Document Type and Number:
Japanese Patent JP6862173
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a manufacturing method of an esterified cellulose nanofiber dispersion excellent in dispersibility and capable of manufacturing a film or the like having high transparency.SOLUTION: There is provided a manufacturing method of an esterified cellulose nanofiber dispersion having a process (A) for fibrillating anionic modified cellulose to obtain a dispersion of an anionic modified cellulose nanofiber, a process (B) for treating the anionic modified cellulose nanofiber with an organic onium compound to obtain an onium salt, a process (C) for dispersing a cleaned article, which the obtained onium salt is cleaned, in a solvent to obtain an onium salt dispersion, a process (D) for reacting the onium salt and an alkylating agent to obtain an esterified cellulose nanofiber, and a process (E) for dispersing the cleaned article, which the esterified cellulose nanofiber is cleaned, in the solvent to obtain the esterified cellulose nanofiber dispersion.SELECTED DRAWING: None
