Monoisopropylamine70% need to pay attention to when storing
Monoisopropylamine, containing 70% and 25%, when hiding, all kinds of matters must not be ignored. This is an organic compound, active, corrosive, and flammable and volatile. The way to hide is related to safety and should not be careless.
First, it should be placed in a cool and well ventilated place. Cover it flammable and volatile, if it is in a warm place, its gas is easy to gather, in case of open fire or hot topic, it may cause fire, even the risk of explosion. And well ventilated, it can quickly disperse the volatile gas, so as not to accumulate in a closed space.
Second, it must be kept away from fire and heat sources. The heat source of the kindling is the cause of its explosion. When the surrounding area is within ten feet, when there is no open fire, the electrical equipment must also be explosion-proof to prevent the generation of electric sparks and cause accidents.
Furthermore, the storage place should be isolated from oxidants, acids, etc. Monoisopropylamine is prone to violent reactions when it encounters oxidants; when it encounters acids, it will form salts and release heat, which can be dangerous. Therefore, different types of substances should be placed in their own places and must not be mixed.
In addition, the container must be well sealed. Because of its corrosive and volatile nature, if the container leaks, it will not only damage the substance, but also its escape gas, which can harm the surrounding environment and people. Sealed tightly, there is no such problem.
In addition, the storage area should be equipped with the corresponding variety and quantity of fire fighting equipment and leakage emergency treatment equipment. Once something happens, it can be dealt with quickly to reduce its harm. And the label is clear, indicating its dangerous characteristics, so that viewers are aware of the warning and dare not ignore it. In this way, it is safe to hide monoisopropylamine.
What are the physical properties of Monoisopropylamine70%?
The physical properties of monoisopropylamine (70% and 25%) are particularly important. This substance is a colorless to light yellow liquid with a strong ammonia smell and a pungent smell. Its boiling point is between 31 ° C and 33 ° C, and it is volatile at room temperature and pressure.
The density of monoisopropylamine is less than that of water, about 0.694g/cm ³. It is soluble in water and miscible with most organic solvents, such as alcohols and ethers. This is because the molecular structure contains amino and isopropyl groups. Its vapor pressure is quite high, and it is easy to form a flammable vapor cloud. In the air, it is easy to cause combustion and explosion when exposed to fire sources.
Furthermore, monoisopropylamine is hygroscopic, can absorb water vapor from the air, and is alkaline, and can neutralize with acids. Due to its alkaline characteristics, it can react violently with acidic substances to generate corresponding salts. In addition, the flash point of this substance is low, about -37 ° C. It is easy to burn in the event of open flames and hot topics, and will produce toxic nitrogen oxide fumes when burned. Its explosion limit is between 1.6% and 10.4% (volume fraction). When the concentration is in this range, there is a risk of explosion in case of fire source. When used and stored, extra caution should be taken.
Is Monoisopropylamine70% chemically stable?
Wen Jun inquired about the chemical stability of monoisopropylamine at 70% and 25% concentrations. Monoisopropylamine has strong alkalinity and high activity. Its stability is often influenced by many factors.
In terms of concentration, monoisopropylamine at 70% concentration becomes more complex due to the large proportion of solute. At higher concentrations, its chemical activity or molecular spacing is slightly enhanced, but under proper storage conditions, it can also maintain a certain stability. However, in case of high temperature, open flame or strong oxidant, it may cause a violent reaction and suddenly lose stability.
As for the concentration of 25%, due to dilution, the probability of intermolecular collision is reduced, and the chemical activity is relatively mild. Under normal circumstances, the stability is slightly better than that of 70%. However, its essence is still active alkaline substances. If the storage environment is not good, such as high humidity and coexistence with acidic substances, it will also cause chemical properties to change and stability to be damaged.
Overall, whether it is 70% or 25% concentration of monoisopropylamine, it is not absolutely stable. To ensure its chemical stability, strict storage specifications must be followed, and it must be placed in a cool, ventilated place away from fire sources and oxidants, so as to reduce the risk of deterioration and maintain its inherent chemical properties.
What is the production process of Monoisopropylamine70%?
The process of preparing 70% and 25% propylamine is as follows:
Start with propanol and ammonia raw materials, and the two are used in appropriate catalysis and specific components. The catalysts used are often solid acids, such as silicone, zeolite, etc., which can effectively promote the reaction. The reaction speed of the reaction parts is generally controlled at 200-400 degrees Celsius, and the reaction force is maintained at 1-5 MPa. In this environment, the biochemical reaction of propanol and ammonia to generate propane, dipropylamine and other by-products.
After the reaction is completed, the obtained mixture needs to be divided into two parts. First, the preliminary steaming is carried out, according to the difference between the boiling temperature of each product, and the low boiling material is divided into high boiling material. The boiling temperature of propylamine is 32-33 degrees Celsius, which can be used for this characteristic, and it can be collected in the appropriate temperature range. In order to obtain 70% of the propylamine, it is necessary to control the tray, current ratio, etc. by means of precision. If you want to obtain a 25% dilute solution, it is necessary to extract the high degree of propylamine, in proportion to the appropriate solution. It is commonly used to dissolve water and mix it evenly to obtain 25% of the propylamine.
