CAS 3071-73-6

Acid black 24

Description:

Acid Black 24, with the CAS number 3071-73-6, is a synthetic azo dye primarily used in the textile industry for dyeing wool, silk, and nylon. It is characterized by its dark black color and excellent lightfastness, making it suitable for applications requiring durability. The dye is soluble in water, which facilitates its application in various dyeing processes. Acid Black 24 exhibits a strong affinity for protein fibers, allowing for deep and rich coloration. Additionally, it is known for its stability under acidic conditions, which is advantageous during dyeing. However, like many azo dyes, it may raise environmental and health concerns due to the potential release of aromatic amines upon degradation. Therefore, its use is often regulated in many countries. Safety precautions should be taken when handling this substance, as it may cause skin irritation or allergic reactions in some individuals. Overall, Acid Black 24 is valued for its performance in textile applications, but awareness of its environmental impact is essential.

Acid black 24, technical grade

CAS: 3071-73-6

Acid Black 24 is a hydroxylated fatty acid with the chemical name of 3-hydroxy-2,4,6-trimethylcyclohexanecarboxylic acid. It is a cross-linking agent for unsaturated polyester resins and an adsorbent for pollutants. The optimum concentration of Acid Black 24 varies depending on the type of polymerization and radiation used. For example, the optimum concentration for radiation at 25 degrees Celsius is 1.0%. The use of Acid Black 24 in wastewater treatment has been shown to reduce the amount of proton transport required by up to 50% and lower energy consumption by up to 80%.
