Direct Blending Brown D-RS - Introduction
Direct blend brown D-RS is a dye, also known as direct cyan 35. It is an organic compound with a common chemical formula of C32H26N10Na4O10S2 and a molecular weight of 902.81g/mol. Its appearance is green powder.
Direct blended brown D-RS is a direct dye that can directly dye various textiles, such as cotton, linen, silk, wool, etc. It has good solubility and high hydrophilicity, can absorb light in a wide wavelength range, showing a bright brown.
The method for preparing directly blended brown D-RS generally adopts the method of chemical synthesis. Specifically, through appropriate reaction conditions, thiophenol and acetic anhydride react to generate thiophenol acetic anhydride, and then react with o-nitroaniline, after multiple chemical reactions and purification steps, the final direct blended brown D-RS is obtained.
safety information on the direct blended brown D-RS, it belongs to a class of low toxicity dyes. However, as with other dyes, care should be taken to avoid inhalation, contact with skin and ingestion to prevent possible irritation or allergic reactions. Wear appropriate protective equipment and follow relevant safety procedures during use. At the same time, the direct blend brown D-RS should be stored in a dry, cool place, away from fire and oxidizing agents. If inhaled or skin contact, should immediately rinse with plenty of water, and timely medical treatment.
