In the synthesis process of some fine chemical products, it can participate in the reaction as an intermediate and undergo a series of chemical transformations to generate compounds with specific functions.
In the fragrance industry, diisobutyl ketone can be used as a fragrance component or used to prepare fragrances, giving the product a unique aroma. And because of its low toxicity and moderate volatility, it can be used in some products that require safety and odor.
In summary, diisobutyl ketone plays an indispensable role in the fields of solvents, organic synthesis, and fragrances, and has made significant contributions to the development of related industries.
What are the physical properties of Diisobutyl Ketone?
Diisobutyl ketone is one of the organic compounds. It has various physical properties, which are described as follows:
Looking at its appearance, under room temperature and pressure, it is a colorless, transparent and aromatic liquid, and its clarity can be seen. Its smell is fragrant, but it is inhaled too much, or it is harmful to the body.
When it comes to boiling point, it is about 168.1 ° C. When the temperature reaches this point, diisobutyl ketone gradually changes from liquid to gaseous state. This boiling point is an important parameter for chemical separation, purification and other operations.
Its melting point is about -46.0 ° C. When the temperature drops to this temperature, the liquid condenses into a solid state. The value of the melting point should be carefully considered during storage and transportation to prevent its state from changing. In terms of density,
is about 0.805 (g/cm ³), which is lighter than water. In mixed systems, it often floats on water, and this property can be seen in chemical phase separation operations. The solubility of
diisobutyl ketone is also considerable. It is slightly soluble in water, but it can be miscible with organic solvents such as alcohols, ethers, and benzene. This solubility property makes it often used as a solvent in organic synthesis, coatings, inks, etc., which can help the solute to disperse uniformly and form a stable system.
Its volatilization rate is moderate, and it is not extremely fast to cause sudden loss of components, nor is it extremely slow to make drying take too long. After the coating is applied, it can evaporate at a suitable speed, making the coating uniform and flat, and the film-forming quality is quite good.
In addition, its flash point is about 56 ° C, and there is a risk of combustion and explosion in case of open flames and hot topics. When storing and using, be sure to keep away from fire and heat sources, and strictly follow safety procedures to prevent the risk of accidents.
What is the chemistry of Diisobutyl Ketone?
Diisobutyl ketone, its shape is transparent, the taste is light and slightly fragrant. Stable at room temperature, not easy to explode, but also dangerous in case of open flames and hot topics.
Melt -46.0 ° C, boil 168.1 ° C. It is insoluble in water, but easily soluble in organic solvents such as alcohols and ethers. This is an excellent organic solvent and is widely used in coatings, inks, adhesives and other industries.
It is moderately volatile and can enter the body through breathing and skin. Although it is low toxic, it is also harmful to health after prolonged or high-concentration contact. It is irritating to the eyes and respiratory tract, and inhalation can cause dizziness, nausea and fatigue.
When storing and using, it should be placed in a cool and ventilated place, away from fire and heat sources, and stored separately from oxidants, acids, etc. Safety procedures must be strictly followed and appropriate protective equipment should be used to ensure safety.
What are the precautions for using Diisobutyl Ketone?
For diisobutyl ketone, there are various things to pay attention to when using it. It is flammable, so it should be kept away from fire and heat sources, stored in a cool and well-ventilated place, and protected from direct sunlight to prevent fire and explosion.
Also, the steam or fog of diisobutyl ketone can irritate the eyes, respiratory tract, or even cause central nervous system suppression. Therefore, it is necessary to prepare suitable protection when using it. Operators wear protective clothing, protective gloves, and if necessary, a self-priming filter gas mask to prevent steam inhalation and damage to health.
Furthermore, after use, the container should not be neglected. It should be properly disposed of and must not be discarded at will to prevent environmental pollution. If you accidentally leak during operation, quickly cut off the fire source, evacuate personnel to a safe place, and isolate them. Small leaks can be absorbed by inert materials such as sand and vermiculite; if there are large leaks, you need to build a dike or dig a pit for containment, and then transfer it to a tanker or a special collector with an explosion-proof pump for recycling or transportation to a waste treatment site for disposal.
In short, with diisobutyl ketone, you must be careful and follow safety procedures, so as to ensure safe operation, avoid accidents, and protect the environment from harm.
What are the production methods of Diisobutyl Ketone?
Diisobutyl ketone, as well as organic compounds, can be prepared by various methods.
One is the isopropanol method. With isopropanol as raw material, under the action of a special catalyst, after the dehydrogenation step, acetone is first formed. Then, acetone is condensed under specific conditions to form diacetone alcohol. Diacetone alcohol is dehydrated and hydrogenated, and finally diisobutyl ketone can be obtained. In this way, isopropanol has a wide source, the cost is relatively easy, and the process is relatively mature, which is a common preparation method.
The second is the isobutanol method. With the help of the dehydrogenation catalyst, isobutanol is first converted into isobutyraldehyde. Isobutyraldehyde condenses with each other to obtain enaldehyde intermediates. This intermediate can be hydrogenated to produce diisobutyl ketone. The raw materials involved in the isobutanol method are also easy to purchase, and the purity of the product is quite high, which is also used in industrial preparation.
The third is acetone condensation. Using acetone as the starting material, in the environment of basic catalyst, two molecules of acetone condensate to form diacetone alcohol. Diacetone alcohol is dehydrated to obtain isopropylene acetone, and then hydrogenated to obtain diisobutyl ketone. The advantage of this path is that acetone raw materials are common and the process operation is easier to control.
Each method for preparing diisobutyl ketone has its own length. It is necessary to carefully choose the appropriate preparation process according to various factors such as the availability of raw materials, cost considerations, and product quality requirements.
