What is the preparation method of 7,7 '-Ureylenebis (4-Hydroxy-2-Naphthalenesulfonic Acid)
To make 7% 2C7% 27-urea double (4-hydroxy-2-naphthalenesulfonic acid), the method is as follows:
First take an appropriate amount of 4-hydroxy-2-naphthalenesulfonic acid and place it in a clean kettle. Heat slowly over a gentle fire to melt the material gradually. During this period, stir carefully to make it evenly heated.
When the material is in a suitable molten state, slowly add urea according to a certain ratio. When adding, do not speed up to avoid overreaction.
Add it, raise the heat, maintain a certain temperature in the kettle, so that the two can fully react. During this process, continue to stir to ensure that the reactants are fully integrated.
During the reaction, it is necessary to pay close attention to the changes in the kettle and observe the color, texture and other signs. After a period of time, when the reaction reaches the expected level, remove the kettle from the fire and let it cool gradually.
Wait to cool to an appropriate temperature, and dissolve the product from the kettle with a suitable solvent. Then, filter out the insoluble matter with a filter to obtain a clear liquid.
Pour this liquid into another container, adjust its pH with a specific reagent, and allow the product to slowly precipitate. The precipitated matter is filtered with filter paper, and then rinsed with an appropriate amount of clean solvent to remove impurities.
Finally, the filtered product is placed in a well-ventilated and temperature-appropriate place to dry to obtain 7% 2C7% 27-urea-bis (4-hydroxy-2-naphthalenesulfonic acid). Throughout the process, it is necessary to follow the procedures and pay attention to factors such as heat, ratio, and time to obtain a pure product.
What is the price range of 7,7 '-Ureylenebis (4-Hydroxy-2-Naphthalenesulfonic Acid) in the market?
Today, 7% 2C7 '-urea-bis (4-hydroxy-2-naphthalenesulfonic acid) is available in the market. What is its price? I should answer you in detail with the style of ancient times.
7% 2C7' -urea-bis (4-hydroxy-2-naphthalenesulfonic acid) This substance is widely used in the field of chemical industry. It can be used as a dye aid or in the process of synthesis. However, its market price often changes for many reasons.
First, the price of raw materials is the main reason. If the price of all the raw materials required for the preparation of this compound rises, the price of 7% 2C7 '-urea-bis (4-hydroxy-2-naphthalenesulfonic acid) will also rise. On the contrary, if the price of raw materials falls, its price may drop.
Second, the situation of supply and demand has a huge impact. If the market faces strong demand for this product and limited supply, the price must be high. If supply exceeds demand, merchants will sell or reduce prices to promote it.
Third, the technique of production is also related. Advanced methods can reduce costs, prices or be close to the people. If the technique is not enough, the cost will be high, and the price will be difficult to lower.
As for the price range, roughly speaking, it is between a few hundred and several thousand yuan per kilogram. If the quality is high, it is suitable for high-end areas, and the price may be close to several thousand yuan. If the ordinary quality is used for general industry, the price may be several hundred yuan per kilogram. However, this is only an approximation, and the actual price should be carefully studied according to the current market situation and the policies of the merchant.
