The preparation method of 1% 2C2-diphenylethanedione, also known as bibenzoyl, is not directly described in "Tiangong Kaiwu", but according to the ancient chemical process principle and modern chemical knowledge, it can be made as follows.
To prepare 1% 2C2-diphenylethanedione, benzoin is often used as the starting material. Benzoin can be prepared by benzaldehyde condensation reaction catalyzed by potassium cyanide (or vitamin B1). In this reaction, benzaldehyde molecules are combined with each other under the action of a specific catalyst to form benzoin, which is like the merger of the two substances and coagulates into one.
After benzoin is obtained, it can be oxidized to prepare 1% 2C2-diphenylethanedione. In the past, mild oxidizing agents such as nitric acid were commonly used. Benzoin and nitric acid were co-placed in a suitable container and heated moderately. Nitric acid has strong oxidizing properties and can capture hydrogen atoms at specific locations in benzoin molecules and convert them into carbonyl groups, thereby forming 1% 2C2 -diphenylethanedione. During the reaction, the color state of the solution can be seen gradually changing, and the smell is also different, which are all characteristics of the reaction.
However, nitric acid is corrosive and harmful gases such as nitrogen oxides are generated during the reaction, which does not conform to the ancient green process concept and is also dangerous. Therefore, there is also a method of using copper acetate as an oxidizing agent. Copper acetate reacts with benzoin under alkaline conditions, the copper ions are reduced from divalent to monovalent, and benzoin is oxidized to 1% 2C2-diphenylethanedione. After the reaction, through cooling, crystallization, filtration, washing and other operations, a relatively pure product can be obtained.
The preparation process requires careful observation of the temperature and time of the reaction, and the proportion of the material. If the temperature is too high, the product may decompose; if the time is too short, the reaction will not be completed; if the proportion of the material is improper, it will also affect the yield. When operating, it is necessary to follow the ancient caution and the modern science to achieve the best effect.

1% 2C2-dibenzylketoxime is a highly toxic chemical. When storing and transporting, it is necessary to be cautious and take many precautions not to be ignored.
First storage environment. A cool and ventilated warehouse must be selected, away from fire and heat sources. It is easy to decompose due to heat, and even cause dangerous reactions. The temperature of the warehouse should not be higher than 30 ° C, and the relative humidity should be maintained below 80%. This product should be stored separately from oxidants, acids and bases, and should not be mixed. Because of its contact with these substances, violent chemical reactions may occur, resulting in explosion, combustion and other serious consequences. And the warehouse should be equipped with suitable materials to contain leaks in case of leakage, which can be properly handled in time.
When transporting, the same cannot be slack. Before transportation, make sure that the packaging is complete and the loading is safe. The packaging should meet relevant standards to prevent material leakage due to damage during transportation. The transportation process should strictly follow the specified route, and do not stop in densely populated areas and open flames. The transportation vehicle should be equipped with the corresponding variety and quantity of fire fighting equipment and leakage emergency treatment equipment. The escort personnel must also be familiar with the characteristics of the transported items and emergency disposal methods, and carefully guard all the way to ensure the safety of transportation.
In short, the storage and transportation of 1% 2C2-dibenzylketoxime is related to the safety of personnel and the environment. Any details should not be underestimated. It is necessary to operate with a high degree of responsibility and strict compliance with regulations to ensure the safety of the whole process.

1% 2C2-diphenylethylhydrazide is an organic compound with a lot of relevant safety information. Let me tell you one by one.
Its properties are usually white to light brown crystalline powder, odorless and slightly bitter in taste. It is quite stable at room temperature and pressure.
However, this product also has certain safety precautions when using and storing. In terms of toxicity, although it is not a highly toxic product, it should not be contacted or ingested at will. If it comes into contact with the skin accidentally, it should be rinsed with plenty of water immediately; if it enters the eyes, it should be rinsed quickly with flowing water or normal saline, and seek medical attention in time.
In terms of explosion, this compound is flammable. In case of open flame, hot topic or contact with oxidant, there is a risk of combustion and explosion. Therefore, in storage and use places, fireworks should be strictly prohibited, and away from fire sources, heat sources and strong oxidants. When storing, it should be placed in a cool and ventilated warehouse, sealed to prevent moisture and deterioration.
During transportation, it should also be properly packaged in accordance with relevant regulations to avoid severe vibration and collision, so as to prevent leakage due to package damage.
During operation, it is recommended that operators wear appropriate protective equipment, such as protective glasses, gloves and protective clothing, to reduce the risk of exposure. At the same time, the workplace should have good ventilation conditions to prevent dust accumulation.
All of this safety information needs to be taken into account in activities involving 1% 2C2-diphenylacetylhydrazide to ensure the safety of personnel and the environment.
