Progress in development of epoxy resin systems based on wood biomass in Japan

Abstract

This article reviews the progress in the development of wood biomass origin epoxy resin system from 1960s to recent years in Japan. The methods of using wood biomass for epoxy resin systems are classified into the following three categories; one is the method of preparing lignin‐epoxy resins after applying treatments on the industrial lignin, which has been disposed in large volume, another is that of using wood as the raw material of epoxy resin system after applying treatments directly on wood, and the other is that of composing epoxy resin and/or curing agent from woody raw materials (except the industrial lignin), which are isolated and refined from wood before the treatments. Although several promising technologies have been developed and tried to be industrialized in Japan, the full‐fledged development of wood biomass‐based epoxy resin has just started when viewed as a whole. These developments will be further accelerated toward the construction of the environment harmony type and the resources circulation type societies. As the result of continuous developmental efforts, it is expected that we can look at the scene where epoxy resins are sustainably supplied in various forms even after the depletion of oil resources.

Characterization of fractionated biomass component and recovered ionic liquid during repeated process of cholinium ionic liquid-assisted pretreatment and fractionation

“…For the use of lignin as a raw material of resin, epoxy resin, and phenol resin have been intensively studied; in particular, epoxy resin prepared from either kraft lignin, a byproduct of the pulping industry, or lignin that has been fractionated via the pretreatment biomass processes such as steam explosion [33]. However, to the best of our knowledge, there are no reports of epoxy resin using lignin that has been fractionated from IL-pretreated lignocellulosic biomass.…”

The use of lipases as biocatalysts for the epoxidation of fatty acids and phenolic compounds

“…As an example, vanillin is obtained from the lignin sulfonic acid in sulphurous acid pulp waste liquor through the oxidation decomposition process in alkali solution. 142 Fig . 3 shows the synthetic method and the chemical structure of the di-functional epoxy resin derived from vanillin.…”

“…However, other hydroxyl containing compounds, including resorcinol, p-cresol, glycols and glycerol, can replace bisphenol A. [137][138][139][140][141][142] Another method consists of developing bio-based epoxy resins from pure phenolic compounds obtained through chemical treatment of lignin. As an example, vanillin is obtained from the lignin sulfonic acid in sulphurous acid pulp waste liquor through the oxidation decomposition process in alkali solution.…”

A chemical platform approach on cardanol oil: from the synthesis of building blocks to polymer synthesis

“…Most recently, much focus was put on biobased thermosetting resins such as epoxy resins, phenol resins, unsaturated polyesters and biocomposites. This is particularly due to their difficulty to be recycled owing to their infusibility and insolubilty (Koike, 2012). Literature reports very interesting pieces of works dedicated to the use of natural flavonoids (Benyahya et al, 2014) Correspondence: sylvain.caillol@enscm.fr or lignin-derivatives such as vanillin (Fache et al, 2014).…”
