What are the Physical Properties of Ethyl Hexanoic Acid?
2-Ethylhexanoic acid is an organic compound. It has many physical properties, as detailed below:
Under normal temperature and pressure, 2-ethylhexanoic acid is a colorless oily liquid with a special odor. This appearance characteristic is the first manifestation of its physical properties.
As for the melting point, it is about -80 ° C. The lower melting point allows the substance to maintain a liquid state in a relatively low temperature environment and exhibit a certain low temperature fluidity.
In terms of boiling point, it is about 228-230 ° C. The higher boiling point indicates that the intermolecular force is relatively strong, and more energy is required to transform it from liquid to gaseous.
The density is about 0.9036g/cm ³ (20 ° C). This density value is slightly smaller than that of water, so if it is mixed with water, it will float on the water surface.
Solubility is also an important physical property. 2-ethylhexanoic acid is slightly soluble in water, but miscible with organic solvents such as alcohols, ethers, and chloroform. This difference in solubility is due to the fact that there are both hydrophobic alkyl and hydrophilic carboxyl moieties in its molecular structure. However, in general, hydrophobicity is dominant, resulting in limited solubility in water and good miscibility with organic solvents.
In addition, the physical properties such as vapor pressure and surface tension of 2-ethylhexanoic acid also affect its behavior in different environments. Its vapor pressure will increase with temperature. At a certain temperature, the magnitude of vapor pressure depends on its susceptibility to volatilization; surface tension affects its behavior on the surface of liquids and interactions with other surfaces.
In summary, the physical properties of 2-ethylhexanoic acid are diverse, and these properties are interrelated to determine their existence and behavior in various scenarios.
Is 2-Ethyl Hexanoic Acid Chemically Stable?
2-Ethylhexanoic acid is said to be stable under normal conditions. It has carboxylic acid generality, and the carboxyl group is active. It can form salts with bases and react with alcohols in esterification.
Looking at its structure, ethyl is connected to hexyl, and the existence of side chains causes molecules to have a certain spatial resistance, which affects their activity in some reactions. However, the spatial resistance also makes it more stable than straight-chain carboxylic acids in some cases.
If the environment is mild and there are no extreme conditions such as strong oxidizing agents, strong acids and bases, or high temperatures, 2-ethylhexanoic acid can mostly maintain a stable state. In the air, if there is no initiator, it is difficult to spontaneously produce significant changes.
When encountering strong oxidants, the carboxyl group may be oxidized, and the structure is broken. When strong acids and bases are strong, the reaction intensifies and the properties change. And when the temperature increases, the molecular movement intensifies, the reactivity enhances, and the stability gradually weakens.
In short, 2-ethylhexanoic acid is usually quite stable, but under certain extreme conditions, its chemical properties may change and cannot be generalized.
2-Ethyl Hexanoic Acid What to pay attention to when storing
2-Ethylhexanoic acid is an organic compound. When storing, many matters need to be paid attention to.
First, it is critical to the temperature and humidity requirements of the storage environment. This substance should be stored in a cool place. If the temperature is too high, it will easily evaporate and intensify, or cause chemical reactions. The ideal temperature is about 20 to 25 degrees Celsius. Humidity also needs to be controlled. Excessive humidity may make the packaging damp, which will affect the purity of the substance. Generally, the humidity should be maintained at 40% to 60%.
Second, the choice of storage containers is extremely important. When choosing corrosion-resistant materials, such as glass and containers made of specific plastic materials. 2-Ethylhexanoic acid has a certain acidity. If the container is not resistant to corrosion, it is easy to react with the container and pollute the substance.
In addition, the storage place must be kept well ventilated. The volatile gaseous components of this substance may be irritating to a certain extent. In places with poor ventilation, gas accumulation, or harm to human health, there are also potential safety hazards.
In addition, it should be kept away from fire sources, heat sources and oxidants. 2-Ethylhexanoic acid is flammable, and there is a risk of combustion and explosion in case of open flames and hot topics. And contact with oxidants can easily cause violent reactions, so it must be isolated from them when storing.
Repeat, the storage area should be clearly marked, indicating the name of the substance, characteristics, hazards and emergency treatment methods. In this way, in the event of an accident, relevant personnel can quickly know the situation and take appropriate measures.
Finally, regularly check the stored 2-ethylhexanoic acid. Check whether the packaging is in good condition, whether there is any leakage, and detect whether the purity and quality of the substance have changed. If any problems are found, deal with them in time to ensure storage safety.
2-Ethyl Hexanoic Acid Production Methods
The preparation of 2-ethyl hexanoic acid (2-ethyl + Hexanoic + Acid) has been done in several ways in the past.
One is to use butyraldehyde as the starting material and form 2-ethylhexenal through condensation reaction. Butyraldehyde is condensed with each other under specific catalysts and suitable conditions, and the chemical bonds are rearranged and combined. The activity of the aldehyde group guides the reaction process, and then the alkenal is obtained. Then 2-ethylhexenal is catalyzed for hydrogenation, so that both the alkenyl bond and the aldehyde group are reduced, and finally 2-ethylhexenoic acid is formed. In this process, the hydrogenation conditions are very critical, and the choice of catalyst and the regulation of temperature and pressure are all related to the purity and yield of the product.
The second method is prepared by oxidation reaction with n-octanol as raw material. Under the action of suitable oxidants, the hydroxyl group is oxidized to the carboxyl group, but the degree of oxidation needs to be precisely controlled to prevent excessive oxidation from causing the product to be complex and impure. Commonly used oxidants, such as specific metal salts and organic peroxides, have different oxidation capabilities and selectivity, and need to be selected according to the actual situation.
Furthermore, with 2-ethylhexanol as the starting material, it can also be prepared by catalytic oxidation. A specific metal oxide is selected as the catalyst, and the hydroxyl group of 2-ethylhexanol is oxidized under an aerobic environment and appropriate temperature, and gradually converted into 2-ethylhexanoic acid. During this process, the activity and stability of the catalyst have a profound impact on the reaction, and the oxygen concentration and temperature in the reaction system also need to be carefully adjusted to ensure that the reaction is efficient and directional, and high-purity 2-ethylhexanoic acid products are obtained.
