8-Amino-1, 5-Naphtalenedisulfonic Acid Monosodium Salt

The preparation method of 8-amino-1,5-naphthalene disulfonic acid monosodium salt has been known in ancient times, and it is now detailed.
First, the sulfonation method. First take the naphthalene as the group, and sulfuric acid or fuming sulfuric acid is used for sulfonation. In this process, the concentration of sulfuric acid, temperature and reaction time are all key. Moderate high temperature can promote the sulfonation reaction to proceed quickly, but if it is too high, it is easy to cause side reactions to occur. Precise temperature control in a specific range allows sulfuric acid to interact ingeniously with naphthalene, so that the sulfonic acid group gradually enters the 1,5 position of the naphthalene ring to obtain 1,5-naphthalene disulfonic acid. After the neutralization method, with sodium hydroxide and other alkali substances moderately neutralized, adjusted to a suitable pH, to obtain 8-amino-1,5-naphthalene disulfonic acid monosodium salt body.
Second, the amination method. After obtaining 1,5-naphthalene disulfonic acid, the amination process is carried out. With a suitable amination reagent, such as ammonia or amine compounds, with the assistance of a catalyst, it can react with 1,5-naphthalene disulfonic acid. The choice of catalyst is of paramount importance, which can increase the reaction rate and reduce the required conditions for the reaction. After this amination, a part of the sulfonic acid group is cleverly combined with the amino group to form 8-amino-1,5-naphthalene disulfonic acid. After subsequent neutralization, crystallization and other fine operations, a pure 8-amino-1,5-naphthalene disulfonic acid monosodium salt can be obtained.
Third, improve the synthesis method. With the advance of science and technology, there are improved methods guided by the concept of green chemistry. High-efficiency and environmentally friendly catalysts are selected to optimize the reaction process, reduce energy consumption and pollution. Or innovation in the reaction medium, new media such as ionic liquids are used instead of traditional solvents to make the reaction milder, and the purity and yield of the product are also improved. These new methods are both timely and promising, opening up a new way for the preparation of 8-amino-1,5-naphthalene disulfonic acid monosodium salt.
