranoside based trifunctional epoxy resin component (GPTE) and a liquid glucofuranoside based trifunctional epoxy resin component (GFTE). As conventional mineral oil based resins the bifunctional aromatic bisphenol-A based DGEBA and two aliphatic components, the trifunctional glycerolbased GER and the tetrafunctional pentaerythritolbased PER were used.…”

The Synthesis of Bio‐Based Flame‐Retarded Epoxy‐Precursors

“…The methyl‐α‐ d ‐glucopyranoside ( 1 ) was converted to the corresponding diallyl ether 5 in a two‐step synthesis as described by our research group . The benzylidene protecting group was then removed by treating intermediate 5 with 75% CH 3 COOH to obtain the methyl‐2,3‐diallyl‐α‐ d ‐glucopyranoside ( 6 ) [Scheme /(1)] …”

“…d ‐Glucose ( 7 ) was also converted to the corresponding triallyl‐ether bearing a benzylidene protecting group ( 8 ) according to the procedure described earlier . The treatment of 8 with 75% CH 3 COOH afforded the triallyl‐glucopyranoside ( 9 ) [Scheme /(2)] .…”
