Patent number: 8617480Abstract: A concentrated acid treatment unit is composed of a reaction section and an agitation extraction section. A phenol sorped raw material obtained by defatting botanical resource-derived raw material by solvent to subject sorption phenols to sorption is introduced, thus obtaining mixed solution of phenol solution including a lignophenol derivative and concentrated acid solution including a cellulose hydrolysate. The reaction section agitates and mixes the phenol sorped raw material and concentrated acid to cause cellulose to be swollen to thereby convert lignin to lignophenol. A part of the cellulose is subjected to hydrolysis. The agitation extraction section receives the treated liquid sent from the reaction section and adds phenols for extraction thereto to cause lignophenol dispersed in the concentrated acid solution to be dissolved and extracted in phenols for extraction.Type: GrantFiled: October 21, 2009Date of Patent: December 31, 2013Assignees: Japan Science and Technology Agency, Kansai Chemical Engineering Co., Ltd.Inventors: Masamitsu Funaoka, Keigo Mikame, Hideo Noda

Patent number: 8012356Abstract: 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.Type: GrantFiled: June 6, 2006Date of Patent: September 6, 2011Assignee: Japan Science and Technology AgencyInventors: Masamitsu Funaoka, Mitsuru Aoyagi

Publication number: 20110196136Abstract: Provided is a Phase-Separation system plant for botanical resource, a conversion method, a concentrated acid treatment unit, and a concentrated acid treatment method by which lignin derivatives and hydrolyzed carbohydrate are manufactured out of a botanical resource efficiently and continuously. A concentrated acid treatment unit (3) is composed of a reaction section (20) and an agitation extraction section (25). A phenol sorped raw material (16) obtained by defatting botanical resource-derived raw material (15) by solvent (14) to subject sorption phenols (13) to sorption is introduced, thus obtaining mixed solution of phenol solution including a lignophenol derivative and concentrated acid solution including a cellulose hydrolysate. The reaction section (20) agitates and mixes the phenol sorped raw material (16) and concentrated acid (21A) to cause cellulose to be swollen to thereby convert lignin to lignophenol. A part of the cellulose is subjected to hydrolysis.Type: ApplicationFiled: October 21, 2009Publication date: August 11, 2011Applicants: JAPAN SCIENCE AND TECHNOLOGY AGENCY, KANSAI CHEMICAL ENGINEERING CO., LTD.Inventors: Masamitsu Funaoka, Keigo Mikame, Hideo Noda

Patent number: 7824577Abstract: The invention provides a polyaniline dopant which has small environmental load and from which an electrically conductive polyaniline having better processability on polyaniline can be obtained. A phenol derivative of lignin having a bis(aryl)propane unit in which a carbon atom on an ortho-position and/or a para-position relative to a phenolic hydroxy group of a phenol compound is bound to a carbon atom on a C1-position of an aryl propane unit of lignin is used as a polyaniline dopant. Since a phenol derivative of lignin is derived from a source that can be recycled, the dopant is a polyaniline dopant having small environmental load.Type: GrantFiled: March 10, 2005Date of Patent: November 2, 2010Assignee: Japan Science and Technology AgencyInventors: Masamitsu Funaoka, Mitsuru Aoyagi, Isao Murakumo
