What are the Physical Properties of Methyl Cinnamate?
Methyl cinnamate is an organic compound with unique physical properties. It is a colorless to light yellow oily liquid at room temperature, with a fragrant smell and an aroma similar to cinnamon.
Looking at its melting and boiling point, the melting point is about -12 ° C, and the boiling point is 260-262 ° C. This boiling point characteristic makes it mostly liquid at common ambient temperatures, and because of its high boiling point, it is relatively stable, and it is not easy to evaporate and evaporate easily.
Re-discussion of solubility, methyl cinnamate is insoluble in water, but soluble in many organic solvents, such as ethanol, ether, chloroform, etc. This difference in solubility is due to its molecular structural characteristics. The molecule contains benzene ring, ester group and other groups, so that it can interact with organic solvent molecules by the principle of similar miscibility, but it is difficult to form an effective effect with water molecules, so it is insoluble in water.
Its density is about 1.091-1.096 g/cm ³, which is slightly larger than that of water, so that when mixed with water, methyl cinnamate will sink to the bottom.
The refractive index of methyl cinnamate is about 1.559-1.561. The refractive index is an important optical property of the substance. This value indicates that it has a specific refractive ability to light, which has certain reference value in the field of optical materials or analysis and detection.
In summary, methyl cinnamate is widely used in many fields such as fragrances, medicine, and chemical industry due to its unique physical properties. For example, its aroma can be used to prepare flavors and fragrances, and its solubility and other characteristics can be used as solvents or raw materials in organic synthesis reactions.
How to Prepare Methyl Cinnamate
The method of making methyl cinnamate should follow the following steps. The first step is to prepare cinnamic acid and methanol as raw materials. Cinnamic acid is an aromatic organic acid, and methanol is a common alcohol reagent.
In a clean reaction vessel, add an appropriate amount of cinnamic acid and methanol. In order to promote this reaction, a catalyst is often added, and sulfuric acid and the like can be used for this purpose. It can increase the reaction rate and make the reaction reach equilibrium faster.
Properly place the reaction vessel and connect it to a condensing device. The main purpose of this device is to condense and reflux the evaporated methanol and other volatiles during the reaction, and re-enter the reaction system to avoid loss of raw materials and ensure sufficient reaction.
Next, use an appropriate heat source to heat up the reaction system. Maintain a certain temperature and time to fully react cinnamic acid with methanol. This reaction is an esterification reaction. During the process, the carboxyl group of cinnamic acid and the hydroxyl group of methanol are condensed to remove one molecule of water to form methyl cinnamate.
After the reaction is completed, wait for the system to be slightly cold and then deal with it. The product can be purified by separation and distillation. Separation can separate the aqueous layer and insoluble impurities, and distillation can obtain pure methyl cinnamate according to the different boiling points of each component. After such steps, the required methyl cinnamate can be obtained.
What are the precautions for Methyl Cinnamate in storage and transportation?
When storing and transporting methyl cinnamate, many matters need to be paid attention to.
The first one to bear the brunt is the control of temperature. This substance can easily change its properties when heated, or even cause adverse conditions such as decomposition. Therefore, when storing, it is advisable to choose a cool place, and the temperature should usually be controlled between 15 and 25 degrees Celsius. It must not be placed in a place with direct sunlight or in an environment with excessive temperature, such as a heater or a steam pipe. During transportation, it is also necessary to prevent it from being exposed to high temperature. If transported in hot summer, the vehicle needs to be equipped with an effective heat insulation and cooling device.
Furthermore, the impact of humidity should not be underestimated. Moisture can easily cause methyl cinnamate to get damp or cause its quality to decline. The storage place must be kept dry, and the relative humidity should be maintained between 40% and 60%. The packaging should be tightly sealed to prevent the intrusion of external moisture. The transportation vehicle should also ensure that it is dry and free from the risk of rain leakage. If it passes through high humidity, it is even more important to strengthen protection.
Stable packaging is also the key. Methyl cinnamate is a chemical product, and its packaging must be strong and durable to resist a certain degree of collision and extrusion. When storing, it should be placed properly to avoid dumping and rolling. Before transportation, carefully check whether the packaging is intact, and replace it in time if there is any damage. During loading and unloading, the operator should also handle it with care and must not operate it brutally.
In addition, pay attention to its isolation from other substances. Methyl cinnamate should not be mixed or mixed with oxidants, strong acids, strong alkalis and other substances. Due to its active chemical properties, contact with these substances can easily cause chemical reactions, or cause serious accidents such as combustion and explosion. Storage warehouses and transportation vehicles should be strictly classified and stored to ensure isolation from each other.
At the same time, safety signs should not be ignored. Whether it is a storage place or a transportation vehicle, clear and clear safety signs should be posted, such as "flammable" "handle with care" "moisture-proof" and other signs, so that relevant personnel can quickly identify and take appropriate protective measures. And managers and transportation personnel should be familiar with the characteristics of methyl cinnamate and emergency treatment methods to prepare for emergencies.
Effects of Methyl Cinnamate on Human Health
Methyl cinnamate, the impact of human health, although ancient times did not elaborate on this thing, but based on today's theory, it can be briefly described.
This thing may have fragrant properties, commonly found in spices, pleasant smell, make people happy, or can relieve anxiety and relieve anxiety. And it is also used in the field of skin care, or can help the skin resist external harm, such as protecting the epidermis, making it moist and firm.
From the perspective of pharmacology, studies have shown that it may have a certain anti-inflammatory effect. Inflammation, the beginning or accompanying signs of many diseases. Methyl cinnamate can inhibit the reaction of inflammation, block the release of inflammatory factors, and relieve inflammation in the body, such as joint inflammation, intestinal inflammation, or soothing effect.
However, it should not be ignored. Although it has many benefits, if excessive exposure or ingestion, it may also be harmful. The human body has limited tolerance, exceeding its limit, or causing skin discomfort, such as rash, itching; or disturbing the normal transportation and transformation of the internal organs, affecting the function of the internal organs. Therefore, when using products containing this substance, it is necessary to take moderation, so that you can enjoy its benefits to the fullest, avoid its harm, and protect your health. Kangtai.
