“…Final temperature of thermal destruction for CEC and AEC shifted to higher temperature and is 565 and 595 o C respectively. In the temperature range 400-450 o C the endothermic peaks are observed, which can be attributed to the formation of β-glucosan [27]. Figure 4 shows DTG curves for the same samples.…”

The main focus of this study is to investigate the influence of functional groups of cellulose and its derivatives on properties and morphology of alumina materials obtained by template synthesis. Cyanoethyl-, amidoethyl-and carboxymethylcellulose were synthesized from bleached softwood pulp and they were used as templates for alumina materials preparation. By means of methods of scanning electron microscopy and nitrogen physical sorption it was shown that properties and type of functional groups of template can influence on the morphology and textural characteristics of obtained ceramic materials. The alumina specimens that obtained from cyanoethyl-, amidoethylcellulose have thicker fibers and two times increased surface area in comparison with alumina obtained from initial cellulose but the one formed by carboxymethylcellulose have thin alumina fibers and three times decreased surface area. Thus, by regulating properties and type of template it is possible to obtain ceramic materials with desired properties and morphology.

“…(145) Cyanoethylation. One of the earliest examples of etherification of cellulose by an unsaturated compound through vinyl addition is the cyanoethylation of cotton (146). This base-catalyzed reaction with acrylonitrile [107-13-1], a Michael addition, proceeds as follows: For most textile uses, a DS < 1 is desirable.…”

Cotton is both a fiber and a food crop that is grown in about 130 countries in the world. About 60 countries cultivate at least 5000 ha and use about 2.5% of the world's total arable land area. In 2009/2010 in the world, about 103 million 217.7‐kg (480‐lb) bales [∼22.4 million metric tons (24.7 million tons)] of cotton fiber and 32.4 million metric tons (35.8 million tons) of cottonseed were produced. Cotton is the most important natural fiber (about 35% of the textile fiber consumed in the world in 2008) used to produce apparel, home furnishings, and industrial products. Cottonseed is one of the world's important oilseeds, used for vegetable oil, animal feed, and linters. About 95% of the world's cotton production is derived from varieties of upland cotton ( Gossypium hirsutum ) and about 5% is extra long staple cotton (“ELS”; G. barbadense ). In 2010 biotech varieties make up more than 60% of the cotton grown in the world. Commercial cottons are white. There has been some interest in organic cotton (∼0.6% of world production) and naturally colored cottons (shades of brown and green are the main colors; only a trace is produced). The demand for more “sustainable” / “ecofriendly” cotton and cotton textiles continues to increase. The origin, biosynthesis, biology, development, production, harvesting, ginning, classification, physical properties, textile processing, morphology, physical structure, chemistry, reactivity, economic aspects, utilization, and health and safety are reviewed.
