Food Yellow 4:1 Chemical Properties,Usage,Production

  • Preparation 4-Aminobenzenesulfonic acid?diazo, and 5-Oxo-1-(4-sulfophenyl)-4,5-dihydro-1H-pyrazole-3-carboxylic acid?coupled into aluminum salt deposit into color.
  • General Description Yellow to greenish-yellow powder.
  • Air & Water Reactions Azo dyes can be explosive when suspended in air at specific concentrations. Insoluble in water.
  • Reactivity Profile Food 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 Hazard Flash point data for Food Yellow 4:1 are not available. Food Yellow 4:1 is probably combustible.
  • Properties and Applications yellow. 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.
