HCID 49213192-Amino-4,6-dinitrophenol

Product 1

HCID 74754-Nitroaniline

Procedure

If, in Example 10, the 4,6-dinitro-2-amino-phenol is replaced by 12.3 parts of 2-methoxy aniline and the 4-nitro aniline by 30.9 parts of 4-amino-4'-nitro-diphenylamine-2'-sulphonic acid, one obtains a dyestuff which dyes leathers from different tanning processes in shades which are much more yellow.
