What are the main uses of Benzyl Cinnamate?
Benzyl cinnamate has a wide range of uses. In the genus of fragrances, it is very useful. Because of its unique aroma, it is often used in fragrances, adding a rich fragrance to perfumes, aromatherapy and other substances, which can give the fragrance an elegant and long rhyme, and the user seems to be in a state of fragrance.
In daily chemical products, it is also common. Such as skin care creams, shampoos, etc., adding this increases the aroma of the product, enhances its quality and charm, and helps the product to be more competitive in the market and is favored by consumers.
Furthermore, in the field of medicine, it also has certain uses. Although it is not the main drug, it can be used as a pharmaceutical excipient, assisting in drug molding, improving drug taste or stability, etc. Or assisting in drug release, making the drug effect more durable and stable, which is beneficial to patient health.
It is also added to some industrial products, such as coatings and inks. It can improve product odor, and may have a positive impact on film-forming performance, etc., making product performance better and wider application range.
What are the physical properties of Benzyl Cinnamate?
Benzyl cinnamate is also an organic compound. It has various physical properties, which are now detailed by you.
In terms of its appearance, it is often a colorless to light yellow oily liquid, with a clear texture and a clear luster. Under the light, it refracts and shines, like morning dew reflecting the sun, clear and pleasing to the eye.
Smell its smell, emitting a cinnamon-like fragrance, rich and elegant, like being in a garden of vanilla, the aroma is subtle and long, lingering, and has a unique charm.
As for the melting point, it is between 22 and 24 degrees Celsius. Just like the critical point between the cold of spring and the beginning of spring warmth, near this temperature, this substance subtly transitions between solid and liquid states. When the temperature gradually rises, beyond this domain, it will convert from solid to liquid, such as ice, under the warm sun in spring, and turn into a smart fluid.
The boiling point is 346-348 degrees Celsius. It takes a long time to burn the fire to get enough energy for the molecules to break free from each other and turn into gaseous ascension. The high boiling point shows the strong attractive force between molecules and the relatively stable structure.
The density is about 1.049 - 1.056g/cm ³, which is slightly heavier than water. If placed in water, it is like a stone sink, slowly settling, lying quietly at the bottom of the water, showing its heavy quality.
In terms of solubility, it is difficult to dissolve in water, and it is difficult to form an effective interaction with water molecules due to the characteristics of its molecular structure. However, in organic solvents, such as ethanol, ether, chloroform, etc., it can be well miscible. Like a duck in water, the two blend seamlessly, forming a uniform and stable system. This solubility makes it easy to use in organic synthesis and related fields.
Is Benzyl Cinnamate Chemically Stable?
Benzyl cinnamate ester, its chemical properties are relatively stable. Looking at this compound, its structure contains benzyl and cinnamate ester groups, and the interaction between the two causes it to have specific chemical properties.
Benzyl moiety, benzene ring is connected to methylene, and the conjugate system of benzene ring gives it a certain stability, and methylene can participate in specific reactions. However, in the structure of benzyl cinnamate ester, affected by the overall structure, the reactivity is limited.
Cinnamate ester group, containing carbon-carbon double bond and ester group. Although the carbon-carbon double bond is reactive and can undergo reactions such as addition, in benzyl cinnamate, its activity is not very high due to the steric resistance and electronic effects of surrounding groups. Ester groups have properties such as hydrolysis, but under normal conditions, if there are no suitable conditions, the hydrolysis rate is rather slow.
At room temperature and pressure, without special reagents and conditions, benzyl cinnamate can maintain a relatively stable state for a long time, and it is not easy to spontaneously produce significant chemical changes. Even under the influence of common factors such as heat and light, its change is relatively slow, and it is difficult to react violently under non-extreme conditions. Therefore, in general, the chemical properties of benzyl cinnamate are relatively stable.
In which industries is Benzyl Cinnamate widely used?
Benzyl cinnamate is widely used in daily chemical, pharmaceutical, fragrance and many other industries.
In daily chemical industry, it is often used in cosmetic preparation. Because of its unique chemical structure and characteristics, it can impart specific efficacy and texture to cosmetics. It can be used as a thickener to improve the rheological properties of cosmetics and make it smoother and more uniform to apply; it can also enhance the shelf life and quality stability of cosmetics by virtue of its own stability, so that products can maintain good quality during the shelf life.
In the field of medicine, benzyl cinnamate plays an important role. Some studies have shown that it may contain certain biological activities, or have potential pharmacological properties such as anti-inflammatory and anti-oxidant properties. Pharmaceutical developers can explore new pharmaceutical active ingredients through chemical modification and research, and develop innovative drugs with the effect of treating specific diseases.
In the fragrance industry, benzyl cinnamate is favored because of its unique aroma. It can emit an elegant and charming fragrance, which can add a unique charm to fragrance blending. Whether it is blending various fragrances such as floral and oriental fragrances, it can give flavors richer layers and lasting fragrance by virtue of its own aroma characteristics, and is widely used in fragrance products such as perfumes and air fresheners.
In short, benzyl cinnamate has shown a variety of uses and important value in many industries. With the progress of science and technology and the deepening of research, its application prospects may be broader.
What are the production methods of Benzyl Cinnamate?
The preparation method of benzyl cinnamate ester is different from the ancient method and the modern method.
In the ancient method, cinnamic acid and benzyl alcohol are often used as the base, supplemented by catalytic agents, to make the esterification reaction of the two. This process requires appropriate temperature control, usually in a certain temperature range, such as sulfuric acid as the catalyst, heating to advance the reaction. However, sulfuric acid is highly corrosive, and there are many side reactions, and the separation of products is also complicated.
This method is more green and efficient. One is the enzyme-catalyzed method, which selects a specific lipase and stimulates the formation of cinnamic acid and benzyl alcohol into esters under mild conditions. This method of enzyme catalysis has strong specificity, few side reactions, and mild reaction conditions, no need for strong heat and strong corrosive agents, and the product is pure and easy to separate.
There is also a method of phase transfer catalysis, which uses the power of a phase transfer catalyst to make the reaction proceed efficiently between the two phases. This catalyst can help the reactants cross the phase boundary, accelerate the reaction, and increase the yield. At the same time, the reaction conditions are broader than the traditional method, and the equipment requirements are not strict.
In addition, the microwave radiation method is also gradually emerging. With the microwave radiation system, the molecular movement can be accelerated, which greatly increases the reaction rate. This method not only shortens the reaction time, but also improves the yield and the product quality.
In summary, each method has its own advantages and disadvantages. When preparing benzyl cinnamate, the preparation method should be carefully selected according to actual needs, such as cost, yield, purity and other factors.
