What are the preparation methods of 4,4 '- [ (3,5-dimethylphenyl) imino] bis-1-butane sulfonate disodium salt?
To prepare the disodium salt of 4,4 '- [ (3,5-dimethylphenyl) oxy] bis-1-naphthalenesulfonic acid, the method is as follows:
First prepare 3,5-dimethylphenol and 1,4-naphthoquinone-2-sulfonic acid. Place an appropriate amount of 3,5-dimethylphenol in the reaction kettle, slowly add the alkali solution to form a phenolic salt solution. In this solution, at a suitable temperature and under stirring, gradually add 1,4-naphthoquinone-2-sulfonic acid. During the reaction, the temperature and reaction process should be closely monitored, and the reaction should not be too dramatic or too slow.
After the two are fully reacted, 4,4 '- [ (3,5-dimethylphenyl) oxy] bis-1-naphthalenesulfonic acid is formed. At this time, the reaction solution is cooled, and the sodium salt solution is added by a slow dropwise method to convert the sulfonic acid into the corresponding sodium salt. After the dropwise addition is completed, continue to stir for a period of time to ensure the complete reaction.
After the reaction is completed, the product is separated and purified. First, the insoluble impurities are removed by filtration, and then the filtrate is extracted several times with an organic solvent to remove the organic impurities. After that, the organic phase is concentrated and crystallized to obtain the crude product of 4,4' - [ (3,5-dimethylphenyl) oxy] bis-1-naphthalenesulfonic acid disodium salt.
In order to obtain a high-purity product, recrystallize the crude product. Select a suitable solvent, dissolve the crude product in it, heat and stir to dissolve, filter while hot, and cool the filtrate to crystallize. Then filter, wash the crystals with cold solvent, dry, and obtain a pure 4,4 '- [ (3,5-dimethylphenyl) oxy] bis-1-naphthalene sulfonate disodium salt. The whole preparation process requires following the operating specifications and controlling the reaction conditions to obtain the ideal product.

What is the market price of 4,4 '- [ (3,5-dimethylphenyl) imino] bis-1-butane sulfonate disodium salt?
I have not heard of "4%2C4%27-%5B%283%2C5-%E4%BA%8C%E7%94%B2%E5%9F%BA%E8%8B%AF%E5%9F%BA%29%E4%BA%9A%E6%B0%A8%E5%9F%BA%5D%E5%8F%8C-1-%E4%B8%81%E7%83%B7%E7%A3%BA%E9%85%B8%E4%BA%8C%E9%92%A0%E7%9B%90%E7%9A%84%E5%B8%82%E5%9C%BA%E4%BB%B7%E6%A0%BC%E4%B9%8B details". This name is either a new chemical medicine or a rare material. The change in its price is related to many things.
In the supply and demand of the city, if there are many people who need it, and there are few people who produce it, the price will be increased; if the supply exceeds the demand, the price will be suppressed. It also concerns the difficulty of its production. If the production requires rare materials and complicated methods, the price will be high; if the production is easy and the materials are wide, the price will be flat. And it is related to the competition of the city, the competition between the same industry, or the price will be reduced to attract customers; if there is no competitor, the price may be set independently.
However, I have no detailed information, it is difficult to judge the price of the city. To know the exact price, when visiting various pharmaceutical merchants, chemical companies, or inquiring the prices of various cities, the recent transaction price can be obtained.
