BIOMASS-DERIVED EPOXY COMPOUND AND MANUFACTURING METHOD THEREOF |
摘要 |
There is disclosed a biomass-derived epoxy compound as an epoxidized product of a raw-material biomass-derived compound having a weight-average molecular weight of 300 to 10000. The biomass-derived epoxy compound has a weight-average molecular weight of 600 to 20000 and is soluble in an organic solvent for the preparation of a varnish. The epoxy compound is prepared by dissolving the raw-material biomass-derived compound in an aqueous alkali solution; adding epichlorohydrin to the solution and heating the mixture; and evaporating epichlorohydrin from the heated mixture and precipitating a biomass-derived epoxy compound, in which the aqueous alkali solution has a pH of 13.5 to 11.0. The biomass-derived epoxy compound has both high solubility in organic solvents and satisfactory heat resistance and can be manufactured in a high yield on the basis of the raw material through a less number of processes.
