Basic orange dyes

Basic Orange 1 (130) (aniline coupled to 2,4-diamiaotoluene) and Basic Orange 2 (22) (aniline coupled to y -phenylenediamiae) are examples of amine salt type cationic azo dyes. The cation is formed by protonation under acidic conditions. Under neutral or alkaline conditions, these dyes behave more like disperse dyes. In 1988 the U.S. production of Cl Basic Orange 2 amounted to 132 tons. 

Size polymers on polyester can be determined by staining tests with Cl Basic Red 22, Cl Reactive Red 12, iodine/potassium iodide solution, or a mixed indicator. The extraction of size components and their determination in solution using a variety of reagents to give a characteristic coloration or a coloured precipitate has been described. Methods using fluorescence spectroscopy with a fluorescent cationic dye (e.g. Pinacryptol Yellow or Cl Basic Orange 14) were also described. 

The identification of anionic polyfacrylic acid) sizes can be carried out by staining with a fluorescent cationic dye (Cl Basic Orange 14) followed by spectroscopic measurement of excitation wavelength and fluorescence emission [195,196]. Such methods can also be used (with Cl Basic Orange 14 or Cl Basic Red 1) to detect and estimate carboxymethylcellulose, poly(vinyl alcohol) and starch derivatives [197]. 

The use of basic organic dyes for ion pair extraction-photometric determination has been described.87 After ammonia treatment, an orange-red color with CUS04 and H2O2 (Deniges) can be quantitated.88 A water insoluble violet complex (X max. 620 nm) with 2-picoline-Cu(II) has also been reported.89... 

The coupling of HPLC to a mass spectrometer (MS) has provided for the ultimate in detection systems in terms of sensitivity and versatility. Betourski and Ballard (227) have used the techniques of thermospray TSP-LC-MS and tandem LC-MS-MS to obtain positive-ion mass spectra of two cationic dyes, Basic red 14 and Basic orange 14. According to Yinon et al. (228), TSP-LC-MS has been found to be a suitable technique for the analysis of dyes. It is sensitive and specific, and the ionization process is soft. One of the drawbacks, however, is that one obtains... 

Acid Coupling Process. On the other hand, Chrysoidine Y [532-82-1] (22) (Cl Basic Orange 2 Cl 11270) is an example of a dye produced by acid coupling. Aniline, 9.3 g, is diazotized and the diazo solution is added to a solution of 11 g / /-phenylenedi amine in 200 mL water then the solution is made slightly acidic with hydrochloric acid. The reaction mixture is maintained with stirring until coupling is complete as indicated by spot test where, upon addition of an alkaline solution of 2-naphthol, there is no color change if the diazo is exhausted. The solution is warmed to about 60 °C. A concentrated solution of salt is added (about 120 g). The reaction mixture is then allowed to cool and the dye is filtered and dried. Reddish brown water-soluble crystals are obtained.

A basic azo dye having the molecular formula Ci4Hi4N3Na03S that is used chiefly as an acid-base indicator and of which the dilute solution is yellow when neutral and pink when acid. The structure of the methyl orange dye is given in Figure 6.4. 

The coupling of benzenediazonium chloride with m-phenylenediamine in acid medium gives Basic Orange 2 (Chrysoidine), a dye of limited use on textiles but of importance for coloring paper, leather, and woodstains. 

Related to the xanthene dyes are the acridines, azines, oxazines, and thiazines. Acridine Yellow results from the fusion of toluene-2,4-diamine with glycerin and oxalic acid, followed by oxidation with ferric chloride. Basic Orange 15 (Phosphine) is a by-product of the manufacture of Basic Violet 14 (Fuchsine) and is an acridine dye.
