In the world of ink manufacturing, it also has its place. If the ink wants to achieve the effect of bright color and smooth printing, this compound can add a lot of color. In the ink, it can optimize the rheology of the ink, so that when printing, the ink is evenly coated, and the printed object is clear and full of color.
Furthermore, it is also indispensable in the industry of paper dyeing. Paper dyeing requires uniform color, bright and certain light resistance and water resistance. This material can give paper good dyeing properties. The dyed paper can maintain stable color and luster during daily use and storage, and is not easy to change color due to light and water vapor.
also shows its value in the process of leather dyeing. Leather dyeing requires dyes to penetrate deep into the interior of the leather and adhere firmly to ensure that the leather has a beautiful color and durability. This compound can penetrate leather fibers to achieve uniform dyeing, and the treated leather has a good feel and appearance.

Tetrasodium 2 - [[4 - [4 - [ (6 - Anilino - 1 - Hydroxy - 3 - Sulfonato - 2 - Naphthyl) Azo] - 1 - Naphthyl] Azo] - 6 - Sulfonato - 1 - Naphthyl] Azo] Benzene - 1,4 - Disulfonate, is the chemical name of a dye. The preparation process is as follows:
First, various raw materials need to be prepared, such as naphthalene compounds containing specific structures, anilines and sulfonation reagents.
The step of sulfonation is quite critical. With a specific naphthalene-based compound as the base, a suitable sulfonating agent, such as concentrated sulfuric acid or fuming sulfuric acid, is used to react at a certain temperature and time to introduce the sulfonic acid group at a specific position to generate a naphthalene derivative with a specific structure such as 3-sulfonation. This step requires careful control of the reaction conditions. Due to factors such as temperature and reagent ratio, the location and degree of the introduction of the sulfonic acid group are greatly affected. The
diazotization reaction is followed by the reaction of the sulfonated compound with sodium nitrite and inorganic acid (such as hydrochloric acid) at low temperature to convert the amino group into a diazonium salt. This reaction requires strict temperature requirements and generally needs to be maintained at 0-5 ° C to prevent the decomposition of diazonium salts In the coupling reaction of
, the obtained diazo salt is mixed with another naphthalene or benzene compound under appropriate pH value and temperature conditions. For example, the diazo salt and the compound containing naphthalene ring structure are coupled in a weakly alkaline environment and a specific temperature range (such as 10-30 ° C) to form a product containing azo structure. During this process, pH value and temperature have a significant impact on the reaction check point and product purity.
Repeat the above diazotization and coupling steps to construct a complex polyazo structure. After multi-step reaction, the product or impurities need to be separated and purified. Common methods include crystallization, filtration, washing, etc., to obtain high purity Tetrasodium 2 - [[4 - [4 - [ (6 - Anilino - 1 - Hydroxy - 3 - Sulfonato - 2 - Naphthyl) Azo] - 1 - Naphthyl] Azo] - 6 - Sulfonato - 1 - Naphthyl] Azo] Benzene - 1,4 - Disulfonate products. Each step of the reaction requires precise operation and strict monitoring to ensure product quality and yield.
