Solvent Yellow 2 Chemical Properties,Uses,Production
Description
4-N,N-Dimethylaminobenzene diazonium chloride is a diazo compound found in diazo copy paper. It is allergenic only when unexposed.
Chemical Properties
yellow to orange crystalline powder
Uses
For determination of free HCl in gastric juice; spot test identification of peroxidized fats; pH indicator (red 2.9, yellow 4.0).
Preparation
aniline diazotization, and N,N-dimethylaniline coupling.
Production Methods
4-Dimethylaminoazobenzene was produced in large quantities in the early 1900s but is currently not produced in any significant commercial quantity in the United States.
Definition
A banned food coloring.
General Description
Yellow crystalline leaflets or an orange powder.
Air & Water Reactions
Dust may form an explosive mixture in air. Insoluble in water.
Reactivity Profile
Solvent Yellow 2 can detonate, particularly if sensitized by the presence of metal salts or strong acids. May form toxic gases 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. May form flammable gases with alkali metals. May react explosively with strong oxidizing agents, metal salts, peroxides, and sulfides. May react explosively with strong oxidizing agents, metal salts, peroxides, and sulfides.
Hazard
Carcinogen.
Health Hazard
4-Dimethylamino-azobenzene (XIII) is the parent compound of the amino-azo dye carcinogens; it is also known in the earlier literature as Butter Yellow, because it was used to color butter and vegetable oils before its carcinogenic activity was discovered. Many derivatives of XIII have been prepared and tested for carcinogenic activity. In the rat, the amino-azo dye carcinogens, administered in the diet, specifically induce hepatomas. Tumor induction by most of the amino-azo dyes is delayed or inhibited by high dietary levels of riboflavin (vitamin B2) or protein. Replacement of the –N=N– azo linkage by –CH=CH–, as in 4-dimethylaminostilbene (XIV), results in widening the target tissue spectrum; XIV induces tumors in the liver, mammary gland, and ear duct. Mice are much more resistant than rats to the carcinogenic activity of both amino-azo dyes and aminostilbenes.
Fire Hazard
Flash point data for Solvent Yellow 2 are not available. Solvent Yellow 2 is probably combustible.
Safety Profile
Confirmed carcinogen with experimental carcinogenic, neoplastigenic, and tumorigenic data. Poison by ingestion and intraperitoneal routes. Experimental teratogenic and reproductive effects. Human mutation data reported. When heated to decomposition it emits toxic fumes of NOx
Carcinogenicity
4-Dimethylaminoazobenzene is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity fromstudies in experimental animals.
Environmental Fate
Chemical/Physical. Releases toxic nitrogen oxides when heated to decomposition (Sax and
Lewis, 1987).
At influent concentrations of 1.0, 0.1, 0.01, and 0.001 mg/L, the GAC adsorption capacities
were 249, 140, 83, and 48 mg/g, respectively (Dobbs and Cohen, 1980).
Purification Methods
Crystallise the dye from acetic acid or isooctane, or from 95% EtOH by adding hot water and cooling. Dry it over KOH under vacuum at 50o. [Beilstein 6 IV 448.] CARCINOGEN.
