Usage And Synthesis
Outline

Methylcellulose ether, abbreviated MC, is a kind of long-chain substituted cellulose, in which 27% to 32% of the hydroxyl group exists in the form of methoxy. The substitution degree affects the physical properties of methyl cellulose such as solubility. Methylcellulose has an average molecular weight of 10,000 to 220,000. At room temperature, it exhibits as a white powder or fibrous material, and is non-toxic, non-irritating with non-allergic effect. Its apparent relative density is 0.35 to 0.55 (with the real density being 1.26 to 1.30). It swells in water into a translucent viscous colloidal solution which is neutral to litmus, insoluble in ethanol, ether and chloroforrm, but soluble in glacial acetic acid. It is tolerant to the effects of acid, alkali, microorganisms, heat, and light and is also not affected by oil and grease, but will burn upon reaching ignition point. Methyl cellulose is a product composed of cellulose glucose with all or part of three hydroxyls getting methylated. General products contain a methoxy fraction of 26% to 33% with degree of substitution being 1.7 to 2.2. Product with substitution degree being 1.3 to 2.6 is soluble in water, pyridinee, and acetic acid. This product is widely used for architecture, such as being used as the adhesive of cement, mortar, and for mudding off the seam. It is also used for making film an adhesive in cosmetics, medicine, and food industry. It can be also used as a textile sizing agents, synthetic resin dispersing agent, paint film formers and thickeners. The production method is that: use pulp to produce the alkali cellulose; alkali cellulose is reacted with methyl chloride or dimethyl sulfate in an autoclave and then further refined with warm water to obtain the final product.
