Looking at its appearance, it often takes the form of white to light yellow crystalline powder, which is easy to store and transport, and is also easy to disperse in various reaction systems, which is conducive to giving full play to its chemical properties. Its solubility is quite special, and it can be soluble in water. This property is of great significance in many aqueous solution chemical reactions. After dissolving in water, it can be uniformly dispersed in an ionic state, which can be used as a good reaction medium or reactant to participate in many ion exchange, condensation and other reactions.
When it comes to melting point, the compound has a high melting point, which reflects its strong intermolecular forces and relatively stable structure. The higher melting point makes it able to maintain a solid state at general ambient temperatures, ensuring stability during storage and operation.
In addition, the monosodium salt of 2-amino-1,4-benzene disulfonic acid has a certain degree of hygroscopicity. In a humid environment, it is easy to absorb moisture in the air. This characteristic needs to be paid attention to when storing. The storage environment should be kept dry to prevent its physical morphology from changing due to moisture absorption, and even affect its chemical properties and performance.
It can be seen from the above that the physical properties of 2-amino-1,4-benzene disulfonic acid monosodium salts, such as appearance, solubility, melting point and hygroscopicity, play a key role in their application in chemical production, scientific research experiments, etc. Only by understanding and mastering these properties can this compound be better used.
What is the production method of 2-Amino-1, 4-Benzenedisulphonic Acid Monosodium Salt?
The preparation method of monosodium salt of 2-amino-1,4-benzene disulfonic acid, although the ancient book "Tiangong Kaiwu" does not directly describe this specific substance, its chemical creation method can be used for reference.
To make this substance, benzene can be used as the starting material first. In an appropriate reactor, add an appropriate amount of benzene, and use concentrated sulfuric acid as the sulfonation reagent. Control of reaction temperature and time is the key. If the temperature is high, the side reaction will occur; if the temperature is low, the reaction will be slow. At a moderate temperature, benzene and concentrated sulfuric acid will sulfonate to obtain 1,4-benzene disulfonic acid. This step needs to be carefully controlled so that the sulfonic acid group is accurately introduced into the 1,4 positions of the benzene ring.
Then, an appropriate amount of ammonia water is slowly added to the 1,4-benzene disulfonic acid to adjust the pH of the reaction system and promote the amino group to replace the hydrogen atom on the benzene ring to form 2-amino-1,4-benzene disulfonic acid. In this process, the reaction process needs to be closely monitored, which can be observed by analytical means such as chromatography.
Finally, 2-amino-1,4-benzene disulfonic acid is reacted with an appropriate amount of sodium hydroxide solution, and the monosodium salt of 2-amino-1,4-benzene disulfonic acid is obtained by neutralization. After that, the pure product can be obtained through crystallization, filtration, drying and other processes. Every step requires rigorous operation, from the amount of raw materials, reaction conditions, to the details of post-processing, all of which affect the quality and yield of the product.
2-Amino-1, 4-Benzenedisulphonic Acid Monosodium Salt What are the precautions in storage and transportation
2-Amino-1,4-benzene disulfonic acid monosodium salt is an important chemical substance. During storage and transportation, many matters need to be paid attention to to to ensure its quality and safety.
First, when storing, it must choose a dry, cool and well-ventilated place. Because of its hygroscopicity, if the cover is placed in a humid environment, it is easy to absorb moisture and agglomerate, resulting in quality damage. And the temperature is too high, or it may cause a chemical reaction that affects its stability. Therefore, the warehouse temperature should be controlled within an appropriate range and should not be exposed to direct sunlight.
Second, this substance should be stored separately from oxidants, acids, bases, etc., and must not be mixed.
Third, the storage area should be equipped with suitable containment materials to prevent leakage accidents. If leakage occurs unfortunately, it can be collected in time to avoid pollution to the environment.
Fourth, during transportation, it is necessary to ensure that the container is well sealed to prevent leakage, collapse, fall or damage. When loading and unloading, the operator should load and unload lightly, and do not operate brutally to avoid damage to the packaging.
Fifth, the transportation vehicle should also meet the relevant safety standards and be equipped with necessary fire equipment and leakage emergency treatment equipment. And during transportation, it should follow the prescribed route and do not stop in densely populated areas or traffic arteries.
In short, the storage and transportation of 2-amino-1,4-benzene disulfonic acid monosodium salt is of great significance, and it is necessary to strictly follow relevant regulations and operating procedures to ensure safety.
What is the price range of 2-Amino-1,4-Benzenedisulphonic Acid Monosodium Salt in the market?
The price of 2-amino-1,4-benzene disulfonic acid monosodium salt in the market is difficult to determine. The range of its price often varies for various reasons.
In the past market conditions, if the goods were of high quality and wide quantity, the price might be slightly lower; while the refined products and special suppliers, the price must be high. And the producers are different, and their work methods and costs are different, and the price is also different. The state of supply and demand in the market is also the cause of the change in price. If there are many people who want it, the supply is small, and the price will rise; conversely, if the supply exceeds the demand, the price may drop.
As far as the chemical market is concerned, the price of this product may fluctuate between thousands and tens of thousands of yuan per ton. However, today is different from the past. The price of raw materials, energy consumption fees, and administrative regulations have all changed in recent years, so the price also fluctuates. To determine the price, you need to consult chemical traders and producers, or carefully observe real-time market conditions to know its current value.
