26. Metanilic Acid:

Manufacturing Process:

Stage-I: In a reactor Oleum (25%) is taken and Nitrobenzene is charged in it at

a controlled rate and temperature. After that drawn the sulfo mass in water. Add

lime slurry to neutralize the reaction mass. Filter the solution to remove gypsum.

Stage-II: In a reactor, a mixture of Iron & HCl (30%) is made. In that sulfo mass

is slowly added. Filter the ML & add H2SO4 (98%) to bring the pH 1.5. cool the

reaction mass, filter, centrifuge & get the final product.

28. Pigment Red 184:

Manufacturing Process:

Diazotization Preparation: Dissolve N-(3-amino-4-methoxyphenyl)benzamide

in water and hydrochloric acid, Stir it for 1 hour, cool it to - 5 ºC by cruising ice

Add rapidly sodium nitrite solution. Maintain temp below 10 ºC temp and stir for 1

hr. Filter it by press filter, Use it for coupling.

Coupler Preparation: Dissolve 5-Chloro-2-methylphenyl (3-hydroxynaphthalen-

2-yl) methanone in sodium hydroxide solution. Cool to 10 ºC temp.

Coupling: Add above prepared diazo solution in coupler solution with in about 1-2

hours. After complete addition pH is 3-4.During addition maintain temp 10-15 ºC,

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.
