Title:
METHOD FOR SEPARATION AND COLLECTION OF LIGNIN DERIVATIVE
Document Type and Number:
WIPO Patent Application WO/2006/132199
Kind Code:
A1
Abstract:
Disclosed is 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. 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.
