摘要：Cellulose nanofibers are produced by means of a method comprising a step (A)of oxidizing a cellulosic starting material in the presence of an N-oxyl compound and astep (B) of forming the oxidized cellulosic starting material into nanofibers by defibratingthe oxidized cellulosic starting material, and a step (C) of performing at least oneselected from the following steps: a step (C-1) of treating the cellulosic starting materialin water having a hydroxide ion concentration of 0.75 to 3.75 mol/L prior to performingthe step (A); and a step (C-2) of subjecting the oxidized cellulosic starting materialobtained from the step (A) to hydrolysis in an alkaline solution having a pH between 8and 14 after performing the step (A) and prior to performing the step (B).
