Product use: This pigment is more yellow than Pigment Red 57: 1, called Warm Red, has high tinting strength and vividness, and is sensitive to acid / alkali. Used in printing inks, good solvent resistance and heat stability (200 ° C / 10min); used in water-based flexographic inks, molecular metal and base ink alkali agent to reduce stability; used in rubber and plastics, in HDPE Medium heat resistance 260 ℃ / 5min, can be used for food, cosmetics and medicine coloring. There are more than 130 brands on the market.

Synthetic principle: CLT-acid is added to an aqueous solution of hydrochloric acid, stirred overnight, cooled down the next day, and diluted. Sodium nitrite solution is added below the liquid surface to diazotize and diluted for future use. , Dilute, add diazonium salt suspension coupling under the liquid, stir, add dilute acetic acid, and filter; stir the obtained paste with water, dilute, and then add dilute acetic acid to make it acidic, add barium chloride boiling solution, and boil Color precipitation, filtration, and drying to obtain the product.
