| | Direct Brown 95 Usage And Synthesis |
| Uses | Direct Brown 95, Techincal Grade is an azo dye used in PET/cotton blended fabrics as well as other textiles. Environmental reproductive toxin.Environmental toxin on US EPA Toxic Release Inventory list (TRI) list. Dyes and metabolites, Environmental Testing | | Preparation | 4-(4-Aminophenyl)benzenamine double nitriding, first coupled with 2-Hydroxybenzoic acid, and then and 3-Amino-4-hydroxybenzenesulfonic aciddiazo, and Resorcinol coupling, in the form of complex copper a * single accidentally coupled nitrogen compounds. | | General Description | Dark brown microcrystals or charcoal black powder. | | Air & Water Reactions | Azo dyes can be explosive when suspended in air at specific concentrations. Slightly water soluble. | | Reactivity Profile | Direct Brown 95 is an azo compound. Toxic gases are formed by mixing azo compounds with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides. | | Fire Hazard | Flash point data for Direct Brown 95 are not available; however, Direct Brown 95 is probably combustible. | | Safety Profile | Low toxicity by
ingestion. Suspected carcinogen with
experimental carcinogenic and
neoplastigenic data. Mutation data reported.
When heated to decomposition it emits very
toxic fumes of Na2O, SOx and NOx. | | Properties and Applications | red light brown. Shallow brown powder. Soluble in water for orange brown, solubility of 35 g/L (80 ~ 85 ℃), slightly soluble in ethanol, insoluble in acetone. The strong sulfuric acid to red light purple, diluted into orange brown; In nitric acid for dark purple solution (don’t). The dye solution to join strong hydrochloric acid for brown, have precipitation; Join thin or thick sodium hydroxide solution for a red brown, precipitation. Dye cellulose fiber dyeing, dye devoured the gender is good, in the 100 ℃ temperature when the biggest affinity. Discharge the gender is good. Hard to sensitive. Dyeing copper and iron ions in a slight discoloration. Mainly used in viscose and their blended fabric dyeing and printing, and can also be used to knit fabric, blankets and silk, polyamide fiber fabric dyeing and printing, and can also be used in leather, paper and plastic color.
