Good heat resistance. Insoluble in acetone, slightly soluble in ethanol water, in concentrated sulfuric acid and concentrated sodium hydroxide have color change. |
| Use | The pigment is more yellow than pigment Red 57:1, which is called Warm Red, has high tinting power and brightness, and is sensitive to acid/alkali. Applied to ink, good solvent resistance and heat stability (200 C/10min); For water-based flexographic ink, molecular metal and base ink alkali agent to reduce the stability; For rubber and plastic, heat resistance in HDPE 260/5min, can be used for food, cosmetics and pharmaceutical coloring. There are more than 130 brands on the market. It is mainly used for coloring of ink, rubber products and bicycle inner tube. Also used for cultural and educational and plastic products coloring. The structure of rubber red LC is the same as that of gold Red C, but its synthesis process is to directly prepare Barium Salt Lake after coupling. The product is bright yellow and red, and the texture is soft. |

| production method | reaction equation reaction process: drain 2000L of water in a diazo barrel, add 3kg of pull-open powder, then add 50kg of 20% ammonia water, pour 119kg of CLT acid, slowly add 157kg of 30% hydrochloric acid under stirring to precipitate CLT acid in fine state, add and stir for 20min, the temperature is 10~12 ℃, and the body symbol is 500L, add 36.7kg of sodium nitrite at a temperature of 14~15 ℃, the solution remains acidic, and the end point is controlled to prepare coupling. Drain 1000L of water and 108kg of liquid alkali in the coupling barrel, raise the temperature to 60 ℃, stir and add 79.3kg of acetylnaphthol to dissolve, adjust the volume to 3500L, and adjust the temperature to about 30 ℃ for later use. Under good stirring, the CLT acid diazo liquid was quickly put into the coupling barrel, the end pH value was 10~11, the temperature was 28 ℃, the reaction was continued for 1h, and the pH value gradually decreased to 7.5~8. Add 13kg of rosin dissolved transparent solution with a pH value of 8.5~9. Dissolve 116kg of barium oxide in a certain volume and add it into a coupling barrel with a total volume of 8000 ~ 8500L and an end pH value of 8~8.5. Continue the reaction for 1h, quickly raise the temperature to 100 ℃, and keep the temperature for 1h. Filter, filter cake 80 ℃ for drying. The amount obtained is 255kg. |
