Pigment Yellow 65 Use and Manufacturing

Methods of Manufacturing

Reaction equation Operating process Weigh 10.3g of color base GP, grind it into a fine powder and add it to a 100ml beaker, and add 13.0ml of 36% hydrochloric acid, while adding 30.0g of crushed ice, and stir. Weigh 4.3g of sodium nitrite to make a 40ml solution, then add 30.0g of crushed ice and stir. Weigh 4.3g sodium nitrite to make 40ml solution, and then add it to the color base GP suspension cooled to 0℃, and ensure that the excess sodium nitrite solution is strongly acidic, carry out the diazotization reaction, and add the sodium nitrite solution. Then, continue the reaction at a temperature of 0-5°C for 1 hour. After the diazotization is over, use urea to destroy the excess nitrous acid; decolorize the activated carbon, filter, and prepare for coupling. Weigh 12.5g of o-methoxyacetanilide, add it to 160ml of water to make a slurry, and add 30% NaOH solution to dissolve it, then adjust the pH to 6.5-7 with glacial acetic acid to make the o-methoxyacetoacetanilide precipitate, add crystals Sodium acetate 20.0g was beaten and stirred. The prepared diazonium salt solution was added to the coupling component suspension at 10-15°C for about 20 minutes, and the end point was controlled by the percolation experiment. After the reaction is completed, it is filtered, washed with distilled water until the filter cake has a pH value of about 7.0, and dried at 80°C to obtain a pigment.

Uses
