Carboxymethylcellulose (KMTs, tsellyulozoglikolevy acid, [C6H7O2(OH) 3 - x(ОСН2СООН) x] n, where x = 0,08 - 1,5) — derivative of cellulose in which the karboksilmetilny group ( - CH2 - COOH) connects hydroxylic groups of glucosic monomers. Is weak acid, it is colourless. It is for the first time synthesized and patented by the German chemist Jansen in 1918. Appearance: light - beige crystal powder. rn (1% solution in water): 7,7. In the chemical, food and medical industry it is most often used as sodium salt — sodium - carboxymethyl cellulose (Na - carboxymethylcellulose) which aqueous solutions are viscous, possess pseudo - plasticity, and at some grades — thixotropy. Na - carboxymethylcellulose is applied as the plasticizer, thickener, resorbent. As thickener is part of tooth paste, foodstuff, cosmetics. It is applied in production of glue (for example, glue bustilat). Na - carboxymethylcellulose clay suspensions are used when drilling. Is part of detergents and fillers for cold accumulators. Qualitative test: IK - spectrophotometry.
