主な応用

Disperse Blue 14 is an important organic dye for the dyeing of polyester, vinegar and polyamide fibres and for transfer printing. It is also suitable for the manufacture of firework colouring components. It can also be used for surface colouring and plastics etc.

純化方法

Purify the anthraquinone by thin-layer chromatography on silica gel plates, using toluene/acetone (3:1) as eluent. The main band is scraped off and extracted with MeOH. The solvent is evaporated and the dye is dried in a drying pistol [Land et al. J Chem Soc, Faraday Trans 1 72 2091 1976]. It crystallises from n-butanol with m 221-222o and has max 539 and 644nm (EtOH). [Beilstein 14 H 198, 14 III 440, 14 IV 459.]
