Disodium 5-Acetamido-3- (4-Dodecylphenyl) Azo-4-Hydroxy-Naphthalene-2, 7-Disulfonate
The author of "Tiangong Kaiwu", a strange book of ancient times, contains all kinds of techniques for creating things. Today's words "Disodium + 5 - Acetamido - 3 - (4 - Dodecylphenyl) Azo - 4 - Hydroxy - Naphthalene - 2,7 - Disulfonate", this is the name of a chemical substance. Its composition is complex, according to the name, it contains sodium elements, including "Disodium", which means disodium.
"5 - Acetamido" means it contains acetamide groups, which are in the 5th position of molecular structure. " 3 - (4 - Dodecylphenyl) "is shown to have a 4-dodecylphenyl group at the 3rd position, which is a long-chain alkyl group and is lipophilic." Azo "epiazo group, which is commonly found in many dyes and gives the substance color characteristics." 4 - Hydroxy "refers to a hydroxyl group at the 4th position, which has a certain polarity." Naphthalene - 2,7 - Disulfonate "has a naphthalene ring structure and has a sulfonic acid group at the 2nd and 7th positions, which makes the substance hydrophilic.
In summary, this substance is composed of sodium, acetamido, dodecyl phenyl, azo, hydroxyl, naphthalene ring and sulfonic acid group, etc. Each part is connected in a specific way to form a unique chemical structure, both lipophilic and hydrophilic, or has applications in specific fields such as dyes and surfactants.
What is the production process of Disodium 5-Acetamido-3- (4-Dodecylphenyl) Azo-4-Hydroxy-Naphthalene-2, 7-Disulfonate?
This is the process of preparing disodium 5-acetamido-3- (4-dodecylphenyl) azo-4-hydroxy-naphthalene-2,7-disulfonate. The method is as follows:
Take 4-dodecylaniline first, and react with sodium nitrite in an acidic medium by diazotization to form a diazonium salt. This step requires precise temperature control and acidity to prevent side reactions from occurring. If the cap temperature is too high or the acidity is improper, the diazonium salt is easy to decompose or cause other by-products to be produced, which will damage the reaction process.
Following the coupling of diazonium salt with 5-acetamido-4-hydroxy-naphthalene-2,7-disulfonate sodium. This step requires attention to the pH value and temperature of the reaction system. Appropriate pH value and temperature can promote the coupling reaction smoothly and increase the yield of the product. If the pH is too high or too low and the temperature is not suitable, the coupling reaction may be difficult to occur, or the product may be impure.
After the reaction is completed, a mixed system containing the target product is obtained. After separation and purification, crystallization, filtration, washing, etc. are often used to remove impurities and improve the purity of the product. When crystallizing, choose the appropriate solvent and crystallization conditions, so that the product preferentially forms crystal precipitation from the solution. Filtration can be divided into crystals and mother liquor, and washing removes impurities attached to the surface of the crystal to obtain high-purity disodium 5-acetamido-3- (4-dodecylphenyl) azo-4-hydroxy-naphthalene-2,7-disulfonate.
Throughout the preparation process, each step needs to carefully control the reaction conditions and fine operation to obtain products with good quality and high yield.
Disodium 5-Acetamido-3- (4-Dodecylphenyl) Azo-4-Hydroxy-Naphthalene-2, 7-Disulfonate What are the precautions in use
Disodium 5-acetamido-3- (4-dodecylphenyl) azo-4-hydroxy-naphthalene-2,7-disulfonate This substance, when using, there are many precautions that must not be ignored.
The first to bear the brunt is the safety issue. This compound may be potentially harmful, and it must be fully protected when exposed. Before starting the operation, you should read its safety data manual to understand the possible risks. If there is a risk of irritation to the skin and eyes, it is necessary to strictly wear protective equipment, such as gloves, goggles, etc. during operation to avoid skin and eyes invasion.
Furthermore, storage is also exquisite. It should be placed in a dry, cool and well-ventilated place, away from fire and heat sources. Due to its chemical properties or instability, improper storage or qualitative change will damage its effectiveness and even cause danger.
During use, follow the established procedures accurately. This compound is often used in specific industrial processes or experiments. The operation steps are carefully set and must not be changed. If there is any deviation, not only the experimental results may be affected, but also accidents may occur.
Repeat, waste disposal should not be ignored. After use, the residue or waste must not be discarded at will. It must be properly disposed of in accordance with relevant laws and guidelines. Because of its composition or containing substances harmful to the environment, arbitrary discharge will pollute the soil, water sources and harm the ecology.
In addition, ventilation conditions in the use place are also critical. To ensure smooth air circulation, it can avoid the accumulation of harmful gases and reduce the threat to the user's health.
All of these are the things that need to be paid attention to when using disodium 5-acetamido-3- (4-dodecylphenyl) azo-4-hydroxy-naphthalene-2,7-disulfonate, which should not be ignored to ensure safety and promote effect.
What is the market price range for Disodium 5-Acetamido-3- (4-Dodecylphenyl) Azo-4-Hydroxy-Naphthalene-2, 7-Disulfonate?
I don't know the price range of the city you said "Disodium + 5 - Acetamido - 3 -% 284 - Dodecylphenyl% 29Azo - 4 - Hydroxy - Naphthalene - 2% 2C7 - Disulfonate". This name is very complex, and it seems to be called a chemical. However, the price of the market often changes due to many reasons, such as the quality of the quality, the amount of production, the rise and fall of the demand, the distance of the land, and the passage of time.
If you want to know the exact price, you can get a near-real price when you visit a business in the market, ask a shop of chemical materials, or check a trading platform of chemical products, and look at its recent transaction price. Or looking for experts or insiders in the chemical industry, who have been involved in this industry for a long time, or know the approximate price.
Unfortunately, I have not personally involved in the chemical market, and there is no exact news of the price of this chemical, so it is difficult to know the price range. You can follow the path I mentioned and explore on your own, and you will definitely get the price you need.
