What are the physical properties of Sodium 1-Naphthylamine-4-Sulfonate?

Sodium-1-naphthylamine-4-sulfonate, having a number of physical properties. It is white to light gray powder and soluble in water because it contains hydrophilic sulfonic acid groups, which can be well dispersed in aqueous media.
Looking at its melting point, it is about 300 ° C. The higher melting point reflects its strong intermolecular force and relatively stable structure. The substance has strong hygroscopicity and is prone to moisture absorption and deliquescence in humid air. The sulfonic acid groups are prone to form hydrogen bonds with water molecules.
Its density is about 1.5-1.7g/cm ³, which shows the degree of compactness of electron accumulation in the solid state. Under light, sodium-1-naphthylamine-4-sulfonate has good stability and is not easy to decompose rapidly due to light, but long-term strong light exposure may slightly affect its structure.
Its aqueous solution is neutral or slightly acidic, which is caused by partial ionization of the sulfonic acid group. And the substance has limited solubility in organic solvents, and is only slightly soluble or insoluble. Because its molecular polarity is quite different from that of most organic solvents, according to the principle of similar miscibility, its solubility is poor.

What is the chemistry of Sodium 1-Naphthylamine-4-Sulfonate?

Sodium 1 - Naphthylamine - 4 - Sulfonate is a kind of organic compound. It has the following chemical properties:
This substance is soluble in water because it contains sulfonic acid groups. Sulfonic acid groups have strong hydrophilicity and can form hydrogen bonds with water molecules, so they exhibit good solubility in water.
In an acidic environment, amino groups (-NH2O) are easily protonated and converted to the form of -NH. This change will cause changes in the charge distribution of molecules, which in turn affect their solubility and reactivity.
Its sulfonic acid groups are acidic and can react with bases to form corresponding salts. This property allows it to act as a neutralizing agent or participate in ion exchange reactions in some chemical reactions.
In terms of redox properties, the naphthalene ring structure of the compound can be oxidized under specific conditions. For example, under the action of strong oxidants, the naphthalene ring may open the ring or undergo other oxidation reactions to generate a variety of oxidation products.
In addition, because its molecules contain aromatic rings and functional groups such as amino groups and sulfonic acid groups, it can participate in many electrophilic substitution reactions. Like halogenation, nitrification, sulfonation and other reactions, the hydrogen atom on the aromatic ring can be replaced by other groups, and the reaction check point is mostly affected by the localization effect of amino groups and sulfonic acid groups. The amino group is an ortho-and para-site group, and the sulfonic acid group is a meta-site group, and the two work together to determine the main product of the substitution reaction.
Under specific catalyst and reaction conditions, its amino group may also participate in the condensation reaction, react with other compounds containing active groups such as carbonyl groups, form new C-N bonds, and construct more complex organic structures.

What is the production method of Sodium 1-Naphthylamine-4-Sulfonate?

Sodium 1 - Naphthylamine - 4 - Sulfonate (sodium 1 - naphthylamine - 4 - sulfonate) has the following numbers in the past.
First, use 1 - naphthylamine as the base to interact with sulfuric acid. In a suitable container, add an appropriate amount of 1 - naphthylamine, and gradually add sulfuric acid. At this time, pay attention to the control of temperature. If the temperature is too high, it may cause side reactions that affect the purity of the product. Stir slowly to make it fully react. The concentration and dosage of sulfuric acid, as well as the temperature and time of the reaction, are all key factors. After fine conditioning, 1-naphthylamine and sulfuric acid are combined according to specific proportions and conditions to form 1-naphthylamine-4-sulfonic acid, and then neutralized with alkali to obtain 1-naphthylamine-4-sulfonic acid sodium.
Furthermore, there are also those who use naphthalene as the starting material. Naphthalene is first sulfonated, with concentrated sulfuric acid or fuming sulfuric acid as the sulfonating agent, and naphthalene interacts with it to introduce a sulfonic acid group to obtain naphthalenesulfonic acid. However, there are many isomers of naphthalenesulfonic acid, and if you want to obtain a specific 1-naphthalenesulfonic acid, 1-Naphthalenesulfonic acid is enriched by various means, such as controlling temperature, reaction time, concentration and dosage of sulfonating agent, etc. Then, 1-Naphthalenesulfonic acid is aminolyzed, and ammonia is used as the aminolytic agent. Under suitable conditions such as temperature and pressure, the sulfonic acid group is replaced by amino group to obtain 1-naphthalamine-4-sulfonic acid. Finally, it is neutralized by base and converted into 1-naphthalamine-4-sulfonate sodium.
There are other ways, but they all revolve around the selection of raw materials and the combination of reaction steps. Each method has its own advantages and disadvantages. In actual preparation, it is necessary to weigh and choose the good one according to many factors such as the availability of raw materials, cost considerations, and product purity requirements.

What are the precautions for Sodium 1-Naphthylamine-4-Sulfonate during storage and transportation?

Sodium-1-naphthylamine-4-sulfonate, when hiding and shipping, there are several things to pay attention to.
First and foremost, the nature of this material, sodium-1-naphthylamine-4-sulfonate has deliquescence, so it must be stored in a dry place to prevent moisture and damage its quality. And must be protected from heat and open flames, because it is heated or exposed to open flames, or causes dangerous changes, such as the risk of explosion.
Second word packaging, when shipping, it should be packed in a suitable package. The packaging must be strict and solid to prevent it from leaking out. If it leaks out, it will not only stain other things, but also cause harm if people touch it. If it accidentally touches the skin, wash it with plenty of water as soon as possible; if it enters the eyes, it is more appropriate to seek medical help urgently.
And it is taboo to mix, sodium-1-naphthylamine-4-sulfonate should not be mixed with strong oxidants, strong alkalis, etc. If this number is encountered, it may cause severe reactions, and there is an unfathomable risk.
Furthermore, in the library, it is advisable to set up a clear logo to remember the name, nature, danger and emergency measures of this thing. The carrier should also know the details, and always check whether the packaging is complete on the way. If there is any abnormality, it will be disposed of immediately. In this way, the sodium-1-naphthylamine-4-sulfonate is safe for transportation.
