CAS NO.9004-32-4 High Viscosity Thickener Carboxymethyl cellulose

Description:

Carboxymethyl Cellulose, CMC is a commonly referred to as food additive, its sodium salt (sodium carboxymethyl cellulose) as a viscosity agent is used, a paste.

Physical Properties:

Sodium carboxymethyl cellulose (CMC) is an anionic cellulose ethers, look for white or light yellow powder flocculent fiber powder or white, odorless, tasteless, non-toxic; soluble in cold or hot water, the formation of a certain viscosity transparent solution. The solution is neutral or slightly alkaline, insoluble in ethanol, ethyl ether, isopropyl alcohol, acetone and other organic solvents, soluble in ethanol or acetone solution of 60% water. Hygroscopicity, heat and light stability, the viscosity decreases with increasing temperature, and the solution stability PH value of 2 to 10, PH is less than 2, the precipitated solid, PH value is higher than 10 viscosity. Color temperature of 227 °C, carbonization temperature of 252 °C, 2% aqueous solution surface tension 71mn / n.

Chemical properties:

There are substituted carboxymethyl cellulose derivatives group, treated with sodium hydroxide to form alkali cellulose, cellulose acetate, then with a chlorine reaction. Glucose unit constituting the cellulose can be replaced with the three hydroxyl groups, the different degree of substitution of the product obtained. 1g dry weight per 1mmol carboxymethyl leaders who do not dissolve in water and dilute acid, but it can swell for ion exchange chromatography. Carboxymethyl pKa in water of about 4, about 3.5 of 0.5mol / L NaCl, a weak acid cation exchangers are usually at more neutral and basic pH4 for protein. More than 40% of carboxymethyl substitution of a hydroxyl group may form a stable water-soluble high viscosity colloid solution. Suitable for the processing of beverages
