What are the preparation methods of 7,7 '-Ureylene-Bis- (4-Hydroxynaphthalene-2-Sulfonic Acid)?

The preparation method of 7,7 '-urea-bis (4-hydroxynaphthalene-2-sulfonic acid) has been known for a long time, and after years of precipitation, many parties have their own wonderful methods.
First, it can be started by specific naphthalene compounds. First take an appropriate amount of 4-hydroxynaphthalene-2-sulfonic acid, place it in a refined reactor, and control the dosage with precise measurement. Then, add an appropriate amount of urea, which is the key raw material for the reaction. The ratio of the two needs to be prepared according to a delicate formula to make the reaction smooth. Add an appropriate amount of catalyst, which has been selected by many parties to effectively promote the reaction process and improve the product generation rate. Under a suitable temperature and pressure environment, the reaction system operates slowly. The temperature needs to be constant in a certain range, such as between [X] ° C and [X] ° C, and the pressure needs to be maintained around [X] kPa. After several hours of reaction, the substances in the system are fully integrated and converted. When the reaction is approaching the end, the product can be purified by subtle separation techniques, such as filtration, crystallization, etc., to obtain 7,7 '-urea-bis (4-hydroxynaphthalene-2-sulfonic acid).
