Production and recovery system for furan compounds from rice straw using an ionic liquid (1-methylimidazolium hydrogen sulfate) and vacuum steam distillation

Autor: Kota Enomoto, Takashi Hosoya, Hisashi Miyafuji

Publikováno v: Journal of Wood Science, Vol 70, Iss 1, Pp 1-11 (2024)

Abstract Furan compounds, including 5-hydroxymethylfurfural and furfural, can be synthesized from biomass and have garnered attention for their potential applications in biofuels and resin precursors. In this study, the synthesis of the furan compoun

Fire and termite resistance of wood treated with PF6-based ionic liquids

Autor: Hisashi Miyafuji, Koji Minamoto

Publikováno v: Scientific Reports, Vol 12, Iss 1, Pp 1-10 (2022)

Abstract Six PF6-based ionic liquids (ILs) were investigated to evaluate their potential as chemicals for enhancing fire and termite resistance of wood. The ILs used in this study included 1-methyl-1-propylpyrrolidinium hexafluorophosphate ([MPPL]PF6

Production of 5-hydroxymethylfurfural from Japanese cedar (Cryptomeria japonica) in an ionic liquid, 1-methylimidazolium hydrogen sulfate

Autor: Ryoya Ito, Hisashi Miyafuji

Publikováno v: Scientific Reports, Vol 11, Iss 1, Pp 1-9 (2021)

Abstract Production of 5-hydroxymethylfurfural (5-HMF) from Japanese cedar (Cryptomeria japonica) using an ionic liquid, 1-methylimidazolium hydrogen sulfate ([MIM]HSO4), was investigated. 5-HMF can be produced from C. japonica at temperatures above

A Simple Method for Separating Lignin and Carbohydrates from Softwood Biomass in a Glass Tube using Tetra-n-Butylphosphonium Hydroxide

Autor: Hajime Yamada, Hisashi Miyafuji, Hiroyuki Ohno, Tatsuhiko Yamada

Publikováno v: BioResources, Vol 11, Iss 1, Pp 839-849 (2015)

The dissolving properties of softwood in an aqueous solution of the ionic liquid tetra-n-butylphosphonium hydroxide ([P4,4,4,4]OH) were studied. Cedar wood meal and 40% [P4,4,4,4]OH aqueous solution were mixed in a glass tube and treated at 121 °C a
