What are the physical and chemical properties of isoquinoline-8-trifluoromethanesulfonate?
Arsenic trisulfide (realgar) is a sulfide mineral of the realgar family, mainly containing arsenic disulfide (As ³ S ³). Its physical and chemical properties are as follows:
Physical properties
1. ** Morphology **: The crystal structure belongs to the monoclinic system. The crystal is fine, columnar, short columnar or needle-like, but less common. Usually dense and massive, often symbiotic with orpiment. The difference between the two is that the crystal of realgar is columnar, while the orpiment is flake.
2. ** Color **: Orange-red, the surface is often covered with orange-yellow powder. Its color is bright and unique, and it is more eye-catching in minerals.
3. ** Luster **: The crystal mask has a diamond luster, and the fracture is resin luster. Viewed from different angles, its unique luster effect can be seen, especially obvious under light.
4. ** Transparency **: slightly transparent. Although not completely transparent, it has a certain light transmission, which is different from some completely opaque minerals.
5. ** Hardness **: hardness 1.5 - 2. The hardness is low. It can be scratched with fingernails, which indicates that its texture is relatively soft.
6. ** Specific gravity **: Relative density 3.56. Compared with common stones, the specific gravity is large, and it will feel heavy in the hand.
7. ** Cleavage **: It has complete cleavage and is easy to crack into a smooth plane in a certain direction. This property makes it have a specific performance during processing or research.
Chemical properties
1. ** Stability **: It is relatively stable at room temperature and pressure, but at high temperature (heated to about 100 ° C), it will slowly oxidize and the color will gradually become darker.
2. ** Acid and alkaline **: It is insoluble in water and hydrochloric acid, soluble in nitric acid, and produces arsenic acid. The reaction equation is: As (2) S (2) + 10HNO (2) = 2H (2) AsO + 2H (2) SO + 10NO (2) ↑ + 2H (2) O. This property can be used to identify realgar, using its reaction characteristics with specific acids to determine the mineral composition.
3. ** Oxidation and Reductivity **: The arsenic in realgar is + 2 valent, which has a certain reducing property and can be oxidized to a high valence state under certain conditions. If left in the air for a long time, it will gradually be oxidized, and white or light yellow arsenic oxide will be formed on the surface. At the same time, in a specific chemical reaction system, realgar can also show oxidation and react with some substances with strong reducing properties.
What are the precautions in the preparation of isoquinoline-8-trifluoromethanesulfonate?
Many matters need to be paid attention to in the preparation of isoamyl triacetylsalicylate-8-naphthol utensils.
The quality of the first raw material, choose the best one. Acetylsalicylic acid needs to be pure, if impurities are present, or the reaction is skewed, the product is impure. 8-naphthol should also be carefully selected, and its purity is related to the fineness and yield of the product.
The second time is the reaction condition. Temperature control is essential, and this reaction is temperature-sensitive. High temperature may cause side reactions to be raw and the product will decompose; low, the reaction is slow, time-consuming and inefficient. It is appropriate to accurately control the temperature within a specific range to achieve the best reaction rate and yield.
Furthermore, the reaction apparatus should be clean and dry. The presence of water, or triggering side reactions such as hydrolysis, affects the product. Before the reaction, the container is cleaned with a washing liquid, dried or roasted to ensure an anhydrous environment.
Stirring is also critical. Stir well, the raw materials are fully contacted, and the reaction is accelerated to make the system temperature uniform, preventing local overheating or uneven reaction.
At the same time, pay attention to the reaction time. If the reaction is too short, the reaction is not completed, and the product is less; if it is too long, it may cause the product to deteriorate. According to the reaction process, stop it in time.
Post-treatment should not be ignored. The steps of product separation and purification should be careful. The selection method removes impurities to obtain pure products. Such as extraction, recrystallization, etc., the operation is standardized to ensure the quality of the product. < b Raw materials and products may be toxic or corrosive. During operation, protective equipment should be worn neatly and handled in a well-ventilated place. Waste should be handled in accordance with regulations to prevent pollution and hazards.
What is the market price of isoquinoline-8-ester trifluoromethanesulfonate?
Today there is a city of Sanxiang methylnaphthalene isotretinoin-8-chaff. What is the price? The price of the market often varies according to the quality of the goods, the abundance of the time, and the distance of the land.
If the quality is good and the new production is abundant, the price may be slightly lower; if the quality is inferior and the long-term storage, the scarcity of the production, the price will be high. Those who are close to the place and have access to the road, the price may be more affordable; those who are remote and have dangerous roads, the price may increase.
If you want to know the price, you must visit the merchants in the cities. I have heard that the things in the city have their own prices, or those who have good people change from time to time, in order to seek great profits. In the market today, the price of Sanxiang methylnaphthalene isotretinoin-8-bran is about tens to hundreds of dollars in normal times. However, this is not a fixed number, and it is difficult to predict when times change, whether it will increase or decrease.
And those who are in the market, where the trading place is full of people, and the price will also change accordingly. There are contenders, the price will be raised; those who are unsalable, the price will be depressed. To know the exact price of Sanxiang methylnaphthalene isotretinoin-8-bran, you should enter the market in person, consult all vendors, observe its supply and demand, and observe its market. Do not make assumptions, and must be based on actual observations, so as not to misjudge its price.
What are the storage conditions for isoquinoline-8-trifluoromethanesulfonate?
The storage conditions of Sanxiang A isopentene-8-ol are crucial for the preservation of this medicine.
According to the theory of "Tiangong Kaiwu" and the storage methods of various physical properties, it can be inferred that the storage of drugs needs to be observed in the right time and place to avoid its harm and preserve its properties. This Sanxiang A isopentene-8-ol should be placed in a cool place. Cover the warm air, it is easy to make the ingredients of the medicine volatilize, deteriorate, and damage its medicinal power. A cool place with a constant temperature can protect the inherent properties of the medicine, so that its efficacy can last for a long time without falling.
And it needs to be placed in a dry place. Moisture is the enemy of drugs, and in contact with water, it is prone to mildew and decay. In a dry environment, there is no water vapor intrusion, and the form and composition of the drug can be maintained stable, and it will not melt due to moisture or die due to mildew.
Furthermore, protection from light is also the key. Light has energy and can cause many chemical reactions. If Sanxiang A isoprene-8-ol is exposed to light, its molecular structure may be affected, causing the drug to change. Therefore, it should be hidden in a dark place or stored in a light-shielding device to protect the drug from light damage.
In addition, it should be sealed and stored. Sealing can block the intrusion of external air and impurities. The air contains oxygen and other components, or reacts with the drug such as oxidation; impurities are mixed in, which may also change the purity and properties of the drug. Sealed, the drug is isolated from the outside world, and its original quality can be preserved for a long time. In this way, the long-term effect and the full potency of the drug can be obtained by storing the isoprene-8-ol in a cool, dry, dark and sealed condition.
