1% 2C2 -diphenylethanedione, also known as bibenzoyl, is an important compound in organic synthesis. Its physical and chemical properties are as follows:
- ** Physical properties **:
- ** Appearance **: Usually appears as a light yellow crystalline powder. Looking at it, the color is elegant, the texture is delicate, and it has a unique appearance under light or weak luster.
- ** Melting point **: about 95-96 ° C. When heated to this point, its solid structure begins to be destroyed, the intermolecular forces change, and the substance gradually melts from solid to liquid.
- ** Boiling point **: up to 346-348 ° C. At this temperature, the molecule obtains enough energy to break free from the liquid phase and transform into a gaseous state to escape.
- ** Solubility **: It is insoluble in water, due to the strong hydrogen bonding between water molecules, and 1% 2C2-diphenylethylene diketone is a non-polar or weakly polar molecule, which interacts weakly with water, so it is insoluble. However, it is soluble in organic solvents such as ethanol, ether, and chloroform, because these organic solvents and 1% 2C2-diphenylethylene diketone molecules can interact with van der Waals forces to achieve mutual solubility.
- ** Chemical Properties **:
- ** Carbonyl Reaction **: The molecule contains dicarbonyl, the carbonyl group is polar, and the carbon is positively charged, which is vulnerable to nucleophilic attack. If it can react with hydroxylamine to form oxime, it can react with hydrazine to form hydrazone. Taking the reaction with hydroxylamine as an example, the nitrogen atom of hydroxylamine is rich in electrons and has strong nucleophilicity, which attacks carbonyl carbon. After a series of proton transfer and dehydration steps, oxime compounds are formed. This reaction is often used in organic synthesis to identify and prepare compounds containing oxime structures.
- ** Reduction Reaction **: Can be reduced. When treated with strong reducing agents such as lithium aluminum hydride, carbonyl groups can be reduced to alcohol hydroxyl groups to obtain 1% 2C2-diphenyl-1% 2C2-ethylene glycol. This reaction is an important method for constructing the structure of diols. It is widely used in organic synthesis and can be used to prepare alcohols with special structures and functions.
- ** Oxidation Reaction **: Although relatively stable, under specific conditions, such as the action of strong oxidants, it can be further oxidized, carbonyl groups or converted into other functional groups, such as carboxyl groups. The specific oxidation products are closely related to the reaction conditions, and different oxidants and reaction conditions will cause different oxidation pathways and products.

1% 2C2-diphenylethanedione, commonly known as bibenzoyl, its preparation process was not as fine as modern science in ancient times, but there are methods to follow. According to the idea of "Tiangong Kaiwu", it can be described from the aspects of raw material selection and treatment, reaction process, product separation, etc.
First talk about the raw material, prepare 1% 2C2-diphenylethanedione, the commonly used raw material is benzaldehyde. In ancient times, or extracted from natural benzaldehyde-containing plants. Such as some flowers and spice plants, crude benzaldehyde is obtained by simple means such as distillation and extraction. After obtaining benzaldehyde, it needs to be further refined to improve the purity before it can be used in subsequent reactions.
The reaction process is quite critical. According to the theory of chemical knowledge, benzaldehyde can be oxidized to obtain 1% 2C2-diphenylethanedione under specific conditions. Although there were no modern advanced catalysts and reaction equipment in ancient times, natural oxidants, such as oxygen in the air, were used to promote the reaction in an alkaline environment. Refined benzaldehyde can be placed in an open container, and an appropriate amount of alkaline substances, such as plant ash (containing alkaline components such as potassium carbonate), can be added to make benzaldehyde slowly oxidize at room temperature or slightly hot conditions. This process requires patience, because the reaction rate is slow, and it needs to be stirred frequently to make the reactants fully contact and accelerate the reaction.
Product separation is also an important link. After the reaction is completed, the mixture contains 1% 2C2-diphenylethanedione and unreacted raw materials and by-products. In ancient times or using the difference in solubility of substances to separate. The solubility of 1% 2C2-diphenylethylenedione varies in some organic solvents. Appropriate solvents, such as ethanol, ether, etc., can be selected to dissolve the reaction mixture. 1% 2C2-diphenylenedione dissolves in the solvent, while impurities are precipitated or insoluble, and impurities are filtered to remove impurities. After that, the solution containing the product is distilled to evaporate the solvent, leaving a purer 1% 2C2-diphenylenedione. However, this process also needs to be handled carefully, and the distillation temperature and time should be controlled to prevent the decomposition or loss of the product.

1% 2C2-diphenylethylene diketone is an important intermediate in organic synthesis. Safety issues are of paramount importance during use. The following are some points to be noted:
First, it is related to toxicity and health effects. 1% 2C2-diphenylethylene diketone has certain toxicity. It is necessary to avoid inhaling its dust during operation, and to prevent contact between the skin and the eyes. If inhaled inadvertently, it may cause respiratory irritation, causing cough, asthma, etc.; if it comes into contact with the skin, it may cause skin allergies, itching, redness and swelling; if it splashes into the eyes, it may cause serious irritation and damage to the eyes. When operating, wear suitable protective equipment, such as protective glasses, gloves and masks. After the operation, wash the contact area with soap and water in time.
Second, it is about the risk of combustion and explosion. This substance is flammable and is dangerous to burn when heated or exposed to open flames. Therefore, storage and use should be kept away from fire and heat sources, and well ventilated to prevent the formation of explosive mixtures of combustible dust and air. At the same time, avoid storage or mixed use with strong oxidants, which may cause violent chemical reactions and even cause explosions.
Third, in terms of storage. Store 1% 2C2-diphenylethylene dione in a cool, dry and well-ventilated place away from incompatible substances. It should be sealed to prevent moisture and deterioration. Periodic inspection of the storage area should be carried out to check for leaks or other safety hazards.
Fourth, pay attention to the main points of operation. When performing operations involving 1% 2C2-diphenylethylenedione, it should be carried out in an environment with good ventilation conditions, such as a fume hood, to reduce the concentration of toxic dust in the air. The operation process should be cautious to prevent it from being scattered or flying due to collision, friction, etc. In the event of a leak, unrelated personnel should be evacuated quickly, and the leakage area should be isolated. Emergency personnel should wear protective equipment and use appropriate methods to collect and clean up the leak, so as not to spread it.
