C.I. Sulphur Brown 2 (8CI) Chemical Properties,Usage,Production
Preparation
The 4-Methylbenzene-1,3-diamine (2 Moore) and Oxalic acid (1 Moore) in 200 ℃ reaction, the condensation product with Sodium polysulfide in 220 ~ 300 ℃ calcination, until the happening of htdrogen sulfide to stop. Similar dye by (N-3-amino-4- methyl-phenyl) oxamate?and where did the 4-Methylbenzene-1,3-diamine etc molecular mixture, or with Phthalic acid, Succinic acid?or Mercaptoacetic acid?and Oxalic acid?instead of vulcanization.
Properties and Applications
dark yellow brown. In the Sodium sulfide solution good solubility.
