Title:
THERMOSETTING RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2016/043218
Kind Code:
A1
Abstract:
A thermosetting resin composition according to the present invention comprises purified lignin and a lignin reactive compound that has a functional group capable of reacting with the purified lignin. Herbaceous biomass used as feedstock is processed in a first solvent which is a mixed solvent of water and at least one type of alcohol selected from aliphatic alcohols having 4 to 8 carbon atoms, after which alcohol is removed from the alcoholic phase that separates at a temperature at which the first solvent biphasically separates to obtain lignin. A second solvent which is an organic solvent alone or a mixed solvent of the organic solvent and water is added to the lignin, and purified lignin is obtained by removing the second solvent from the solution that is formed by dissolving the lignin in the second solvent. Condition A: Feed concentration of the feedstock with respect to the mixed solvent is 1 to 50 mass%. Condition B: The processing temperature is 100 to 350°C. Condition C: The processing time is 0.1 to 10 hours.
