Periodate oxidation of cellulose at elevated temperatures using metal salts as cellulose activators

Phosphonated nanocelluloses from sequential oxidative–reductive treatment—Physicochemical characteristics and thermal properties

“…Products were obtained at yield of 75-90%. As stated previously 120 (Sirvio et al, 2011), the decrease in the yield is due to the dissolution of hemicellulose (cellulose 121 pulp containing 24% hemicellulose). In addition, as a strong oxidant, periodate may also lead to 122 degradation of cellulose to some extent.…”

“…Highly crystalline NCCs are 53 traditionally produced using strong acids to dissolve the amorphous part of cellulose (Eyley and 54 Thielemans, 2014). Thus far, few alternative methods have been reported for NCC fabrication 55 The aldehyde contents of the oxidized celluloses were determined by an oxime reaction as 135 reported previously (Sirvio et al, 2011), while the amount of bisphosphonate groups was 136 calculated from the nitrogen content of the products, as determined with a Flash 2000 CHNS/O 137 elemental analyzer (Thermo Scientific, USA). 138…”

Preparation and chromatographic performance of a multifunctional immobilized chiral stationary phase based on dialdehyde microcrystalline cellulose derivatives

“…DMCC was prepared by selective oxidation of MCC with sodium periodate . First, 1 g of MCC was dispersed into 100 mL of deionized water.…”

Anionic wood nanofibers produced from unbleached mechanical pulp by highly efficient chemical modification

“…Unbleached spruce GWP was obtained in never-dried form, whereas the reference pulps (softwood dissolving cellulose pulp and hardwood bleached birch pulp) 16 were obtained as dry sheets. The materials were first disintegrated in water, filtered, washed with ethanol, and dried at 60 °C for 24 h. Imidazole, TEMACl, and succinic anhydride were purchased from TCI (Germany).…”
