SUDAN ORANGE G Chemical Properties, Uses, Production
Chemical Properties
red-orange powder
Uses
Sudan Orange G is an oil soluble synthetic dye. Sudan Orange G can be degraded by a bacterial strain known as Pseudomonas putida MET94. Dyes and metabolites, Environmental Testing
Preparation
aniline diazo, Coupled with resorcinol.
Properties and Applications
bright orange. Yellow orange powder, melting point: 150 ~ 170 ℃ (usually products do not pure). Soluble in ethanol and aether (yellow), in the ethanol solubility of 0.2 ~ 0.3 g / 100ml, slightly soluble in water, but soluble in vegetable oil. The strong sulfuric acid to red light brown, for yellow brown solution diluted, and then into a dark orange precipitation; In 2% of sodium hydroxide solution (heating) for orange brown solution. Its water solution and strong hydrochloric acid color the darker, and then generate a shallow brown precipitation. Sun of resistance, alkali resistance is bad. And C.I.Solvent Orange 1the same chemical structure.
Purification Methods
Crystallise the dye from hot EtOH (charcoal). [Beilstein 16 IV 264.]
