What is the production process of sodium disodium 2-Naphthol-3,6-Disulfonate?

The production process of disodium 2 - Naphthol - 3,6 - Disulfonate (Disodium 2 - Naphthol - 3,6 - Disulfonate) is the key to the production of disulfonate. The method is as follows:
First, use the naphthol group and put it into a specific reaction kettle. In the kettle, the first sulfation of sulfonic acid, such as sulfuric acid or sulfuric acid, is the key to sulfation. In case of naphthol, the sulfonic acid group is then connected to the 3,6 positions of naphthol. This reaction needs to be controlled. Usually, it starts at a low level and rises to an appropriate level,~ 120 - 180 ° C, so that the reaction is smooth and sufficient, and the middle-grade naphthol - 3,6 - disulfonic acid is obtained.
, take the middle of this, and reverse the liquid. Commonly used, such as oxidized solution, the two blend, naphthol-3,6-disulfonic acid, the oxygen radical of naphthol-3,6-disulfonic acid is synthesized into water, and the sulfonic acid group is combined to form naphthol-3,6-disulfonic acid. This step also needs to control the reaction. Especially heavy pH value, so that it is neutral or slightly good.
After the reaction is completed, the product is precipitated by a crystal method. The solution is cooled down, and the solution is cold, and the crystal of dinaphthol-3,6-disulfonic acid is precipitated due to its solubility. By the method of separation, the solid liquid is separated to obtain a solid crude product. More washed with water, in addition to water, and then dry, high quality products can be obtained. In this way, the sulfonic acid is oxidized, formed, crystallized, and oxidized, and the best two-naphthol-3,6-disulfonic acid is obtained.
