In order to prepare C.I. Acid Blue 140 (Disodium 4,4 '- [Methylenebis (4,1-Phenyleneimino) ] Bis [1-Amino-9,10-Dihydro-9,10-Dioxoanthracene-2 -Sulphonate]), many matters need to be handled with caution.
The quality of the first raw material. All the raw materials used must be selected with the best quality. Its purity and impurity content are all related to the quality of the product. If the raw material is impure and mixed into the reaction, the product will be impure, and the properties such as color light and fastness may be greatly affected. Therefore, when selecting materials, carefully check their specifications and quality inspection reports, and do not be perfunctory.
The reaction conditions are also very critical. Temperature is an item that must be precisely controlled. If the temperature is too high, the reaction will be too fast, or the side reactions will occur, resulting in the color and structure of the product. If the temperature is too low, the reaction will be slow, time-consuming and laborious, and the yield will be low. In different reaction stages, the temperature requirements vary, so be sure to adjust them carefully according to the process. In terms of pressure, if the reaction requires a specific pressure environment, when the holding pressure is stable, the pressure fluctuates or causes the reaction to be disordered.
The use of catalysts is also exquisite. An appropriate amount of catalyst can promote the reaction to go faster, but too much or too little is not appropriate. More catalysis is excessive, and side reactions increase; less catalysis is insufficient, and the reaction is stagnant. And different catalyst activities are different. Choose the appropriate one according to the reaction characteristics, and study its catalytic mechanism and dosage range in detail before use.
The cleaning and maintenance of the reaction equipment should not be neglected. The equipment is not clean, the old material remains, or the new reaction is introduced, resulting in the contamination of the product. Regularly clean the equipment to check its sealing and corrosion resistance, and ensure that the reaction environment is pure and stable.
Product separation and purification is essential to obtain pure C.I. acid blue 140. Appropriate separation methods, such as crystallization, extraction, chromatography, etc., are used to remove impurities. After purification, measure the purity, color, strength and other indicators of the product carefully. If it does not meet the standard, re-separate and purify.
The whole production process, safety and environmental protection are kept in mind. The raw materials and reaction products used may be toxic, corrosive, flammable, etc., and the operation is in accordance with safety procedures. Protective equipment is provided, and waste is properly disposed of to ensure personnel safety and environmental cleanliness.

How to store Cn + C.I. +Acid+Blue+140Disodium+4%2C4%27-%5BMethylenebis%284%2C1-Phenyleneimino%29%5DBis%5B1-Amino-9%2C10-Dihydro-9%2C10-Dioxoanthracene-2-Sulphonate%5D

This is the acid blue 140 disodium salt, and its storage method is quite exquisite. When placed in a cool, dry and well-ventilated place, away from heat sources and open flames, to prevent it from deteriorating due to heat. It is necessary to avoid direct sunlight, because light is easy to cause photochemical reactions and affect quality. At the same time, it should be stored separately from oxidants, acids, bases, etc., and must not be mixed in storage to prevent interaction from causing danger or reducing its quality. The storage container must be tightly sealed to prevent it from moisture and moisture absorption, causing its performance to change. If the storage environment is humid, this substance is easy to absorb moisture, or agglomerate, or affect its chemical stability. In addition, obvious warning signs should be set so that relevant personnel know its characteristics and storage requirements, and operate with caution. In this way, the acid blue 140 disodium salt can be properly stored to maintain its good quality and performance for subsequent use.
