The method of preparing disodium 2,2 '- [ (9,10-dioxo-9,10-dihydroanthracene-1,4-diyl) diamino] bis (5-methylbenzene sulfonate) is a delicate and specific step.
At the beginning, when anthraquinone is based, anthraquinone has a unique chemical structure and is crucial in the initial stage of the reaction. The anthraquinone is treated so that it meets the imino-containing reagent under specific conditions. This reaction requires fine control of the temperature and reaction environment, and the temperature may be maintained within a certain range, neither too high to overreact nor too low to slow down the reaction.
Then, the benzene sulfonic acid containing methyl is introduced. The addition of this substance needs to follow a certain order and ratio. Due to its different chemical activities, the proportion is slightly poor, or the product is impure. In this process, the use of catalysts is also indispensable. The catalyst can accelerate the reaction process, and promote the effective breaking and recombination of chemical bonds between the reactants.
When the reaction is carried out, the reaction process needs to be closely monitored. Or by specific analytical methods, such as chromatographic analysis, to observe the degree of reaction and product formation. When the reaction reaches the expected stage, the separation and purification steps need to be carried out. Solvent extraction can be used to select a suitable solvent to dissolve the target product, leaving impurities in other places. After crystallization and other means, the product is further purified to obtain pure disodium 2,2 '- [ (9,10-dioxo-9,10-dihydroanthracene-1,4-diyl) diamino] bis (5-methylbenzene sulfonate). The whole process requires fine operation and strict control by the experimenter to obtain high-quality products.

The 2,2 '- [ (9,10 - dioxo - 9,10 - dihydroanthracene - 1,4 - diyl) diamino] bis (5 - methylbenzene sulfonate) of disodium, when used, there are several ends to pay attention to.
First, the properties of this substance are clear. Its solubility and stability vary in different media. If it is in water, or due to changes in temperature and pH, it shows a different shape. If the temperature is high, or the solubility is increased, then the temperature drops, or there is a precipitation phenomenon. And in different environments of acid and base, its structure may also change, resulting in its effect being different from usual.
Second, use this material, and the amount is controlled to the fullest. If it is too little, it will not achieve the expected effect; if it is too much, it may cause waste, and it may cause other changes. For example, in the dyeing and weaving industry, if the amount is appropriate, the color will be uniform and firm. If the amount is inappropriate, the color will be uneven and easy to fade.
Furthermore, the shadow of the environment should not be ignored. When using this material, dust, moisture, light, etc. are all involved. If the light is exposed for a long time, it may cause it to decompose; if the humidity is too high, it may cause it to deliquescent and damage its quality.
In addition, the user should be familiar with it. This substance may be irritating to the body, touching the skin or entering the eyes, and can cause discomfort. When using it, use it in front of protective equipment, such as gloves and eyepieces, and in a well-ventilated place to prevent gas from entering the body.
In short, use 2,2 '- [ (9,10-dioxo-9,10-dihydroanthracene-1,4-diyl) diimino] bis (5-methylbenzene sulfonate) in disodium, in terms of behavior, quantity control, environment, and safety, all must be carefully observed to achieve the purpose of good use.
