Current situation and development trend of cellulose ether market

  Abstract: The production and consumption of hydroxymethyl cellulose and methyl cellulose and their derivatives were introduced, and the future market demand was predicted. The competition factors and problems in the cellulose ether industry were analyzed. Some suggestions on the development of cellulose ether industry in our country were given. Key words: cellulose ether; Market demand analysis; Market research   1. Classification and use of cellulose ether 1.1 Classification Cellulose ether is a polymer compound in which the hydrogen atoms on the anhydrous glucose unit of cellulose are replaced by alkyl or substituted alkyl groups. On the chain of cellulose polymerization. Each anhydrous glucose unit has three hydroxyl groups that can participate in the reaction if completely replaced. The value of DS is 3, and the degree of substitution of commercially available products ranges from 0.4 to 2.8. And when it's replaced by an alkenyl oxide, it can form a new hydroxyl group th...
