Anthraquinone, with the CAS number 84 - 65 - 1, is an important organic compound. Its molecular formula is C₁₄H₈O₂, and it has a molecular weight of approximately 208.21 g/mol. This high - quality anthraquinone features excellent purity, ensuring reliable performance in various applications. It usually appears as a yellow crystalline solid, and has a melting point of around 286 °C and a boiling point of 379.8 °C at 760 mmHg. It is insoluble in water but soluble in organic solvents such as ethanol, benzene, and chloroform.
Anthraquinone has a wide range of applications. In the dye industry, it serves as a crucial intermediate for the synthesis of various anthraquinone - based dyes. These dyes are known for their excellent color fastness and vibrant colors, and are widely used in textile dyeing. In the paper industry, anthraquinone can act as a pulping additive. It can accelerate the delignification process, reduce the consumption of chemicals, and improve the quality of the pulp. Additionally, anthraquinone is also used in the pharmaceutical field. Some derivatives of anthraquinone have shown biological activities such as anti - inflammatory and antibacterial properties.
When using anthraquinone in the dye industry, it should be first dissolved in an appropriate organic solvent according to the specific dye - making process. The dosage needs to be strictly controlled based on the type of dye and the desired color effect. In the paper - pulping process, anthraquinone can be added to the pulping liquor at a certain proportion. Before adding, it is recommended to make a homogeneous solution to ensure uniform dispersion in the pulp. When using it in the pharmaceutical field, strict compliance with relevant pharmaceutical regulations and procedures is required. The compound should be processed and formulated under professional guidance to ensure its safety and effectiveness.
Textile Dyeing Case: A textile factory used our high - quality anthraquinone to produce a new type of blue anthraquinone dye. By precisely controlling the reaction conditions and the amount of anthraquinone added, they obtained a dye with excellent color fastness. The dyed fabrics passed various fastness tests, including rubbing fastness and washing fastness. This led to an increase in customer satisfaction and a boost in the factory's market competitiveness.
Paper Pulping Case: A paper mill introduced anthraquinone as a pulping additive. After adding an appropriate amount of anthraquinone to the pulping process, they found that the pulping time was significantly reduced, and the consumption of chemicals such as sodium hydroxide was also decreased. The quality of the pulp improved, with better strength and brightness, resulting in higher - quality paper products and cost savings.
