Food Yellow 4:1 Usage And Synthesis
UsesFood Yellow no. 4 Aluminum Lake is a synthetic organic pigment. Dyes and metabolites, Environmental Testing.
Preparation4-Aminobenzenesulfonic acid?diazo, and 5-Oxo-1-(4-sulfophenyl)-4,5-dihydro-1H-pyrazole-3-carboxylic acid?coupled into aluminum salt deposit into color.
DefinitionChEBI: C.I. Pigment Yellow 100 is an organonitrogen compound and an organooxygen compound. It is functionally related to an alpha-amino acid.
General DescriptionYellow to greenish-yellow powder.
Air & Water ReactionsAzo dyes can be explosive when suspended in air at specific concentrations. Insoluble in water.
Reactivity ProfileFood Yellow 4:1 is an azo dye complex. Azo, diazo, azido compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class 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 HazardFlash point data for Food Yellow 4:1 are not available. Food Yellow 4:1 is probably combustible.
Flammability and ExplosibilityNot classified
Properties and Applicationsyellow. Yellow fine powder. Hardly soluble in water, oil and most organic solvents, but can be scattered, mixed with water, oil and other liquid and solid powder. Heat resistance, resistance to light sex, oil resistance, salt tolerance, C.I. Food Yellow 4 better than sex. The product is made of a certain amount of HCL again with phosphoric acid potassium hydrogen two solution diluted, the maximum absorption wavelength for 428 + 2 nm.
