Title:
多糖類誘導体及びリグニン誘導体の製造方法
Document Type and Number:
Japanese Patent JP6799259
Kind Code:
B2
Abstract:
An object is to provide a method for producing a polysaccharide derivative without using a catalyst, a cocatalyst, or an active compound by esterification, etherification, or the like, from a polysaccharide such as cellulose as a source material, while maintaining a high molecular weight. Another object is to provide a method for producing a cellulose derivative in a separated condition directly from biomass containing lignocellulose. A method for producing a polysaccharide derivative of the present invention is characterized in that a reaction is carried out in a mixture comprising: a source material comprising a polysaccharide; an ionic liquid for which the pKa of a conjugate acid of an anion in DMSO is 12 to 19 and which is capable of producing a carbene; and a chain or cyclic ester compound or an epoxy compound. Preferably as a source material containing a polysaccharide, a biomass source material containing lignocellulose is used.
