Usage

General Description

Disperse Orange 44 is a synthetic organic chemical compound that belongs to the class of azo dyes, which are widely used in the textile industry to impart color to various fabrics and fibers. It is known for its vibrant orange color and is typically used in polyester, acetate, and nylon fibers. Disperse Orange 44 is a relatively stable compound that can withstand high temperatures and has good lightfastness, making it suitable for use in outdoor and high-temperature applications. However, this chemical has been identified as a potential skin irritant and respiratory sensitizer, and it is important to handle it with caution and adhere to safety guidelines when working with it.

Stable diazonium salts of weakly basic amines—Convenient reagents for synthesis of disperse azo dyes

A new synthetic strategy for industrially important deep-shade disperse azo dyes was presented in this study. The key procedure is to prepare stable solid diazonium salts of weakly basic amines in the absence of concentrated sulfuric acid. Diazotization by tert-butyl nitrite in ethyl acetate was allowed to proceed in the presence of equivalent 1,5-naphthalenedisulfonic acid as stabilizer of diazonium salts and donor of hydrogen ion for the reaction. The separated solid diazonium salts exhibited good thermal stability. The corresponding disperse azo dyes were subsequently synthesized through the azo-coupling of the prepared solid diazonium salts with a range of aromatic tertiary amines. The azo dyes were produced in short reaction time, excellent yields, mild reaction conditions, simple experimental procedure and low energy consumption.
