4 - methylcinnamaldehyde is an organic compound with unique physical properties. It is a light yellow to yellow liquid at room temperature, like a flowing gold liquid, which is pleasing to the eye.
In terms of smell, this substance emits a rich and sweet cinnamon aroma, fragrant and pungent, just like the rich fragrance of cinnamon, which can evoke the pleasant feeling of smell.
The melting point is about 25-28 ° C, just like the melting point of ice, which melts when the temperature rises slightly. The boiling point is 168-170 ° C. When heated, it rises like a cloud and becomes gaseous. The relative density is about 1.044-1.054, which is slightly heavier than water. If placed in water, it seems to sink gold into water. < Br >
It is insoluble in water, such as oil and water are not compatible, but it is soluble in organic solvents such as ethanol and ether. In such solvents, it is like a duck to water and evenly dispersed. The refractive index is between 1.601 and 1.606. When the light passes through, if it is refracted by a prism, the direction changes.
This substance has a certain stability. However, when exposed to light, heat and air, it will also gradually change. If a beauty is baptized over time, the color or smell will be slightly changed. Under suitable storage conditions, its quality can be guaranteed. If it is not stored properly, it may lose its original characteristics.

4 - methylcinnamaldehyde, it is one of the organic compounds. Its shape is a light yellow liquid with fragrance, which is widely used in various fields such as flavors and pharmaceutical chemicals.
In terms of its chemical properties, the first consideration is its functional group characteristics. The compound contains carbon-carbon double bonds and aldehyde groups, which give it unique chemical activity. The carbon-carbon double bond has the property of electrophilic addition, which can react with many electrophilic reagents, such as hydrogen halides and halogens. In case of bromine water, bromine can be added to the double bond, causing the bromine water to fade. This is a common method to verify the carbon-carbon double bond. The activity of
aldehyde groups should not be underestimated. Under the action of weak oxidants such as Torun reagent (silver ammonia solution), the aldehyde group is oxidized to the carboxyl group, and the silver mirror is precipitated at the same time. This is the silver mirror reaction, which is often a landmark reaction for testing the aldehyde group. In case of strong oxidants, such as acidic potassium permanganate solution, not only the aldehyde group is oxidized, but also the carbon-carbon double bond is destroyed.
In addition, the aldehyde group can also undergo a reduction reaction. With hydrogen as the reducing agent, under the action of an appropriate catalyst, the aldehyde group can be reduced to an alcohol hydroxyl group to obtain 4-methylcinnamyl alcohol. < Br >
Furthermore, due to the conjugation of benzene ring with carbon-carbon double bond and aldehyde group in its molecular structure, the electron cloud distribution is more delocalized, which enhances the molecular stability and also affects its reactivity and physical properties. This conjugation system endows the compound with certain ultraviolet absorption characteristics, which can be identified in spectral analysis.
And because of its aromaticity, and the aldehyde group is connected to the benzene ring, which makes its aroma unique, it can be used in the fragrance industry to prepare a variety of flavors to increase the richness and layering of its aroma.

The preparation methods of 4-methyl cinnamaldehyde are generally as follows.
One is the method of using benzaldehyde and 4-methyl styrene as raw materials. Under suitable reaction conditions, the two are condensed to obtain 4-methyl cinnamaldehyde. This reaction requires the selection of suitable catalysts to promote the reaction to the direction of generating the target product. And during the reaction process, factors such as temperature and the proportion of reactants have a significant impact on the yield and selectivity of the reaction. Fine regulation of these conditions can improve the production efficiency of the product.
The second is the way of starting with 4-methylbenzaldehyde and acetaldehyde. In the alkali-catalyzed environment, the condensation reaction of hydroxyaldehyde occurs. The type and amount of base have a great influence on the reaction process. The choice of weak base or strong base will make the reaction rate and product distribution different. During the reaction, properly control the reaction temperature and time to avoid the excessive occurrence of side reactions, and strive to carry out the main reaction efficiently to obtain a higher yield of 4-methyl cinnamaldehyde.
The third is to use cinnamaldehyde as raw material and methylate to prepare 4-methyl cinnamaldehyde. In this process, an appropriate methylation reagent, such as iodomethane, needs to be selected. At the same time, appropriate reaction solvents and catalysts should be selected to ensure that the methylation reaction occurs precisely at the specific location of cinnamaldehyde to generate the required 4-methyl cinnamaldehyde. The pH, temperature and other conditions of the reaction system also need to be carefully controlled to enable the reaction to proceed smoothly and obtain products with excellent purity and yield.
All these preparation methods have their own advantages and disadvantages. In actual production, it is necessary to carefully choose the appropriate method according to specific needs and conditions to achieve the best production effect.
