What is the preparation method of Sodium 2,7-Naphthalene Disulfonate?

The method of preparing sodium 2,7-naphthalene disulfonate is to start with naphthalene. First, the naphthalene is heated with sulfuric acid and the sulfonation reaction is carried out. This reaction needs to be carried out at a specific temperature and duration before the main product containing 2,7-naphthalene disulfonic acid can be obtained.
When operating, it is advisable to take an appropriate amount of naphthalene and place it in the reactor, and slowly add sulfuric acid. The concentration and dosage of sulfuric acid need to be precisely controlled. The heating process should also be carefully controlled. The initial temperature should not be too high, and then gradually rise to a suitable temperature range for the reaction, usually around 160-180 ° C, for several hours, so that the sulfonation reaction is sufficient.
After the reaction is completed, the product is cooled and neutralized with an appropriate amount The commonly used base is sodium hydroxide solution, which is neutralized until the solution is neutral or weakly alkaline. This process can obtain 2,7-naphthalene disulfonate sodium salt.
Subsequent, the neutralized solution is evaporated and concentrated to gradually remove the water and increase the concentration of 2,7-naphthalene disulfonate sodium. After cooling the crystals to a certain extent, the precipitated crystals are 2,7-naphthalene disulfonate sodium.
After being filtered again to remove the mother liquor, the crystals are washed with an appropriate amount of cold water to remove impurities. Finally, the crystals are placed in an oven and dried at a suitable temperature to obtain a pure 2,7-naphthalene disulfonate sodium product. Throughout the preparation process, attention should be paid to the control of conditions at each step, so as to obtain high-quality products.

What is the price range of Sodium 2,7-Naphthalene Disulfonate in the market?
