Also known as cellulose methyl ether. Grey inner color fibrous powder, odorless and tasteless. swelling in water to form a clear or slightly turbid colloidal solution, which is insoluble in absolute ethanol, chloroform or ether. Molecular formula: [C6H7O2 (OH) 3] n. cellulose methyl ether is an alkaline cellulose produced by reacting cellulose with alkaline solution. The crude methyl cellulose can be prepared by reacting with methyl chloride under a certain pressure, and the powder can be prepared through the steps of separation, washing, drying, crushing, etc. ethyl cellulose aqueous solution is still stable after long-term storage, and has the property of anti mold growth. In the presence of concentrated peroxide, ethyl cellulose can be decomposed. ethyl cellulose in aqueous solution is not charged. The surface tension of its aqueous solution is lower than that of water, and it has good adhesion and dispersion. ethyl cellulose is widely used in various industrial fields. Because it can form a solution with high viscosity, surface tension is less than water, and has excellent wettability and dispersibility, it can be used as thickener, suspending agent, dispersing agent, etc. In addition, it can also be used as a film-forming agent and adhesive, as well as to prevent the penetration of animal, plant, and mineral oils, making it a oil-resistant surface treatment agent.
