The chemical properties of 1% 2C4-diphenyloctadecanone are quite stable. In this compound, the diphenyl structure endows it with a certain steric barrier and electronic effect, which adjusts the intermolecular force. The existence of its long-chain alkyl group enhances the intermolecular van der Waals force, makes the molecular arrangement more orderly, and improves the stability of the substance.
Furthermore, the chemical bond energy of the substance also contributes to its stability. Covalent bonds such as carbon-carbon bonds and carbon-hydrogen bonds have higher bond energy, and more energy is required to break them. Under normal conditions, external energy cannot exceed this energy barrier, so chemical reactions are not easy to occur.
In addition, the conjugated system of aromatic rings also adds to the stability. The conjugated system can make the distribution of electron clouds more even, reduce the energy of molecules, and enhance the stability of substances. In this way, under common temperature, humidity and general chemical environments, 1% 2C4-diphenyloctadecanone can maintain the stability of its chemical structure, and few spontaneous chemical changes occur. However, under special conditions, such as high temperature, strong oxidants or the action of specific catalysts, its stability may be destroyed, triggering corresponding chemical reactions. But overall, under normal conditions, the chemical properties of 1% 2C4-diphenyloctadecanone are stable.

The method for preparing 1% 2C4-dibromooctahydromethylene naphthalene is to take methylene naphthalene and react with bromide. The method is as follows:
First put methylene naphthalene in a suitable reactor, which needs to be clean and dry to prevent impurities from disturbing it. After slowly injecting bromine, the rate should be controlled and the reaction should not be overly dramatic. And it needs to be done in a low temperature environment, because high temperature is prone to side reactions.
When reacting, it is advisable to keep stirring to make the two fully contact and promote the speed of the reaction. Use a magnet stirrer or a mechanical mixer to make sure to stir well and stop.
After the bromine injection is completed, the reaction is maintained for a period of time. During this period, close observation is required to control the temperature and time depending on the reaction process. The degree of reaction can be measured by thin-layer chromatography or other suitable analytical means.
After the reaction is completed, the product is extracted with an appropriate solvent, usually an organic solvent such as dichloromethane and ether. After extraction, the water content is removed with a desiccant such as anhydrous sodium sulfate to obtain a crude product.
After distillation, recrystallization and other methods are used to refine the crude product to obtain a high purity of 1% 2C4-dibromooctahydromethylene naphthalene. During distillation, it is necessary to control the temperature and pressure to make the product pure; for recrystallization, a suitable solvent is selected to make the product crystallize and precipitate for the purpose of purification. In this way, 1% 2C4-dibromooctahydromethylene naphthalene can be prepared.

1% 2C4-diphenyloctadecane should pay attention to the following things during storage and transportation:
First, in terms of storage, it should be found in a cool and dry place. This is because 1% 2C4-diphenyloctadecane is afraid of moisture, and the humid environment may cause it to deteriorate, which affects the quality. In the warehouse, the temperature should be stable and should not fluctuate widely to prevent physical or chemical changes due to temperature changes. And it must be stored in isolation from oxidants, acids, etc. 1% 2C4-diphenyloctadecane has relatively active chemical properties. If it is mixed with the above items, or reacts chemically, it will cause danger. Furthermore, the storage place should be well ventilated to prevent the accumulation of volatile gases and reduce safety hazards. It is also necessary to regularly inspect the packaging to see if it is damaged or leaking. If so, it should be dealt with in time.
Second, in terms of transportation, ensure that the packaging is tight and firm. Bumps in transit are inevitable, and poor packaging is prone to leakage. It is also crucial to choose suitable transportation tools. Do not transport the same car with contraindicated items. When driving, the driver should drive at a steady speed to avoid violent operations such as sudden brakes and sharp turns to reduce the possibility of collision and friction. At the same time, transport personnel must be familiar with the characteristics of 1% 2C4-diphenyloctadecane and emergency treatment methods. In case of emergencies such as leakage, they can respond in time to minimize harm. Transportation vehicles should also be equipped with corresponding fire equipment and leakage emergency treatment equipment to prepare for emergencies.
