ABSTRACT:
A lignosellulose-phenolic compound composite product having a weight ratio of the lignocellulose material to the phenolic compound of 0.4/1.0 to 5.0/1.0 is prepared by heat-dissolving the lignocellulose material in a solvent comprising, as a main component, at least one phenolic compound, optionally in the presence of a dissolving acid catalyst, and then adjusting the amount of the phenolic compound to a level of 1/0.4 to 1/5.0 of the weight of the lignocellulose material, in which heat-dissolving step water generated, as a by-product, from the reaction of the lignocellulose material with the phenolic compound is preferably eliminated, to allow the temperature of the reaction system to rise and thus promote the heat-dissolving reaction.
