Disperse Red 60
Disperse Red 60, or 1-amino-4-hydroxy-2-phenoxyanthraquinone, is a popular disperse dye of the anthraquinone Anthraquinone, also called anthracenedione or dioxoanthracene, is an aromatic organic compound with formula . Isomers include various quinone derivatives. The term anthraquinone however refers to the isomer, 9,10-anthraquinone (IUPAC: 9,10-dioxo ... family of dyes. It is a dark red solid that is insoluble in water but soluble in dichloromethane. Because Disperse Red 60 is produced on a large scale, its disposal or degradation has received considerable attention.{{cite journal, doi=10.1016/j.chemosphere.2004.07.030, title=Degradation of dyes in aqueous solutions by the Fenton process, year=2004, last1=Xu, first1=Xiang-Rong, last2=Li, first2=Hua-Bin, last3=Wang, first3=Wen-Hua, last4=Gu, first4=Ji-Dong, journal=Chemosphere, volume=57, issue=7, pages=595–600, pmid=15488921, bibcode=2004Chmsp..57..595X, url=http://ir.rcees.ac.cn/handle/311016/23586 References ...

Colour Index Numbers
Colour Index International is a reference database jointly maintained by the Society of Dyers and Colourists and the American Association of Textile Chemists and Colorists. It currently contains over 27,000 individual products listed under 13,000 Colour Index Generic Names. It was first printed in 1925 but is now published solely on the World Wide Web. The index serves as a common reference database of manufactured colour products and is used by manufacturers and consumers, such as artists and decorators. Colorants (both dyes and pigments) are listed using a dual classification which use the Colour Index Generic Name (the prime identifier) and Colour Index Constitution Numbers. These numbers are prefixed with C.I. or CI, for example, C.I. 15510. (This abbreviation is sometimes mistakenly thought to be CL, due to the font used to display it.) A detailed record of products available on the market is presented under each Colour Index reference. For each product name, Colour Index I ...

Disperse Dye
Disperse dye is a category of synthetic dye intended for polyester and related hydrophobic fibers. Disperse dyes are polar molecules containing anthraquinone or azo groups. It is estimated that 85% of disperse dyes are azos or anthraquinone dyes. History The history of disperse dye production is closely related to the synthesis of cellulose acetate fibres. Disperse dyes were invented in 1923-24. Fundamentals of dyeing Disperse dyes are non-ionic in nature and partially soluble in water. The interaction of dye molecule and polymer takes place with Van der Waals and dipole forces. Disperse dyes have better diffusion at boiling to a higher temperature. Examples * Disperse Orange 1 is an azo dye. * Disperse Red 9 is a red dye derived from anthraquinone. * Disperse Red 11, also called C.I. 62015 and 1,4-diamino-2-methoxy anthraquinone, is another anthraquinone dye. * Disperse Red 60 is also an anthraquinone dye. * Disperse Yellow 26 is a yellow disperse dye. * Disperse Yel ...

Anthraquinone
Anthraquinone, also called anthracenedione or dioxoanthracene, is an aromatic organic compound with formula . Isomers include various quinone derivatives. The term anthraquinone however refers to the isomer, 9,10-anthraquinone (IUPAC: 9,10-dioxoanthracene) wherein the keto groups are located on the central ring. It is a building block of many dyes and is used in bleaching pulp for papermaking. It is a yellow, highly crystalline solid, poorly soluble in water but soluble in hot organic solvents. It is almost completely insoluble in ethanol near room temperature but 2.25 g will dissolve in 100 g of boiling ethanol. It is found in nature as the rare mineral hoelite. Synthesis There are several current industrial methods to produce 9,10-anthraquinone: # The oxidation of anthracene. Chromium(VI) is the typical oxidant. # The Friedel-Crafts reaction of benzene and phthalic anhydride in presence of AlCl3. o-Benzoylbenzoic acid is an intermediate. This reaction is useful for produc ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
