Acid Blue 145 Disodium 1-Amino-4- [ (4-Methyl-2-Sulfonatophenyl) Amino] -9,10-Dioxo-9, What is the production method of 10-Dihydroanthracene-2-Sulfonate?
Acid Blue 145, that is, disodium 1-amino-4- [ (4-methyl-2-sulfophenyl) amino] -9,10-dioxo-9,10-dihydroanthracene-2-sulfonate, is prepared as follows:
First take anthraquinone-1-sulfonic acid and p-toluidine-2-sulfonic acid in an alkaline medium and make them react with each other. This reaction requires careful temperature control, and the temperature should be raised slowly to reach an appropriate range, so that the two can be fully combined to form an intermediate product.
Then, the intermediate product undergoes further condensation reaction under specific conditions. During the reaction, the selection of solvent, the regulation of pH and the control of reaction time are all crucial. The purpose of this condensation reaction is to construct the core structure of the target product.
After the condensation reaction is completed, the product still needs to go through the steps of separation and purification. The product can be precipitated from the reaction system by means of filtration and crystallization to remove impurities and improve the purity of the product. During the crystallization process, factors such as the type of solvent and the rate of change of temperature have a great influence on the crystalline morphology and purity of the product.
Compound with an appropriate sodium salt to introduce sodium ions, and finally obtain the final product of acid blue 145. The conditions of this salt-forming reaction also need to be precisely controlled to obtain the ideal yield and purity. In this way, after various steps, acid blue 145 can be obtained.

Acid Blue 145 Disodium 1-Amino-4- [ (4-Methyl-2-Sulfonatophenyl) Amino] -9,10-Dioxo-9, 10-Dihydroanthracene-2-Sulfonate What are the precautions during use?
Acid Blue 145, that is, disodium 1-amino-4- [ (4-methyl-2-sulfophenyl) amino] -9,10-dioxo-9,10-dihydroanthracene-2-sulfonate, this is an important dye. During use, be sure to pay attention to the following ends:
First, it is related to safety protection. This dye may be irritating, and protective measures must be taken when contacting. Operators should wear appropriate protective clothing, gloves and goggles to prevent the dye from touching the skin and eyes. In case of accidental contact, rinse with plenty of water immediately, and seek medical treatment if necessary.
Second, about storage conditions. Store it in a cool, dry and well-ventilated place, away from fire and heat sources. Avoid mixing with oxidizing substances to prevent chemical reactions that can cause dye deterioration.
Third, involving usage specifications. Use strictly according to product instructions and operating procedures, and precisely control the dosage. Too much dosage or cause too dark color and waste of dye, and too little will be difficult to achieve the expected dyeing effect. At the same time, pay attention to the temperature, pH value and other factors of the dyeing environment, which have a great impact on the dyeing quality. Different fiber materials have different affinities to the dye. Before use, you should fully understand and adjust the dyeing process accordingly to achieve the ideal dyeing effect.
Fourth, pay attention to environmental protection considerations. The wastewater generated during use, or containing the dye components, should be properly disposed of. It should not be discharged at will. It needs to go through a professional sewage treatment process and meet the discharge standards before it can be discharged to avoid pollution to the environment.
