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. 

Dipping solution Dissolve 0.02 g acridine orange (Basic Orange 14, C.I. 46005) in 100 ml ethanol [3]. 

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 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...
