Condensation product of p-Aminodiphenylamine sulphonic acid and 1-chloro-2:4-dinitrobenzene.

A lead-lined vessel of 4,500 litres capacity fitted with a leaden heater coil and reflux condenser is charged with 1,800 litres water and 90 kg. soda followed by 200 kg. p-Amino-diphenylamine sulphonic acid 100%. When this has dissolved, 153 kg. 1-chloro-2:4-dinitrobenzene is added, when the pan closed and heated to 95⁰C. for 4 – 5 hours.

The charge is blown into 1,000 litres water at 40⁰C. and the dyestuff precipitated with 1,500 litres saturated salt solution.  After stirring for 10 minutes with the salt, the agitator is stopped otherwise the crystals become very small and filter badly. Next day the batch is pumped (using Kreisel pumps) into a filter press, but not washed, and dried at 90 – 100⁰C

Yield = 400 kg. Amido Yellow E.

Notes:

Because of a tendency to explode, the product is not ground in a Perplex mill or disintergrator but in a ball mill and finished off in a “ Tiedke” mixer.

The resulting dyestuff is almost always rather redder and purer than type, due to the excellent quality of the p-Amino-diphenylamine sulphonic acid delivered from Wolfen. It is corrected to type shade by blending with some of the much greener and duller product obtained by a similar condensation with the inclusion of ¹/₂ to 1 kg. Copper Sulphate before heating.
