What are the chemical properties of Trisodium 4-Hydroxy-4- (4-Anilino-5-Sulphonato-1-Naphthylazo) Naphthalene-2,7-Disulphonate
This is a chemical substance, the Chinese name or 4-hydroxy-4- (4-aniline-5-sodium sulfonate-1-naphthyl azo) naphthalene-2,7-disulfonate sodium. Its chemical properties are quite complex and vary according to its structure and composition.
Looking at its structure, it contains multiple sodium sulfonate groups, which endows it with good water solubility. Because the sulfonate group is hydrophilic, it is easy to dissociate into ions in water, so that the substance has good solubility in aqueous medium.
There are hydroxyl groups and azo groups. Hydroxyl groups can participate in the formation of hydrogen bonds, which has a significant impact on the physical and chemical properties of substances, such as enhancing intermolecular forces, affecting melting points, boiling points, etc. Azo-N = N- is a chromophore, which often gives compounds color, or can be used in the field of dyes.
Aromatic structures such as aniline and naphthalene groups in this substance add stability and conjugation. The conjugate system can enhance the ability of molecules to absorb and emit light, or has optical activity.
However, its chemical properties are also restricted by electronic effects and spatial effects of surrounding groups. Adjacent groups may affect their reactivity and physical properties. In summary, this substance exhibits chemical properties such as water solubility, color characteristics, and optical activity due to its unique structure, and may have important uses in dyes, optical materials, and other fields.
What is the production method of Trisodium 4-Hydroxy-4- (4-Anilino-5-Sulphonato-1-Naphthylazo) Naphthalene-2,7-Disulphonate?
The method of preparing trisodium 4-hydroxy-4- (4-anilinyl-5-sodium sulfonate-1-naphthyl azo) naphthalene-2,7-disulfonate requires naphthalene as the starting material. Naphthalene is sulfonated and heated with sulfuric acid under specific conditions to obtain a mixture of naphthalene sulfonic acid. Finely separated to obtain 2,7-naphthalene disulfonic acid, which is the key intermediate.
Then, 2,7-naphthalene disulfonic acid reacts with sodium nitrite in an acidic medium. The temperature is controlled at a suitable range, so that it can be precisely diazotized to form diazonium salts. At the same time, using aniline as raw material, through specific sulfonation steps, 4-aniline-5-sulfonic acid was obtained. This product was coupled with the above diazonium salt under weakly basic conditions, and the reaction conditions, such as temperature, pH value, etc., were carefully adjusted to make the two couple smoothly, resulting in 4 - (4-aniline-5-sodium sulfonate-1-naphthyl azo) naphthalene-2,7-disulfonic acid.
Finally, the product is reacted with an appropriate amount of sodium hydroxide, neutralized with acid and base, and the reaction process is precisely regulated to obtain trisodium 4-hydroxy-4- (4-aniline-5-sulfonate-1-naphthyl azo) naphthalene-2,7-disulfonate. The whole process requires strict control of the reaction conditions, including temperature, pH, reaction time, etc., and each step of the intermediate needs to be finely separated and purified to ensure the purity and quality of the product. In this way, this compound can be prepared.
Trisodium 4-Hydroxy-4- (4-Anilino-5-Sulphonato-1-Naphthylazo) Naphthalene-2,7-Disulphonate is harmful to human health
"Tiangong Kaiwu" is written in a simple and practical style. Today, in its style, the answer is about "Trisodium 4 - Hydroxy - 4 - (4 - Anilino - 5 - Sulphonato - 1 - Naphthylazo) Naphthalene - 2,7 - Disulphonate is harmful to human health".
This substance is called "4 - Hydroxy - 4 - (4 - Anilino - 5 - Sodium Sulfonate - 1 - Naphthyl Azo) Naphthalene - 2,7 - Sodium Disulfonate", often seen in the field of chemical printing and dyeing. Its effect on human health needs to be investigated in detail.
As far as is known, if this substance is exposed to the skin, it may be irritating, causing redness and itching of the skin. If inhaled inadvertently, or affecting the respiratory tract, it will make people cough and asthma. If taken by mistake, it may hurt the stomach, cause vomiting and abdominal pain.
However, the severity of the harm of this substance also depends on the dose and duration of exposure. A small amount is touched for a short time, or only causes slight discomfort. After proper treatment, it can heal quickly. If exposed to a large amount for a long time, it may increase health risks and damage the functions of the liver and kidneys.
Therefore, when using this substance, strictly follow the procedures and prepare protective equipment, such as gloves, masks, goggles, etc., to prevent it from coming into contact with the body, skin, and respiratory tract. If in contact, rinse quickly with water, and seek medical attention in severe cases. In this way, the harm to human health can be reduced.
What is the price range of Trisodium 4-Hydroxy-4- (4-Anilino-5-Sulphonato-1-Naphthylazo) Naphthalene-2,7-Disulphonate in the market?
I do not know the price of the "Trisodium+4-Hydroxy-4-%284-Anilino-5-Sulphonato-1-Naphthylazo%29Naphthalene-2%2C7-Disulphonate" in the market. This is a fine chemical or special chemical product, and its price often varies according to quality, quantity, supply and demand, method of preparation and market conditions.
If you want to know the price of the ancient business, you must visit the cities. In the ancient city, the price of the goods is not the same, depending on the quality of the goods, the main plan, the price may vary. In today's world, although there are special things, it is still reasonable.
If you want to get the price of this product, you should consult the seller on the platform of chemical trade, such as a professional chemical raw material trading network, or visit the broker or dealer of chemical materials. Or attend a chemical exhibition and communicate with various industry players to know the approximate price. Or because of the thinness of the material and the difficulty of the technology, the price is different. Or there are those who have a high price, because of their pure quality, they are suitable for high-end areas; or those who are cheap, the quality is slightly inferior, and they can be used in ordinary ways. However, the exact number of prices cannot be obtained without asking the cities personally.
