Title:
ESTER-MODIFIED CELLULOSE NANOFIBER AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2020111673
Kind Code:
A
Abstract:
To provide a cellulose-based fiber capable of providing a resin composition which is excellent in compatibility with a resin when being blended with various resins, and can be produced at a comparatively low temperature and a low cost with less specification chemicals, and a resin composition containing the composite body.SOLUTION: There are provided a cellulose nanofiber having an ester group obtained by reacting cellulose having a carboxyl group or a cellulose nanofiber with alcohol, and a method for producing the same, in which an esterified cellulose fiber or a cellulose nanofiber is obtained by allowing cellulose fiber having a carboxyl group containing water or a cellulose nanofiber to form an azeotropic mixture with an organic solvent, dehydrating the mixture, mixing an organic acid and alcohol in the organic solvent to progress an esterification reaction and simultaneously removing the water purified by the esterification reaction by the azeotropy.SELECTED DRAWING: None
