Cinnamic Aldehyde

Cinnamic Alaldehyde is an important organic compound with a wide range of uses.
In the field of fragrances, cinnamic aldehyde has a significant effect. Because of its unique spicy and cinnamon aroma, it is often used as a spice to add to many products. In the food industry, it can increase the flavor of food, such as bread, cakes and other baked goods. It can give it an attractive aroma, enhance the taste, and stimulate the appetite. In the cosmetics and perfume industry, its aroma can add a unique flavor to the product. It is a commonly used fragrance ingredient for perfumers and contributes to a unique fragrance.
In medicine, cinnamic aldehyde also has important functions. Studies have shown that it has antibacterial and anti-inflammatory effects. It can inhibit the growth of Escherichia coli, Staphylococcus aureus and other bacteria, so it is used in pharmaceutical preparations or as an antimicrobial agent. Its anti-inflammatory properties or adjuvant treatment for inflammation-related diseases are beneficial for relieving local inflammatory reactions in the body.
In the agricultural field, cinnamaldehyde can be used as a natural pesticide. Because of its antibacterial properties, it can prevent plants from being attacked by pathogens and reduce the incidence of agricultural crop diseases. At the same time, it has a repellent effect on some pests, which can reduce the harm of pests to crops, help the development of green and environmentally friendly agriculture, and reduce the use of chemical pesticides.
In industry, cinnamaldehyde can be used to synthesize Its molecular structure has active groups, which can be chemically reacted to make additives for industrial products such as plastics and rubber, and improve product properties, such as enhancing plastic toughness and improving rubber aging resistance.
It can be seen that cinnamaldehyde has important uses in many fields such as fragrances, medicine, agriculture, industry, etc., and has far-reaching impact on people's lives and industrial production.

Cinnamic Alaldehyde is a common organic compound with unique physical properties. Its properties are colorless to light yellow liquid, which can be observed at room temperature and pressure. Looking at its color, it is clear and light-colored, just like the first light in the morning, pure and soft.
Smell, cinnamic aldehyde emits a rich, warm and spicy smell, similar to the fragrance of cinnamon. This fragrance is unique and fresh, and can instantly stir the sense of smell, which is impressive, as if you are in a perfume-filled environment.
Its boiling point is about 253-254 ° C. This property makes cinnamic aldehyde change from liquid to gaseous at a specific temperature. If the heat is used as a metaphor, when the heat reaches this specific point, cinnamaldehyde is like a smart feather, rising lightly. The melting point is about -7.5 ° C, which means that when the temperature drops to this point, cinnamaldehyde will condense from liquid to solid, just like water turns into ice when it meets cold, and its shape changes.
The density of cinnamaldehyde is about 1.049-1.052 g/cm ³, which is slightly heavier than water. If it is placed in one place with water, it can be seen that it is like a stable stone, slowly sinking to the bottom of the water.
In terms of solubility, cinnamaldehyde is slightly soluble in water, but can be well miscible with organic solvents such as ethanol and ether. Like being a little shy in water, incorporating organic solvents is like a duck to water, and it can be closely integrated with it.
These physical properties not only determine the application of cinnamaldehyde in various fields, but also make it unique in the chemical world, providing a foundation and possibility for many studies and practices.

Cinnamaldehyde is also a chemical substance. When hiding, several things should be paid attention to.
First, it is important to avoid light. This aldehyde is sensitive to light, and if exposed to light, it is easy to cause its qualitative change, damage its purity, and reduce its effectiveness. Therefore, it should be hidden in a dark room, or stored in a light-shielding device, so that it is far away from light disturbance.
Second, low temperature is appropriate. Cinnamaldehyde is uneasy when heated, and high temperature can easily cause it to evaporate and decompose. It should be placed in a cool place to keep its stability, usually two to eight degrees is the best environment.
Third, the seal must be strict. Its gas is easily dissipated, and it can be oxidized and caused by long-term contact with the air. It must be kept in a secret container to prevent the escape of gas and the invasion of oxygen.
Fourth, keep away from water and fire. This aldehyde is flammable, and it is dangerous in case of fire; and it meets with water or moisture, or reacts adversely. When stored in a dry, fire-free place.
Fifth, isolate sundries. Do not store with acid, alkali and other easily reactive substances to prevent chemical changes and maintain its purity. Following this number, you can store cinnamon aldehyde well to keep its performance constant and ready for use.

There are many ancient books on the preparation of cinnamic aldehyde. There are two methods, one is a natural extraction method, and the other is a chemical synthesis method.
The natural extraction method is extracted from cinnamon skin, leaves and other plants by distillation and extraction. First, the cinnamic raw materials are selected, crushed, placed in a distiller, filled with an appropriate amount of water, and heated to a boil, so that the cinnamic aldehyde escapes with the water vapor. After condensation, oil and water are separated to obtain a crude product, and then distilled to obtain a pure product. This is an ancient method. The cinnamic aldehyde obtained has a natural fragrance, but the raw materials are rare, the extraction is difficult, and the yield is quite low.
Chemical synthesis method, commonly used is Perkin reaction. Using benzaldehyde and acetic anhydride as raw materials, under the catalysis of sodium acetate, heated to reflux, produce cinnamic acid, and then reduced, cinnamaldehyde can be obtained. The reaction is as follows: benzaldehyde and acetic anhydride, catalyzed by sodium acetate, in a heated environment, the aldehyde group of benzaldehyde and the α-hydrogen of acetic anhydride undergo a condensation reaction to form cinnamic acid. After reducing agents such as lithium aluminum hydride, the carboxyl group of cinnamic acid is reduced to an aldehyde group, and then cinnamaldehyde is obtained. The raw materials of this method are easy to obtain and the yield is quite high, but the purity of the product may be inferior to that of natural extractors.
It is also prepared by other synthetic methods, such as styrene, carbon monoxide, and hydrogen. Under the action of a catalyst, the hydroformylation reaction can also obtain cinnamaldehyde. However, all kinds of chemical synthesis methods require attention to the control of reaction conditions to ensure that the quality and quantity of the products are excellent.

Cinnamaldehyde, the effect of this substance on human health, although it has not been detailed in ancient times, it can also be obtained from today's scientific research.
Cinnamaldehyde has a unique aroma and is commonly found in cinnamon and other substances. Its impact on human health has many aspects. First, it has good antibacterial power. It can resist a variety of pathogens, such as Escherichia coli, Staphylococcus aureus, etc., which is beneficial for maintaining the balance of human microecology and can help the human body resist the invasion of pathogens and reduce the risk of disease. Second, it has antioxidant effect. It can remove free radicals in the body, slow down the aging of cells, protect cells from damage, and is beneficial to the state of the skin and the overall vitality of the body. Third, it also has an effect on the digestive system. It can promote the secretion of digestive juices, increase the peristalsis of the stomach and intestines, help the digestion and absorption of food, and have a complementary effect on the health of the spleen and stomach.
However, those who need to pay attention, although cinnamaldehyde is good for health, excessive intake may also cause discomfort. If people come into contact with or consume too much, it may cause skin allergies, gastrointestinal discomfort, etc. Therefore, when using this product daily, it is advisable to do it in moderation to get its benefits and avoid its harm, which is the right way to maintain health.
