| Introduction | microcrystalline cellulose (MCC) is the product of acid hydrolysis of natural cellulose to the extreme degree of polymerization, its color is white or nearly white, odorless, tasteless, particle size is generally about 2~80 μm, has the advantages of small density, high modulus, renewable, degradable, wide source, etc, it can be used as a reinforcing agent of the composite material to improve the performance of the material. |
| properties | microcrystalline cellulose generally has a lower density in lyophilizers and a higher density in those using spray drying. The moisture content was about 5%. Microcrystalline cellulose can be dispersed but insoluble in water, insoluble in dilute acid, organic solvent and oil, swollen in dilute alkali solution, partially dissolved. The microcrystalline cellulose powder is dispersed in water to obtain a white transparent gel or paste, which is stable for many years except for the extremely dilute ones. |
| Application | microcrystalline cellulose is mainly used as non-caloric food additives, pharmaceutical excipients and dispersants, thin layer chromatography and column chromatography packing, colorants for dyes and pigments, reinforcing fillers for thermosetting resins and thermosetting laminates, coatings, emulsifiers, can also be used in the water-based paint and ceramic industries. |
| content analysis | accurately weigh a sample of 125mg, place it in a ML Erlenmeyer flask with about 25ml of water, 0.5 of 50.0 mol/L potassium dichromate was added and mixed. Sulfuric acid (100ml) was then carefully added and heated to boiling. The heat source was removed, allowed to stand at room temperature for 15min, cooled in a water bath and transferred into a 250ml volumetric flask. When diluted with water to near the scale, it was cooled to 25 °c and then allowed to volume with water and mix well. 50ml of this solution was taken, and 2-3 drops of phenanthroline test solution (TS-162) were added, followed by titration with 0.1mol/L ferrous ammonium sulfate. At the same time, blank titration was performed, and the concentration of ammonium ferrous sulfate, cmol/L, was determined according to the following formula: about 125ml of a sample was accurately weighed and transferred into a 300ml Erlenmeyer flask with about 25ml of water. 0.5 of 50.0 mol/L potassium dichromate solution was added and mixed. Sulfuric acid (100ml) was then carefully added and heated to boiling. The heat source was removed and allowed to stand at room temperature for 15min. After cooling in a water bath, one person was transferred to a 250ml volumetric flask. Dilute with water to approximately scale, cool to 25 °c, dilute with water to volume, and mix. Add 2-3 drops of phenanthroline test solution (TS-162) as indicator, Titrate with 0.1mol/L ferrous ammonium sulfate solution and record the consumed titration solution as S(mI). At the same time, a blank test was carried out, and the consumption of 0.1mol/L ferrous ammonium sulfate was recorded as B(m1). The percent cellulose (X) in the sample is then calculated as follows: X-(B-S) X 338/W where w is the mass (mg) of the sample and is corrected for loss on drying. |

| production method | cellulose is the most abundant natural polymer in the world, and its raw materials come from wood, cotton, cotton linter, wheat straw, straw, Reed, hemp, Mulberry, bark and bagasse. Due to the shortage of forest resources in China, 70% of cellulose raw materials come from non-wood resources. The average cellulose content of softwood and broad-leaved wood in China is about 43-45%, and the average cellulose content of straw is about 40%. The industrial method of cellulose is to cook plant raw materials with sulfite solution or alkali solution, which is mainly to remove lignin, which is called sulfite method and alkali method respectively. The resulting materials are referred to as sulfite pulp and alkaline pulp. The residual lignin is then further removed by bleaching and the resulting bleached pulp can be used for papermaking. Further, the hemicellulose is removed, and the hemicellulose can be used as a starting material for cellulose derivatives. α-cellulose is obtained by pulping fibrous plant material with inorganic acid to produce α-cellulose, and the cellulose is partially depolymerized by treatment, and then the non-crystalline part is removed and purified. The selected industrial wood pulp board is spliced out, and then sent into the reaction kettle with 1%~ 10% hydrochloric acid (the amount is 5%~ 10%) for temperature-rising hydrolysis, the temperature is 90~100 ℃, the hydrolysis time is 0.5~2H. After the reaction is finished, the reaction is sent to a neutralization tank by cooling, adjusted to Neutral with liquid alkali, filtered, and the filter cake is dried at 80~100 °c, and finally the product is obtained by crushing. cellulose made from wood or cotton pulp. It is refined after bleaching and mechanical dispersion. |
