How is hydroxymethyl cellulose made?

Carboxymethyl cellulose can be easily prepared from currently well-established processes. In fact, it is a new type of polymer compound produced by the chemical reaction of natural cellulose and caustic soda with chloroacetic acid. Of course, chemical reactions with these can bring by-products like sodium chloride and sodium glycolate, but these can also be used as chemical components, which can lead to very good by-product use and benefits. it will be better.

Characteristics and Synthesis of Hydroxypropyl Methyl Cellulose

Characteristics and Synthesis of Hydroxypropyl Methyl Cellulose

Hydroxypropyl methyl cellulose is refined from cotton after alkalization, using propylene oxide and methyl chloride as etherifying agents, through a series of reactions to make non-ionic cellulose mixed ether. Hydroxypropyl methylcellulose is a non-ionic cellulose ether, white in appearance, odorless and tasteless. The degree of substitution is generally 1.2-2.0. Its properties vary depending on the ratio of methoxyl content and hydroxypropyl content.

Production method of hydroxypropyl hydroxypropyl methylcellulose

Production method of hydroxypropyl hydroxypropyl methylcellulose

Treat the refined cotton cellulose with alkali solution at 35-40 ℃ for half an hour, press, pulverize the cellulose, and properly age at 35 ℃, so that the average degree of polymerization of the obtained alkali fiber is within the required range.
