(This is a question about the chemical properties of 2,4-diene - α - methyl styrene ketone, which is answered in ancient Chinese)
2,4-diene - α - methyl styrene ketone, which has the dual characteristics of alkene and ketone. Its alkene bond can be added. If it encounters hydrohalic acid, according to Markov's rule, the halogen atom is attached to the alkene carbon containing less hydrogen, resulting in halogenated hydrocarbons. It can also meet with bromine water, and the diatom of bromine is added to the alkene bond, causing the bromine water to fade. This is a typical addition characterization of alkenes.
Its carbonyl group is also active. With the ability of nucleophilic addition, in case of alcohols, under the catalysis of acids or bases, it can form ketals. In combination with hydrocyanic acid, the cyanyl group is added to the carbonyl carbon, and its carbon chain is expanded to obtain a new compound containing cyanide group.
And this substance has special stability and electron delocalization due to the existence of the conjugate system. The conjugate state makes its ultraviolet absorption specific, which can be discerned in spectral analysis. And because of the difference in the distribution of electron clouds, its chemical activity is different from that of ordinary enones. The reaction check point and activity are all affected by the conjugation effect.
In the oxidation reaction, the ethylene bond can be broken by strong oxidants such as potassium permanganate, resulting in the breaking of carbon-carbon double bonds, resulting in carboxylic acids or ketones, depending on the reaction conditions. Carbonyl can also be oxidized by weak oxidants such as Torun reagent and Feilin reagent, depending on its structure and reaction environment.

The method of preparing (Alphas) -2,4-diene - α - methyl styrene ketone is as follows:
First take an appropriate amount of methyl styrene and place it in a clean reactor. The kettle needs to be made of special materials, which can withstand suitable temperature and pressure, and the inner surface is smooth to prevent the reaction from adhering to the reactants and causing uneven reaction. Operate in a well-ventilated and temperature-controlled chamber, the temperature of this chamber should be stable in a specific range, so as not to affect the reaction due to sudden temperature changes.
Then, slowly add an appropriate amount of a specific catalyst. This catalyst needs to be purified in a precise way in advance, and its purity will give good reaction effect. When adding time, it should be slow and uniform, and at the same time, it should be stirred at a uniform speed with a delicate mixer, so that the catalyst and methyl styrene are fully mixed, just like fish and water, to promote the initiation of the reaction.
In addition, adjust the temperature of the reactor and gradually raise it to the appropriate temperature. This heating process needs to be handled carefully, just like riding a horse slowly, and it should not be done too hastily. After the required temperature is reached, maintain a constant temperature. At this time, the reactants in the reactor are gradually awakening like sleeping things, undergoing wonderful chemical changes, and the molecules interact and recombine.
During this period, it is necessary to closely observe the process of the reaction. Watch the change of its color and the generation of bubbles, and measure the change of its composition with exquisite instruments. If there is a specific change in color, or the rate of bubbles reaches a certain value, it can be known that the reaction has reached a certain stage.
When the reaction is close to complete, the reaction can be terminated in a proper way. The temperature can be quickly lowered to make the "fire" of the reaction gradually extinguish, just like a shower extinguishing a prairie fire. Then, the product is separated and purified. By distillation, the product is separated from impurities according to the difference in the boiling point of the substance; and then by extraction, pure (Alphas) -2,4-diene - α - methylstyrene ketone.
The whole preparation process requires the operator to be skilled and meticulous, and careful in every step to obtain high-quality products.

28 (Alphas) - 2,4-diene - α - methyl styrene ketone during storage and transportation, there are several points to be careful to keep in mind.
First, this substance is quite sensitive to temperature changes. If the temperature is too high, it may cause chemical reactions, or cause changes in material properties, and even cause safety risks. Therefore, when storing, it should be placed in a cool and ventilated warehouse, the temperature must be controlled within a specific range, and it must not be exposed to high temperature environment. During transportation, you should also pay attention to the surrounding temperature. In case of hot weather, you need to take measures to insulate and cool down to prevent the temperature from getting out of control.
Second, because it has a certain chemical activity, it is easy to react with other chemicals. Therefore, when storing, it must not be stored with oxidizing substances, acids, alkalis, etc. It must be strictly isolated from these substances to prevent interaction and cause danger. The container for transportation also needs to be carefully selected to ensure that its material will not chemically react with this substance to maintain the stability of the substance.
Third, 28 (Alphas) - 2,4-diene - α - methyl styrene ketone has a certain degree of volatility, and the volatile gas may be irritating. The storage warehouse should be well ventilated to reduce the concentration of volatile gases in the air to avoid damage to human health. During transportation, it is also necessary to ensure that the means of transportation are well ventilated, and the container containing this substance must be tightly sealed to prevent volatile leakage.
Fourth, the handling process needs to be extra careful. This substance may be damaged in bumps, collisions, or packaging, resulting in leakage. Therefore, the handling personnel should be professionally trained, familiar with the operation specifications, handle it with care when handling, and strictly prohibit touching or dragging to ensure the safety of the transportation and storage process.

(Alfa) 2,4-diene - α - methylstyrene ketone, which has a significant impact on the environment and human health.
This substance may have complex effects in the environment. If it escapes from nature, it may migrate with water flow and airflow, and then spread in different regions. It can be adsorbed and accumulated in soil and water, affecting soil fertility and water ecology. Microbial communities in soil may change as a result, causing imbalances in soil ecosystems. In water bodies, it may endanger aquatic organisms, such as fish, shellfish, etc., disrupting their normal growth and reproduction, and damaging biodiversity.
As for human health, it should not be underestimated. If people ingest this product through breathing, diet or skin contact, it may cause many health problems. In the respiratory system, or cause airway irritation, make people cough, asthma, long-term exposure, or increase the risk of respiratory diseases. Entering the digestive system, or damaging the intestinal and gastric mucosa, causing abdominal pain, diarrhea and other diseases. And this product may be potentially carcinogenic. Long-term exposure may increase the chance of cancer and endanger life.
The ancients said: "The scourge of husband often accumulates in the small, but Zhiyong is mostly trapped in drowning." Although 2,4-diene - α - methylstyrene may seem small at first, its harm to the environment and human health should not be ignored. It is necessary to use scientific methods, rigorous monitoring, and proper prevention and control to ensure the tranquility of the environment and the health of the human body.
