To make 2-cyanogen-5-bromobenzylacetic acid ester, you can follow the following ancient method:
Take an appropriate amount of benzylacetic acid first and place it in a clean kettle. The kettle should be fired with clay, which is acid and alkali resistant and evenly heated. With a slight fire, the benzylacetic acid is slightly melted, and the shape is like clear oil.
Take another bromine, which is highly corrosive and needs to be handled with caution. Use a glass dropper to slowly drop into the benzylacetic acid in the kettle. When dripping, shake the kettle body gently to make the two even. At this time, the kettle gradually changes, the color turns slightly yellow, and there is light smoke rising, which is a sign of reaction.
After the bromine has dripped, the fire is slightly more intense. Keep the temperature in the kettle between fifty and sixty degrees, and do not make it too intense. During this period, bamboo slices need to be stirred from time to time. For about an hour (two hours), it can be seen that the liquid in the kettle turns orange yellow in color and smells a special gas. This brominated benzylacetic acid has been formed.
Then, the potassium cyanide is ground into a fine powder, and a silk sieve is used to make the particles uniform. Slowly pour into the kettle and mix with brominated benzylacetic acid. Potassium cyanide is highly toxic. When operating, when in a well-ventilated place, wear protective equipment.
Add it to the end and cover the mouth of the kettle with a damp cloth, leaving a gap for ventilation. Then the temperature was kept warm, and the temperature was controlled at about 40 degrees for about two hours (four hours). During this time, the reaction in the kettle was intense, and bubbles escaped from time to time. When the bubbles became thinner, the reaction came to an end.
Then, pour the product in the kettle into a wooden basin filled with water, and stir it with a wooden spoon. It can be seen that the oil floats on the water surface, which is the crude product of 2-cyano- 5-bromobenzylacetate. Take the bamboo Shao Kei and wash it with water several times until the water is clear and free of variegation.
Finally, place the crude product in a sand plate and bake it over a slight fire to remove its moisture. When baking, turn it over from time to time to prevent it from being burnt. When the water is gone, the pure 2-cyanogen-5-bromobenzylacetate is obtained, and the color is light yellow and crystal clear.

Precautions for the storage of 2-%-5-ethylfurfural
2-%-5-ethylfurfural. It is necessary to pay more attention to the storage and storage of this material to ensure its stability and safe operation.
In terms of storage, the first priority is the dryness of the environment. In the tidal environment, it is easy to cause the water to react and change its chemical properties. Therefore, it is appropriate to use the room where the dryness is connected, and the water source and the tidal area should be avoided. The degree is also low, and the control is appropriate. Generally, it is best to avoid high temperature. Because high temperature promotes its decomposition or accelerates the reaction, the product is not affected. The storage container should be well sealed to prevent the intrusion of oxygen and water vapor in the air.
In this case, the environment needs to be cleaned and dried, and other chemical substances need to be retained to avoid adverse reactions. And on the way, we try our best to maintain stability and avoid strong shocks and collisions. This is because it is affected by the action of strong external force, or the partial transformation of the environment, which affects the product. In addition, the degree and temperature of the environment need to be closely controlled. If the environment is biased, it is appropriate to clean and clean.
In addition, if there is no storage or loss, we must abide by the phase chemical product management regulations. Workers are familiar with the characteristics, hazards and emergency management methods of 2-%-5-ethylfurfural to ensure the safety of the whole process, prevent accidents, and ensure the safety of people and the environment from pollution.

2-% cyanogen-5-fluorouracil ethyl ester has effects on the environment and human body.
In terms of the environment, if this substance is released into nature, it has certain chemical activities and may interfere with the ecosystem. In aquatic ecology, it may affect the survival and reproduction of aquatic organisms. If plankton are sensitive to it, the concentration is slightly higher, or the number of plankton may decrease sharply, and plankton is the bottom layer of the aquatic food chain, and its changes will be transmitted layer by layer, affecting fish and other organisms. In soil ecology, it may change the structure and function of soil microbial community, interfere with soil nutrient cycling and decomposition of organic matter, and in the long run, it may cause changes in soil fertility and affect vegetation growth.
As for the human body, 2% cyanogen-5-fluorouracil ethyl ester can be harmful to health if it enters the human body through respiration, skin contact or accidental ingestion. It may be cytotoxic and interfere with the normal metabolism and division of human cells. In the body, it may inhibit DNA and RNA synthesis. Because cell division and genetic information transmission depend on this, it can lead to the inhibition of normal cell growth, especially cells that divide vigorously, such as bone marrow cells and digestive tract mucosal cells. Affected bone marrow cells can cause abnormal hematopoietic function, making people prone to anemia, infection and reduced immunity. Damage to the mucosal cells of the digestive tract can cause nausea, vomiting, diarrhea and other gastrointestinal discomfort symptoms. In addition, long-term exposure may pose a potential carcinogenic risk, due to interference with cell metabolism and genetic material, or cell carcinogenesis.
Therefore, for 2-% cyanogen-5-fluorouracil ethyl ester, caution is required, and strict regulations should be followed in the production, use and disposal to prevent it from causing adverse effects on the environment and human body.
