Under normal conditions, or in the form of a colorless to yellowish liquid, it is quite fluid. Its smell, or elegant and unique fragrance, although not strong and pungent, but you can detect its unique smell when you smell it.
As for the boiling point, due to the interaction of special oxygen heterocycles in the molecular structure with vinyl groups, its boiling point is within a specific range. Roughly speaking, its boiling point will be within a certain temperature range, and the establishment of this temperature range depends on the magnitude of the intermolecular forces. The polarity imparted by the heterocycle of oxygen and the unsaturated properties of vinyl all affect the intermolecular forces, which in turn determine its boiling point.
Melting point is also influenced by molecular structure factors. Due to the particularity of its structure, the molecular arrangement shows a specific law, so the melting point also has a corresponding value. Intermolecular van der Waals forces and possible hydrogen bonds interact to shape the characteristics of its melting point.
Solubility is also one of its important physical properties. In organic solvents, such as common ethanol, ether, etc., 1% 2C3-dioxy-4-vinylfuran may exhibit good solubility. Due to the fact that the polarity of the organic solvent and the polarity of the compound have a certain degree of matching, the principle of similar miscibility is revealed. In water, because the polarity of the molecule is not completely compatible with the polarity of water, the solubility may be poor.
In addition, the density of the compound cannot be ignored. Its density may be slightly different from that of common organic liquids. This difference is due to the relative mass of the molecules and the tightness of the intermolecular packing. The compactness of the molecular structure is directly related to the size of its density. From its special structure, it can be seen that its density should be within a certain reasonable value range, which is of important reference value for metering, mixing and other operations involved in practical applications.

1% 2C3-dideuterium-4-pentenonitrile is an organic compound with unique chemical properties and a significant position in the field of organic synthesis.
In this compound, the introduction of deuterium atoms has a profound impact on its properties. Although deuterium and hydrogen are isotopes, deuterium has a higher mass, resulting in a stronger C-D bond than C-H bond and a lower vibration frequency. As a result, the stability of 1% 2C3-dideuterium-4-pentenonitrile has been improved. In some chemical reactions, the reaction rate containing C-D bond is different from that containing C-H bond, which shows a kinetic isotope effect.
The nitrile group (-CN) is a key functional group of 1% 2C3-dideuterium-4-pentenonitrile, which endows the compound with many active reactivity. The nitrile group can be hydrolyzed to form carboxyl groups (-COOH), which can occur under acidic or basic conditions. For example, in a strong base such as sodium hydroxide aqueous solution, the nitrile group is gradually hydrolyzed when heated to form amides, and then carboxylate and ammonia are formed. Carboxylic acids can be obtained after acidification.
The nitrile group can also participate in nucleophilic addition reactions.

1% 2C3-dideuterium-4-pentenonitrile has broad application prospects in the fields of medicinal chemistry, materials science and other fields due to its unique chemical properties. It can be used as a key intermediate for the synthesis of new compounds with specific properties.

The preparation method of 1% 2C3-dibromo-4-vinylbenzene is not directly described in Tiangong Kaiwu, but it can be deduced from the ancient people's chemical process wisdom and the preparation of similar substances.
Ancient chemical processes mostly originated from practice accumulation, and were carried out with common raw materials and simple equipment. Preparation of this compound can be started from bromine-containing and vinyl-containing raw materials.
Bromine, ancient or from seawater, salt lake brine. After seawater evaporation and concentration, bromine-containing compounds can be obtained by precipitation and oxidation-reduction methods. Although the ancients did not have modern precise purification technology, through repeated crystallization and separation, relatively pure bromide can also be obtained.
Preparation of vinylbenzene, can be found in natural substances containing benzene rings and alkenyl groups, such as certain plant essential oils or special minerals. In ancient times, there were distillation and extraction methods, which can extract related ingredients from natural substances.
Preparation of 1% 2C3-dibromo-4-vinylbenzene, or first purify styrene substances by distillation and extraction of natural benzene rings. Then the extracted styrene and the extracted bromide are reacted under appropriate conditions. Although the ancients did not have the concept of modern catalysts, they may have tried to find that certain metals, ores or plant extracts can accelerate the reaction. The reaction site may be a special ceramic or metal container, and the reaction temperature is controlled by heating on a stove.
After the reaction, the product is separated, or according to its physical properties, such as boiling point, solubility, etc., the pure 1% 2C3-dibromo-4-vinylbenzene is obtained by distillation and recrystallization. Although the ancient method is difficult to achieve modern precision and efficiency, its spirit of exploration and practical wisdom have laid the foundation for the development of later chemistry.

1% 2C3-dihydro-4-alkenyl naphthalene, when hiding and transportation, need to pay attention to many matters.
When hiding, the first environment. Must choose a cool, dry and well-ventilated place. If the environment is hot, it is easy to cause its properties to mutate or cause chemical reactions. For example, if placed in a wet place, water vapor invades it, lest it decompose or deteriorate and lose its original properties. In addition, it must be far away from fire and heat sources. Many of these materials are flammable, and near fire is dangerous. If you are not careful, you will start a fire, which is not a big disaster.
When transported, protection comes first. The person handling, in front of the appropriate protective equipment, such as gloves, goggles, etc., to prevent the object from coming into contact with the skin, eyes and eyes, causing injury to the body. When loading and unloading, it must also be handled with care and should not be treated rudely. If it is thrown and collided, it will not only damage its quality, but also cause accidents. The container for transportation must be firmly sealed to prevent leakage. If it leaks outside, it will pollute the environment on the one hand, and endanger the surrounding people and animals on the other.
And during transportation, it should be controlled for temperature and vibration. If the temperature is too high, it is easy to cause its chemical properties to be unstable; if it vibrates too much, it may also cause adverse reactions. Therefore, the transportation vehicle should have a temperature-controlled device, travel on a smooth road, and move slowly to ensure the safety of 1% 2C3-dihydro-4-alkenyl naphthalene, and reach its destination smoothly.
