Production Chart. CMC is produced from cellulose and monochloroacetic acid (MCA) and with sodium hydroxide (NaOH) as the third essential ingredient. The different steps in the CMC process are described in the flow sheet below. The cellulose is carefully selected to .
In order to generate carboxymethyl cellulose from the water hyacinth there are two main stages that is needed to be achieved (this include both physical and chemical reactions). The first procedure is initiated by obtaining the cellulosic parts of the plant and secondly derivate the cellulose obtained into carboxymethyl cellulose.

A binder is a chemical compounds that has an adhesive property, and is one of the more important excipients that are included in tablet formulations. In simple terms, binders or adhesives are the substances that promotes cohesiveness. A binder is therefore used for transforming powder into granules through a process known as granulation.

Manufacturing Process of sodium carboxymethylcellulose. General Introduction. sodium Carboxymethylcellulose is a kind of important cellulose gum, a polyanionic cellulose compound with good water solubility obtained from natural fiber by means of chemical modification.It is easily soluble in hot and cold water.
Disintegrants used in wet granulation include croscarmellose, sodium starch glycolate, sodium carboxymethylcellulose, polyvinylpyrrolidone (PVP), crospovidone, cation exchange resins, corn and potato starches, alginic acid and other materials that counteract the effect of binders and the physical forces of compression used in forming the tablets.
Jul 17, 1990· The energy consumption was about 40 kWh/t of cellulose. The temperature was 55° C. after the working. Subsequently, the ethanol contaning pulp was transferred into a reactor of kneader type for the preparation of sodium carboxy-methyl cellulose, which took place in a manner known per se to a person skilled in the art.

Cellulose is an organic compound with the formula (C 6 H 10 O 5) n, a polysaccharide consisting of a linear chain of several hundred to many thousands of β(1→4) linked D-glucose units. Cellulose is an important structural component of the primary cell wall of green plants, many forms of algae and the oomycetes.Some species of bacteria secrete it to form biofilms.

Cellulose Definition and Structure. Cellulose is a a largely indigestible polysaccharide (a complex carbohydrate), composed of thousands of glucose molecules [1].. Function. In the human intestine, cellulose acts as an insoluble fiber, which can absorb water and thus increase the bulk of the stool. Cellulose cannot be digested, but can be partly broken down (fermented) by beneficial large ...
Alpha-cellulose extracted from corn husks was used as the raw material for the production of food-grade carboxymethyl cellulose (CMC). Preparation of CMC from husk cellulose was carried out by an etherification process, using sodium hydroxide and monochloroacetic acid (MCA), with ethanol as the supporting medium.
