An object of the present invention is to provide a technique for separation/collection of a lignin derivative which is useful for the separation of a lignin derivative having a 1, 1-diphenylpropane unit and/or a unit derived from the 1, 1-diphenylpropane unit from a mixture system containing the lignin derivative. In the Present invention, a lignin derivative having a 1, 1-diphenylpropane unit and/or a unit derived from the 1, 1-dipheylpropane unit is allowed to contact with a metal oxide in a liquid medium, thereby separating the lignin derivative in the form retained on the metal oxide.
本发明的目的是提供一种木质素衍生物的分离/收集技术,该技术有助于从含有木质素衍生物的混合物体系中分离出具有1,1-二苯基丙烷单元和/或由1,1-二苯基丙烷单元衍生的单元的木质素衍生物。在本发明中,让具有 1,1-二苯基丙烷单元和/或由 1,1-二苯基丙烷单元衍生的单元的木质素衍生物在液体介质中与金属氧化物接触,从而分离保留在金属氧化物上的木质素衍生物。
