The residual amount of TEMPO (2,2,6,6-tetramethylpiperidine oxide) in TEMPO oxidized cellulose nanofibers (TOCNF) is usually very low because TEMPO is usually removed thoroughly during production or Neutralize. To obtain high purity TOCNF, sufficient washing and separation steps are used in the production process to remove residual TEMPO and other reaction by-products (such as sodium bromate and by-product oxidants). Control of TEMPO residues When preparing TOCNF in industrial production and laboratory, the residue of TEMPO is usually controlled by the following methods: Multiple water washing and ultrafiltration: Multiple water washing can effectively remove residual TEMPO and reaction by-products, such as sodium bromate. and sodium bromide. Separation techniques such as ultrafiltration can further reduce the content of organic matter and small molecules in the solution. Neutralization and chemical reduction: In some processes, by chemical reduction or the addition of antioxidants, the T is

The application of nanocellulose in the field of Enhanced Oil Recovery (EOR) is mainly to improve the efficiency of the recovery process by utilizing its surfactivity, rheology regulation capabilities and nanoscale characteristics.
