CI Pigment Yellow 83 is a chemical compound from the group of the disazo and diaryl - pigments .
Extraction and presentation
Pigment Yellow 83 is produced industrially by tetrazotization of 3,3'-dichlorobenzidine , followed by azo coupling to the acetoacetylated chloro-4-2,5-dimethoxyaniline recovered.
properties
Pigment Yellow 83 is a flammable, hardly ignitable, yellow solid that is practically insoluble in water. It decomposes when heated above 300 ° C. It has a crystal structure with space group P 2 1 / c (space group no. 14) or space group Pc (space group no. 7) .
use
Pigment Yellow 83 is used as a reddish yellow pigment, for example for printing inks and plastics.
