Embodiment 1
[0033] Preparation of bleached sumercane slag
[0034] Take 100G local waste sugar canesets, pulverized with a powder, and then add 3L deionized water soaked to remove water soluble impurities, then use a large amount of deionized water to clarify, then add 2 l pre-prepared 2 wt% NaClo. 2 After the solution was adjusted with 5% dilute hydrochloric acid, it was heated in a 70 ° C water bath for 2 h, which was used to remove lignin and bleached, and then washed to neutral with deionized water, then add 1L pre-preformed 4 wt%. NaOH solution, heat 2 h in an 80 ° C water bath to remove the hemicellulose, washed with deionized water to neutral, repeated 4-6 times, collect residue, dehydrated with ethanol, dry in an oven at 60 ° C More than 12h, the solid was 31.790 g, and 3.1 L of deionized water was added to the above pulverization, that is, the content of about 1% by weight of the bleached sucrose slag was obtained.

[0037] Preparation of Tempo Oxa Slag Cellulose Nanofilament
[0038] The 200 ml of the solid content of about 1 wt% bleached sumercane slag, 0.211 g of NaBr and 0.032 g of TEMPO were mixed and uniformly adjusted to pH ≈10 with 0.5 M NaOH solution, slowly dropped into 30 ml of active chloride ≥ 7.5% NaClo solution under ice bath. After the dropwise addition, the reaction was continued at room temperature for 6 h, and the pH was continuously adjusted with 0.5 M NaOH solution, so that it was kept weakly alkaline, and the reaction was filtered and filtered and filtered with deionized water and 0.5m hydrochloric acid alternately washed. The white powder was dried under an oven at 60 ° C to obtain a white powder 1.035 g, namely Tempo oxide residue cellulose nanofibril.
[0039] The product was infrared, X-ray powder diffraction and transmission electron microscopy analysis.

[0041] Preparation of α-蒎 lynyl buckola nanoculine
[0042] Add 100 ml of anhydrous ethanol and 40G SEO to 250 ml reaction flasks. 2 After half an hour, the ethanol was evaporated, the obtained white liquid was a tanite oxidant, and then 30 ml of 1,4-dioxane, formulated into a 1,4-dioxidin solution of selenate monoester. 54.03 g of an alpha-olene, 60 ml 1,4-dioxane and 1.0 g of terephin phenol were added to 250 ml of three bottles, raised the oil bath temperature to 65 ° C 1, 4 - The dioxane solution slowly added to the three flasks and continued to heat the temperature while controlling the drip acceleration, making it slightly faster than the distillate speed, and the oil bath temperature is maintained at 100 ° C after the drop is added until no distillate is generated. The recovery of the collet selenium was filtered, and 0.90 g of a distillate of 0.90 g of terephinol and 1.75 g sulfite was evaporated to evaporase. After adding sodium chloride, the fraction of sodium chloride w...
