In the field of medicine, it can also be used. Modern research has gradually revealed that it has certain biological activities, or contains antibacterial and anti-inflammatory properties. Doctors may use its such properties to explore new drug therapies and treat diseases for patients. However, the research in this area is still on the way, and more research is needed to clarify the details.
In the process of organic synthesis, α-methyl cinnamaldehyde is the key raw material. Organic synthesis craftsmen can use its structural characteristics to construct complex organic molecules through various chemical reactions, such as addition, oxidation, reduction, etc. It can produce fine chemicals, pesticide intermediates, etc., expanding many possibilities for the chemical industry. In short, α-methyl cinnamaldehyde has important functions in many fields such as fragrance, medicine, and organic synthesis, and has broad prospects.

The physical properties of α-methyl cinnamaldehyde are as follows:
Under normal conditions, this substance is a light yellow to yellow liquid with a strong aroma. Its aroma is rich and unique, resembling a cinnamon-like spicy aroma, and it contains a fresh floral aroma. The aroma is very long-lasting, which is very important in fragrance preparation.
Its boiling point is about 264-266 ° C. Under this temperature condition, α-methyl cinnamaldehyde converts from liquid to gaseous state. The melting point is about -15 ° C. When the temperature drops below this point, it solidifies from liquid to solid state.
The relative density is between 1.011-1.019, indicating that it is slightly heavier than the homogeneous water. The refractive index is in the range of 1.572-1.578, and when light passes through α-methyl cinnamaldehyde, it will be refracted according to this range.
α-methyl cinnamaldehyde is slightly soluble in water, but it can be miscible with organic solvents such as ethanol and ether. This dissolution property makes it well mixed with corresponding solvents in the preparation of different formulations, which is convenient for applications in flavors, cosmetics, food additives and other fields. Its chemical stability is good to a certain extent, but under extreme conditions such as high temperature, strong acid and alkali, or chemical reactions occur, causing its structure and properties to change.

Alpha-methylcinnamaldehyde, Chinese name α-methyl cinnamaldehyde, is one of the organic compounds. It is active and has many unique chemical properties.
This substance contains carbon-carbon double bonds and aldehyde groups, so its chemical activity is quite high. Let's talk about aldehyde groups first, which can participate in many reactions. In oxidation reactions, when encountering strong oxidants, such as acidic potassium permanganate, aldehyde groups are easily oxidized to carboxyl groups, so they become α-methyl cinnamic acid; if treated with mild oxidants, such as Torun reagent or Feilin reagent, aldehyde groups will be oxidized to carboxylic salts, and silver mirrors or brick-red precipitation will be precipitated respectively. This property is often used as a qualitative test for aldehyde groups.
And due to the carbon-containing carbon double bond, α-methyl cinnamaldehyde can undergo an addition reaction. When added with hydrogen, under the action of a suitable catalyst, both the carbon-carbon double bond and the aldehyde group can be hydrogenated to produce α-methylphenylpropanol; when added with hydrogen halide, the Markov rule is followed. Hydrogen atoms are added to double-bonded carbon atoms containing more hydrogen, and halogen atoms are added to those containing less hydrogen to form halogenated phenylpropanaldehyde derivatives. And the carbon-carbon double bond can also carry out a polymerization reaction. Under the action of the initiator, the double bonds of many α-methyl cinnamaldehyde molecules open, connect with each other, and polymerize into polymer compounds.
In addition, the aldehyde group of α-methyl cinnamaldehyde can be condensed with compounds containing active hydrogen. For example, under acid catalysis with alcohols, semi-acetals are formed first, and then acetals are formed. This reaction is often used to protect aldehyde groups in organic synthesis. It can also condensate with amines to form Schiff bases, which are widely used in the field of medicine and material synthesis.
The chemical properties of α-methyl cinnamaldehyde are determined by its functional groups, and these properties make it important in many fields such as organic synthesis, fragrances, and medicine.

Alpha-methylcinnamaldehyde (α-methylcinnamaldehyde) is also an organic compound. The common methods for its preparation have the following numbers.
First, benzaldehyde and propionaldehyde are used as raw materials and prepared by condensation reaction. This reaction often requires a base as a catalyst, such as sodium hydroxide or potassium hydroxide. At an appropriate temperature and reaction time, the carbonyl group of benzaldehyde and the α-hydrogen of propionaldehyde are condensed to obtain α-methylcinnamaldehyde. The reaction mechanism is that the base causes the α-hydrogen of propionaldehyde to leave, forming anion, which nucleophilic addition to the carbonyl group of benzaldehyde, and then dehydrates to obtain the target product. < Br >
Second, cinnamaldehyde is used as raw material and prepared by methylation reaction. Commonly used methylation reagents such as iodomethane are methylated at specific positions on the double bond or benzene ring of cinnamaldehyde in alkaline conditions and appropriate solvents to generate α-methyl cinnamaldehyde. This process requires precise control of the reaction conditions. Because the selectivity of methylation positions is quite critical, improper conditions can easily lead to side reactions, affecting the purity and yield of the product.
Third, styrene derivatives and formaldehyde are used as raw materials. First, the styrene derivative reacts with formaldehyde under the action of a specific catalyst to form an intermediate product, and then further converts and modifies to obtain α-methyl cinnamaldehyde. This method requires careful screening and preparation of the catalyst to ensure that the reaction is efficient and selective.
When preparing α-methyl cinnamaldehyde, it is necessary to carefully control the reaction conditions, such as temperature, pH, ratio of reactants, reaction time, etc., which have a great impact on the yield and purity of the product. At the same time, the separation and purification steps after the reaction cannot be ignored. Distillation, extraction, recrystallization and other means are commonly used to obtain high-purity α-methyl cinnamaldehyde.

For alpha-methyl cinnamaldehyde, there are several ends that should be added when storing and transporting it.
The first storage environment. This substance should be stored in a cool, dry and well-ventilated place. If it is in a warm and humid place, it may deteriorate. Cover the temperature can promote the rate of its chemical reaction, and the humid gas may cause its hydrolysis and other changes. Therefore, it is necessary to choose a cool, dry and well-ventilated place to ensure the stability of its quality.
The second point is the importance of packaging. The packaging must be tight to prevent leakage. Because it is volatile and irritating, if it leaks outside, it will not only damage itself, but also endanger the surrounding environment and human health. It is commonly used in airtight containers to ensure that there is no gas or liquid leakage.
When transporting, it should also be cautious. Keep away from fire and heat sources to avoid the risk of ignition and explosion. Because of its flammability, it will be dangerous in case of open flames and hot topics. And during transportation, strive to be smooth to prevent it from dumping, colliding, and causing package damage and leakage.
Furthermore, when handling, the operator must wear appropriate protective equipment. Such as gas masks, protective gloves, etc., because alpha-methyl cinnamaldehyde is irritating to the eyes, respiratory tract and skin, it is easy to be injured if it is not protected.
All these ends are for the storage and transportation of alpha-methyl cinnamaldehyde, and should not be ignored in order to ensure its quality and safety.
