Acid Orange 33 (CAS 6507-77-3) stands out in the realm of dyes due to its distinctive chemical composition and excellent performance characteristics. At NINGBO INNO PHARMCHEM CO.,LTD., we believe in empowering our clients with comprehensive knowledge of the products they use. This guide delves into the key properties and usage of Acid Orange 33, a dye that consistently delivers vibrant and durable orange shades.

The molecular formula of Acid Orange 33, C34H28N4Na2O8S2, and its molecular weight of 730.72, indicate a complex organic structure that is responsible for its dyeing capabilities. It is classified as an acid dye, meaning it utilizes an acidic dyeing process. This involves the use of acidic conditions, typically achieved with acetic acid or formic acid, to protonate the fiber, allowing the anionic dye molecules to form ionic bonds. This method is particularly effective for protein fibers (wool, silk) and synthetic polyamides (nylon), where it yields brilliant and saturated colors.

When considering the application of Acid Orange 33, its fastness properties are paramount. Numerous studies and industry standards confirm its good performance in several key areas. Lightfastness, often rated on a scale of 1 to 8, typically falls within the 4-5 range for Acid Orange 33, indicating a good resistance to fading upon exposure to light. Washfastness and perspiration fastness are also critical, with ratings generally between 3-4, ensuring that colors remain stable through laundering and exposure to moisture. For manufacturers looking to buy acid orange 33, these reliable fastness ratings are a significant advantage.

The typical usage of Acid Orange 33 involves preparing a dye bath with a controlled pH, usually in the weakly acidic range (pH 3.5-7). The dye is dissolved in water and added to the bath, followed by the material to be dyed. The dyeing process often involves heating the bath to specific temperatures, promoting dye uptake and exhaustion. The specific dyeing parameters may vary depending on the fiber type, concentration of the dye, and desired shade, making it essential to consult technical data sheets for precise instructions.
