Hydroxypropyl methylcellulose: select highly pure cotton cellulose

Hydroxypropyl methylcellulose: select highly pure cotton cellulose Hydroxypropyl methylcellulose is a kind of cellulose whose output and consumption are increasing rapidly. It is a non-ionic cellulose mixed ether prepared by a series of reactions with propylene oxide and methyl chloride as etherifying agents after alkali treatment of refined cotton. The degree of substitution is generally […]
