Among the best-known nonderivatizing solvent systems is a combination between copper, alkali, and ammonia termed Schweizer s reagent. Solutions of cuprammonium hydroxide have been used for both analytical and industrial cellulose dissolution. Regenerated fibers with silk-like appearance and dialysis membrane have been (and partially continue to be) industrial products on the basis of cellulose dissolution in cuprammonium hydroxide. The success of this solvent is based on the ability of copper and ammonia to complex with the glycol functionality of cellulose as shown inO Fig. 11. Because of the potential side reactions (oxidation and crosslinking, Norman compound formation), alternatives to both ammonia as well as copper have been developed. Cuen and cadoxen are related formulations based on the use of ethylene diamine and cadmium, respectively. The various combinations of alkali, ammonia. [Pg.1485]

Figure 2.9 Structure of polysiloxanes (silicones), and polyethylene glycols. An inventory of all the compositions of this type of phase, used either for impregnation or bonding, would be lengthy. Treatment of the internal wall of a silica column with tetradimethylsiloxane will obtain a stationary phase bounded, polymerized and later reticulated. (The bonding resembles the fixing of indelible colours in order to create a brightly tinted fabric the colour contains an active site with which is able to attach itself, for example, to the alcohol functionality of cellulose on cotton fibres).

Other important secondary products of cellulose are esters and ethers. Esters can be used for fibers and films, but also for varnishes and molding materials. The most important representative of ether derivatives is carboxymethylcellulose, which has widespread applications as a thickener, binder, and graying inhibitor in detergents. Despite the versatile possibilities to derivatize cellulose, only 0.5% of worldwide felling is used for chemical refining. Detailed information about the fundamentals and functionalization of cellulose can be found in [12, 13]. [Pg.72]

What is the function of cellulose in the human diet How does this relate to the structure of cellulose ... [Pg.513]

Arts. Yes. The physiological function of cellulose is that of a construction material for giving a plant its overall shape and physical strength. This requires physical strength which is not affected by water. [Pg.371]
