stir for 1 hr. At this temp heat the mass to 40 ºC and sodium acetate to get pH
4.0-4.5. The coupled pigment slurry is sent for further process.
Conditioning / Heating: Heat the mass pigment slurry to 90 ºC temp. Maintain
this temp. For 30 min. Cool to 70 ºC temp.
Filtration and washing: Filter the pigment slurry and wash with water up to salt
free. Filtrate and wash water are sent to ETP.
Drying and Packaging: Wet cake is then dried and pulverized. Then sent to
packaging.

33. Pigment Red 254:
Manufacturing Process:
Reaction: In SS reactor charge tert-amyl alcohol, p-chloro benzonitrile and
potassium tert-butoxide. The slurry is heated to 90 temperatures. To this mixture
slowly add solution of diisopropylsuccinate in tert-amyl alcohol. After complete
addition reaction mixture is heated to reflux for 2 hours. Cool it to 50 oC
temperature.
Isolation: At 50oC temperature add methanol. Stir for 30 minute for complete
isolation of product.
Filtration and washing: Filter the pigment slurry. ML is sent to solvent
recovery. Wash it with water. Wash water is sent to ETP.
Drying and Packaging: Wet cake is then dried and pulverized and then sent to
