To prepare 4-allyl-1,2-diacetate glyceryl ester, you can follow the following ancient method.
First take glycerol as the group, because of its trihydroxyl group, the activity is quite good. Under appropriate reaction conditions, glycerol and acetic anhydride meet. When the two meet, the acyl group of acetic anhydride will interact with the hydroxyl group of glycerol.
In the reactor, adjust the temperature to a moderate temperature, about fifty to sixty degrees Celsius. The environment in the kettle should be kept dry to prevent impurities from disturbing it. With an appropriate amount of sulfuric acid as the catalyst, sulfuric acid can promote the reaction rate, but the amount should not be too much, and too much will easily cause side reactions.
During the reaction, fine bubbles can be seen escaping in the kettle, which is a sign of the reaction going on. After several hours of reaction, the two hydroxy groups of glycerol combine with the acyl group of acetic anhydride to form 1,2-diacetate glyceride.
Then, to add allyl to it. Take an allyl halide, such as allyl bromide, and place it in another reaction vessel with the 1,2-diacetate glyceride prepared before. Then introduce a base, such as potassium carbonate, which can grab the halogen atom of the allyl halide, free the allyl positive ion, and then combine with the remaining active check point of the hydroxyl group of the 1,2-diacetate glyceride.
In this step of the reaction, the temperature should be controlled at 60 to 70 degrees Celsius. During the reaction, it is necessary to continuously stir to make the reactants fully contact. After several hours of reaction, the allyl is successfully connected to the 1,2-diacetate glyceride, and the final 4-allyl-1,2-diacetate glyceride is obtained.
After the reaction is completed, the product is purified by distillation. Using the difference between the boiling points of the product and the impurities, the product is separated from the mixed system to obtain a pure 4-allyl-1,2-diacetate glyceride.

4-Bromonaphthalene-1,2-diformic anhydride is an important compound in organic chemistry. During storage and transportation, many points need to be paid attention to.
When storing, the first environment is dry. Because of its certain water absorption, if the storage environment is humid, it is easy to be hydrolyzed by moisture, resulting in quality deterioration. Therefore, it should be placed in a dry, well-ventilated place, and the humidity should be controlled at a low level.
Temperature is also critical. This compound is quite sensitive to temperature, and high temperature can easily cause it to decompose or undergo other chemical reactions. Usually, it should be stored in a cool place, and the temperature should not exceed 25 ° C.
Furthermore, it should be kept away from fire sources and oxidants. 4-Bromonaphthalene-1,2-diformic anhydride is flammable. In case of open flame, hot topic or contact with oxidant, there is a risk of combustion and explosion.
When transporting, the packaging must be stable. Appropriate packaging materials should be selected, such as sturdy plastic drums or iron drums, and filled with appropriate cushioning materials to prevent package damage caused by collision and vibration during transportation.
The choice of transportation should not be underestimated. It is necessary to ensure that the transportation vehicle is clean, dry, and free of other substances that may react with it. At the same time, the transportation process should avoid sun exposure, rain exposure, and travel routes should avoid densely populated areas and fire sources.
In addition, transportation personnel should be familiar with the characteristics of this compound and emergency treatment methods. In the event of leakage and other accidents, it can be disposed of in time and properly to avoid serious consequences. In short, the storage and transportation of 4-bromonaphthalene-1,2-diformic anhydride requires careful operation in all aspects to ensure its safety and stability.
