Isopropyl isobutyrate (Isopropyl Acetate), its physical properties are as follows:

Isopropyl isobutyrate is a colorless and transparent liquid at room temperature, and the view is clear and clear, just like the purity of a mountain spring. Smell it, it has a fruity smell, fresh and fragrant, just like being in a spring orchard, its fragrance is elegant and pleasant.

The boiling point of this substance is about 118-119 ° C. When the temperature gradually rises, it is like ice melting in water, turning from liquid to gas, and rising. Its melting point is around -80 ° C, just like the extreme cold of winter. At this low temperature, isopropyl isobutyrate condenses into a solid state, which is as stable as ice.

The density of isopropyl isobutyrate is lighter than that of water, about 0.87 (g/cm ³). If it is placed in one place with water, it can be seen that it floats on the water, like a light boat in the blue waves. Its solubility is also unique, and it can be miscible with organic solvents such as alcohols and ethers. It is like water emulsifying with each other, but it is difficult to dissolve in water, just like the difference between oil and water.

Furthermore, the flash point of isopropyl isobutyrate is about 18 ° C, which is the key characteristic of its explosion. In case of open flames and hot topics, it is like dry firewood in case of fire, which is very easy to burn. It can form an explosive mixture in the air, like a lurking dangerous fire. If you are not careful, it may cause a violent explosion and endanger the safety of your surroundings.

What are the chemical properties of isopropyl acetate?

Isopropyl isobutyrate (Isopropyl Acetate) is one of the organic compounds. Its chemical properties are quite unique, and I will describe them in detail.

First of all, its physical properties, isopropyl isobutyrate is often colorless and transparent liquid, with a fragrant smell, just like the fragrance of flowers and fruits, which is quite pleasant to smell. Its boiling point is about 112 to 113 degrees Celsius, and its density is lighter than that of water. It is insoluble in water, but it can be miscible with many organic solvents such as ethanol and ether.

When it comes to chemical properties, isopropyl isobutyrate has the general properties of ester compounds. First, it can be hydrolyzed. Under the catalysis of acid or base, it interacts with water and breaks ester bonds. In an acidic environment, the hydrolysis reaction is reversible to produce isobutyric acid and isopropanol; in an alkaline environment, the hydrolysis is more thorough to produce isobutyric acid salts and isopropanol. This hydrolysis property is widely used in organic synthesis and chemical production.

Second, isopropyl isobutyrate can undergo alcoholysis. Under specific conditions, the alkoxy group in the ester group can be replaced with other alcohols to form new esters and alcohols. This reaction provides an important way for the preparation of various ester compounds.

Third, due to the presence of alkyl groups in the molecular structure, substitution reactions can occur. Under appropriate conditions, the hydrogen atom on the alkyl group can be replaced by other groups such as halogen atoms and nitro groups, thereby deriving a variety of functional compounds.

Fourth, isopropyl isobutyrate can undergo oxidation reactions when exposed to strong oxidants, but the specific oxidation products will vary depending on the type of oxidant and reaction conditions.

In addition, under the conditions of heating or lighting, the chemical bonds within the molecule may be rearranged to form isomers with different structures. This phenomenon adds many variables and interest to the study of organic chemistry.

In conclusion, isopropyl isobutyrate has rich and diverse chemical properties, and is indispensable in the fields of organic synthesis, fragrance preparation, and paint solvents.

What are the precautions for using isopropyl acetate?

Isopropyl Acetate (Isopropyl Acetate), when using, all kinds of precautions must be paid attention to.

The first thing to bear the brunt is safety. This substance is flammable, so in the place of use, open flames and hot topics must be strictly avoided. Fireworks must not be done. Electrical equipment is also selected to be explosion-proof to prevent accidental explosion. When handling, be sure to handle it with care to avoid damage to its containers and material leakage. If it is unfortunate to leak, quickly cut off the fire source, evacuate personnel to a safe area, and strengthen ventilation. Small leaks can be absorbed by inert materials such as sand and vermiculite; large leaks need to be built embankments or dug for containment, and then properly disposed of.

Furthermore, it is related to health. Isopropyl isobutyrate is irritating to the eyes, respiratory tract and skin. When using, protective gear is indispensable. Goggles can protect the eyes from damage, gas masks can filter harmful gases, and protective clothing and gloves protect the skin. If you accidentally touch the skin, rinse with plenty of water as soon as possible; if you enter the eyes, you must also rinse with running water or normal saline, and seek medical attention in time. Long-term or repeated contact may cause damage to the nervous system, so after work, you should seek fresh air to soothe the body and mind.

Also, storage is also important. It should be placed in a cool and ventilated compartment, away from fire and heat sources. The warehouse temperature should not exceed 30 ° C, and should be stored separately from oxidants and acids, and should not be mixed. The storage area must be equipped with leakage emergency treatment equipment and suitable containment materials to ensure safety.

All these are the key points to pay attention to when using isopropyl isobutyrate. All details should not be ignored, so as to ensure the safety of operation and avoid accidents.

What is the market price range for isopropyl acetate?

Isopropyl acetate (Isopropyl Acetate) is an organic compound commonly used in the chemical industry and is widely used in coatings, inks, adhesives and many other industries. Its market price is influenced by a variety of factors, so it is difficult to determine the range.

The first to bear the brunt is the cost of raw materials. The preparation of isoacetone acetate is mostly made of acetic acid and isopropanol through esterification reaction. If the price of these two changes due to market supply and demand, crude oil price fluctuations, and production process changes, the cost of isoacetone acetate will also fluctuate, eventually causing its market price to fluctuate. If the price of crude oil soars, the price of acetic acid and isopropanol, which are derivatives, will rise, and the price of isoacetone acetate will also rise.

Furthermore, the relationship between supply and demand in the market is also key. If downstream industries such as coatings and inks are booming, the demand for isoacetone acetate will increase sharply, while the supply is relatively stable or the growth is slow, the price will rise easily; conversely, if the downstream industry is sluggish, the demand will drop sharply, and the production enterprises are overcapacity and oversupply, the price will go down.

The production process and technical level also have an impact. Advanced production processes can improve production efficiency, reduce energy consumption and costs. If enterprises can take the lead in adopting new technologies, the cost of their products will be reduced, and the market pricing will be more advantageous, or the overall market price will change.

Regional factors cannot be ignored. Different regions have different prices due to differences in transportation costs, market competition, and local policies. Where the economy is developed and the demand is concentrated, or the price is slightly lower due to intense competition; where it is remote and inconvenient to transport, the price may be slightly higher due to increased costs.

To sum up, the market price of isoacetone acetate is intertwined due to factors such as raw material costs, supply and demand, production processes, and regions. It is difficult to determine a fixed range. It is necessary to consider the specific time and space situation in detail to obtain a relatively accurate price cognition.
