What is the production method of Disodium 3, 6-Dihydroxynaphthalene-2, 7-Disulphonate?
The method of making disodium 3,6-dihydroxynaphthalene-2,7-disulfonate is made after many exquisite chemical techniques.
Initially, naphthalene is used as the base material, which is commonly used in chemical industry. First, the sulfonation of naphthalene is performed. Concentrated sulfuric acid or fuming sulfuric acid is used as the sulfonating agent. At a specific temperature and time, the naphthalene reacts ingeniously with the sulfonating agent, and the sulfonic acid group is introduced at a specific check point of the naphthalene ring to obtain naphthalene sulfonate intermediates. In this step, the temperature, the concentration of the sulfonating agent and the reaction time need to be precisely controlled. If there is a slight difference, the product is impure or the yield is low.
Then, the naphthalene sulfonic acid intermediates are hydrox The alkali metal hydroxide, such as sodium hydroxide, is often co-placed in a specific reaction environment with the intermediate product, and accompanied by a suitable catalyst to partially convert the sulfonic acid group into a hydroxyl group. In this process, the reaction conditions need to be adjusted so that the hydroxyl group falls precisely at the 3,6 check point, resulting in the intermediate product of 3,6-dihydroxynaphthalene-2,7-disulfonic acid.
Then, with basic substances such as sodium carbonate or sodium hydroxide, it reacts with 3,6-dihydroxynaphthalene-2,7-disulfonic acid to neutralize its acidic group with the base and form a sodium salt, resulting in disodium 3,6-dihydroxynaphthalene-2,7-disulfonate. After the reaction is completed, it is separated and purified, such as crystallization, filtration, washing and other processes, to remove impurities and obtain pure products.
All reactions need to be carried out in a suitable reaction equipment, and accompanied by accurate temperature, pressure, and material ratio monitoring to ensure product quality and yield. Every step is related to the delicacy of chemical technology, one link is one link, and there is no slack.
