Acid Blue 9 Chemical Properties,Usage,Production

Description

FD & C Blue No. 1 is principally the disodium salt of ethyl[4-[p- [ethyl(m-sulfobenzyl)amino]-α-(ο-sulfophenyl)benzylidene]2,5-cyclohexadien-l-ylidene](m-sulfobenzyl) ammonium hydroxide inner salt.
The colorant is a dark purple to bronze powder that dissolves in water to give a solution green-blue at neutrality, green in weak acid, and yellow in stronger acid. Addition of base to its neutral solution produces a violet color only on boiling. When dissolvedin concentrated sulfuric acid, it yields a yellow solution that turns green when diluted with water. It is soluble in 95% ethanol. FD & C Blue No. 1 is used in beverages and beverage powders, dairy products, bakery products, dessert powders, confectionery products, condiments, icings, syrups, jams, jellies, marmalades, liqueurs, and extracts. It is also used for coloring ingested drugs.

Chemical Properties

Blue powder

Uses

Acid Blue 9 (CAS# 2650-18-2) is an organic azo dye. It has been used in the preparation of solar-sensitive liposomes capable of capturing and releasing food dyes for the measurement of sunlight exposure over extended periods of time. Being water soluble, acid blue 9 is often considered a pollutant, and is used as an analyte in the development of azo-dye removal processes.

Definition

ChEBI: Erioglaucine A is an aromatic amine.

Preparation

2-Formylbenzenesulfonic acid ?and 3-(Ethyl(phenyl)amino)methyl)benzenesulfonic acid condensation, oxidation, and then the product into the ammonium salt or sodium salt.

Flammability and Explosibility

Not classified

Safety Profile

Human poison by intravenous route. Human systemic effects by intravenous route: muscle contractions or spasticity and dpspnea. Questionable carcinogen with experimental neoplastigenic and tumorigenic data. Mutation data reported. When heated to decomposition it emits very toxic fumes of NH3, NOx, and SOx.

Properties and Applications

colourful green light blue. Violet powder, soluble in water, in 90 ℃ water solubility of 50 g/L, soluble in ethanol. The strong sulfuric acid in orange, dilute yellowish later. The water solution is green light blue dye, add sodium hydroxide after it shows colorless, and you have a deep purple precipitation. Good levelness, white sex is better, for copper, iron ion sensitive, dyeing should pay attention, or influence colored light. This product used for wool, silk,nylon?with wool blended fabric dyeing and printing. Can also be used as a food dyes and organic pigments, also used for paper shading and anti-epidemic field, can also be used in leather color.
