Melting point 239 °c. Excellent light resistance, heating at 150 deg C, heating 30Min has obvious darkening phenomenon. Excellent in acid resistance and alkalinity. But the pigment particles are harder. |
| Use | Used for printing ink, paint printing paste, latex, painting pigments, cultural supplies, such as coloring There are 21 kinds of the variety of formulations, given the red light yellow. The pigment is produced and used less in Europe and Asia, but more in the US market. Available with low surface area (6-20 m2/g) coarse particles, compared to C.I. Pigment yellow 83 Red slightly poor, high hiding power, good solvent resistance, light fastness, for air self-drying paint, latex paint, pigment printing paste; Due to low coloring strength and less for ink coloring. for oil medium latex coating, can also be used for paint, rubber and cultural goods coloring. |

| Introduction | yongguhuang RN is a brilliant red yellow pigment, which is slightly worse than the red light of yongguhuang HR, and has excellent hiding power and solvent resistance, red and yellow powder, more brilliant color. Melting point 239 °c. Excellent light resistance, heating at 150 deg C, heating 30Min has obvious darkening phenomenon. Excellent in acid resistance and alkalinity. But the pigment particles are harder. Yongguhuang RN is mainly used for the coloring of paint, ink, water-based paint, pigment printing paste, painting pigment, cultural and educational goods, rubber, plastic and other products. |
| Application | pigment yellow 65, there are 21 kinds of the varieties and formulations, giving red and yellow. The pigment is produced and used less in Europe and Asia, but more in the US market. Available with low surface area (6-20 m2/g) coarse particles, compared to C.I. Pigment yellow 83 Red slightly worse, high hiding power, better solvent resistance, light fastness, for air self-drying paint, latex paint, pigment printing paste; Due to low coloring intensity and less for ink coloring. For oil medium latex coating, can also be used for paint, rubber and cultural goods coloring. |
| Use | used in oil medium latex coating, can also be used in paint, rubber and cultural goods coloring. used for printing ink, paint printing paste, latex, painting pigment, cultural and educational supplies, etc. |
| production method | reaction equation operation procedure: weigh 10.3g of color base GP, grind into fine powder, add it to 100ml beaker, 13.0 of 36% hydrochloric acid and 30.0g of crushed ice were added thereto, and the mixture was stirred. Weigh 3g of sodium nitrite into 40ml of solution, then add 30.0g of crushed ice and stir. Weigh 4.3g of sodium nitrite into 40ml of solution, and then add to the color base GP suspension cooled to 0 ℃, and ensure that the excess solution of sodium nitrite is strongly acidic, carry out diazotization reaction, after adding the sodium nitrite solution, the reaction was continued at a temperature of 0 to 5 ° C. For 1H. After completion of the diazotization, the excess nitrous acid was destroyed with urea; The activated carbon was decolorized, filtered, and prepared for coupling. Weigh 12.5g of O-methoxyacetanilide, add 160ml of water to slurry, add 30% NaOH solution to dissolve it, and then adjust the pH value to 6.5~7 with glacial acetic acid to precipitate O-methoxyacetanilide, 20.0G of crystalline sodium acetate was added to the slurry and stirred. The prepared diazonium salt solution was added to the suspension of coupling components at 10-15 °c for about 20min, and the end point was controlled by the ring permeation experiment. After completion of the reaction, the pigment was obtained by filtering, washing with distilled water until the pH value of the filter cake was about 7.0 and drying at 80 °c. |
