In the fragrance industry, it is quite popular. Because of its unique and attractive aroma, it is often added to various perfumes as a fragrance component, which can endow perfumes with a rich, elegant and layered fragrance, making the aroma richer and longer lasting. The ancients said: "Fragrance, pleasing to the heart, pleasing to the god." Benzyl cinnamate plays a key role in the preparation of fragrances with its aroma, for the purpose of pleasing the senses.
In the food industry, it also has its own shadow. It can be used as a food fragrance to add flavor to food. In the production of sweets, beverages and other foods, adding an appropriate amount can give the food a unique flavor and enhance the attractiveness of the food, just as the old saying goes: "Those who taste beautiful can increase appetite and delight the stomach."
Furthermore, in the field of medicine, benzyl cinnamate also shows certain medicinal potential. Studies have shown that it may have anti-inflammatory and antibacterial properties, and can be used as a raw material or auxiliary ingredient for drug research and development to help human health, which is in line with the concept of "medicine is benevolent, healing and saving people".
In addition, in the cosmetics industry, it can be used to improve the texture and stability of cosmetics, and because of its aroma, it can enhance the experience of using cosmetics, making users happy, in line with the common sense of "beauty, everyone has it".
What are the physical properties of Benzyl Cinnamate?
Benzyl cinnamate is an organic compound. Its physical properties are quite characteristic.
Looking at its form, at room temperature, it is mostly white to light yellow crystalline powder, delicate and uniform, and has a smooth feel to the touch. This form is easy to store and use, and it is easy to mix with others in many preparations.
When it comes to smell, benzyl cinnamate exudes a mild and charming aroma, just like spring blooming flowers, blending sweet and elegant scents, just like the fragrance of cinnamon and the unique fragrance of benzyl. It is often favored by perfumers and can add a unique fragrance in the perfume and fragrance industry. < Br >
Furthermore, its melting point is between 39 and 42 degrees Celsius. When the temperature gradually rises, the substance slowly melts from solid to liquid. This property is crucial in some processes that require precise temperature control, and is related to the quality and properties of the product. And its boiling point is about 350 degrees Celsius. Its high boiling point indicates that it has good thermal stability. In high temperature environments, it can also maintain the relative stability of its own chemical structure and is not easy to evaporate and dissipate. Therefore, it can exert its inherent effectiveness in some high temperature processes.
In addition, benzyl cinnamate is slightly soluble in water, but easily soluble in organic solvents such as ethanol and ether. This difference in solubility makes it widely used in coatings, inks, and other industries as a medium, assisting in uniform dispersion and improving product performance and quality.
What are the chemical properties of Benzyl Cinnamate?
Benzyl cinnamate is an organic compound. It is mild in nature and has a fragrant fragrance. It is commonly found in the fragrance and cosmetic industries.
From the physical and chemical properties, benzyl cinnamate is a colorless to light yellow oily liquid or crystalline solid. The melting point is about 39-42 ° C, and the boiling point is around 370 ° C. It is insoluble in water, but soluble in organic solvents such as ethanol and ether. In its chemical structure, benzyl is connected to the cinnamic acid group, giving it a certain stability.
In terms of chemical activity, the carbon-carbon double bond of the cinnamic acid part in benzyl cinnamate allows the compound to participate in the addition reaction. Under suitable reagents and conditions, double bonds can be added to halogens, hydrogen halides, etc., enriching their chemical derivation paths.
In the fragrance application field, because of its sweet, warm and floral aroma, it is often used as a setting agent to add depth and durability to perfumes and flavors. In cosmetics, it not only provides a pleasant aroma, but its mild properties usually do not cause excessive irritation to the skin, so it is widely used in various skin care and beauty products.
In addition, benzyl cinnamate has also emerged in some pharmaceutical research. Although it is not a mainstream drug ingredient, its unique chemical structure provides new directions and possibilities for drug synthesis and pharmacological research.
What are the production methods of Benzyl Cinnamate?
Benzyl cinnamate is prepared by various methods.
First, cinnamic acid and benzyl alcohol are used as raw materials and can be prepared by esterification reaction. This is a common method. Concentrated sulfuric acid is used as a catalyst to esterify the two at an appropriate temperature. However, concentrated sulfuric acid is highly corrosive, damaging to equipment, and has many side reactions. During the reaction, precise temperature control is required to ensure that the reaction proceeds in the direction of generating benzyl cinnamate.
Second, the acyl chloride method is used. Cinnamic acid is first made into cinnamyl chloride, and then reacted with benzyl alcohol. In this process, cinnamic acid interacts with thionyl chloride and other reagents to form cinnamyl chloride, and then reacts with benzyl alcohol in the presence of alkali. This method has high reactivity and considerable yield. However, thionyl chloride and other reagents are irritating and corrosive, and the operation needs to be cautious. It should be carried out in a well-ventilated place, and the follow-up treatment needs to be fine.
Third, transesterification method. Using cinnamic acid ester and benzyl alcohol as raw materials, transesterification reaction is carried out under the action of catalyst. This catalyst can be organotin, etc. The advantage of this method is that the conditions are relatively mild, but the activity and selectivity of the catalyst are quite high. During the reaction, the reaction process needs to be closely monitored and the reaction conditions adjusted in time to achieve the ideal yield. < Br >
The methods for preparing benzyl cinnamate have their own advantages and disadvantages. When implementing, the appropriate method should be carefully selected according to many factors such as the availability of raw materials, equipment conditions, and cost considerations.
What is the price range of Benzyl Cinnamate in the market?
The price of benzyl cinnamate in the market varies depending on the quality, source, quantity, etc. If a good product has a positive source and a prosperous market, its price is high; if the quality is flat and the supply is sufficient, the price is flat.
In the past, the price of common benzyl cinnamate is about tens to hundreds of dollars per catty. If it is a refined product, it is used for high-demand industries, such as exquisite balms, elegant finishes, etc., its price can reach hundreds of dollars per catty.
However, the market situation is changeable, and the price also fluctuates. The origin is abundant, the transportation road is blocked, and the change of the government can all make the price different. Therefore, if you want to know the exact price, you should ask the cities, shops, or carefully observe the current price report to get an accurate number. Although it is difficult to determine the exact value, according to past examples and market conditions, the price is mostly in the range of tens to hundreds of dollars per catty.
