Hydroxymethyl cellulose sodium

                                                           Hydroxymethyl cellulose sodium

Alkali cellulose was treated with sodium hydroxide cellulose, and then mixed with monochloroacetic acid sodium, the crude products, and then refined to finished product, is the hydroxymethyl cellulose sodium

Soluble in hot and cold water is good. Aqueous solution viscosity. Viscosity and degree of solubility and replace. Stable solution in pH2 ~ pH10 scope, pH2 below solid precipitation, pH10 above viscosity reduced rapidly.

Alkali cellulose was treated with sodium hydroxide cellulose, and then mixed with monochloroacetic acid sodium, the crude products, and then refined to finished products.

The nature of the
Aqueous solution viscosity. Viscosity and degree of solubility and replace. Stable solution in pH2 ~ pH10 scope, pH2 below solid precipitation, pH10 above viscosity reduced rapidly. Hydroxymethyl cellulose sodium (NaCMC or referred to as CMC) is a kind of water-soluble cellulose ether, can make the most of the commonly used viscosity of aqueous solution preparation in a couple of changes between cP to thousands of cP. NaCMC simplified formula is as follows: the Cell - O - CH2 - COONa NaCMC consists of a mutual reaction of chloroacetic acid and alkali cellulose. Alkali cellulose itself is composed of cellulose reacts with sodium hydroxide. Alkali cellulose steps to simplify the etherification agent and the reaction between cellulose chain is a must. Degree of substitution (DS) and the degree of polymerization (DP) is all levels of NaCMC typical indicators.
