1%2C2-%5B%28Difluoromethylene%29Dioxy%5DBenzene, that is, 1,2- (difluoromethylene) dioxy benzene, this material is unique, colorless and transparent liquid, with a specific odor. Its melting point is related to the intermolecular force, and the melting point is low. It is liquid at room temperature, with a moderate boiling point, about 170-180 ° C. Due to the molecular structure containing benzene ring and difluoromethylene dioxy group, the intermolecular force changes.
Its solubility is soluble in common organic solvents, such as ether, chloroform, etc. Because its molecules have a certain polarity, it can form intermolecular forces with organic solvents. It has good solubility in polar solvents, but poor solubility in water. Because water is a strong polar solvent, it does not match the intermolecular forces of this substance. The density of
is slightly higher than that of water, about 1.3-1.4g/cm ³, which is determined by its molecular composition and structure. The atomic weight of the benzene ring and the difluoromethylene dioxy group is large, resulting in large molecular mass and tight spatial arrangement.
In terms of stability, the substance is stable under general conditions, and can react at high temperatures and strong oxidants. Although the benzene ring is stable, the fluorine atoms in the difluoromethylene dioxy group have strong electronegativity, which changes the density of the electron cloud in some parts of the molecule, and can participate in the reaction under specific conditions. And it has a certain volatility and can evaporate slowly in the air. Pay attention when using and storing.

1%2C2-%5B%28Difluoromethylene%29Dioxy%5DBenzene, the Chinese name is or 1,2- [ (difluoromethylene) dioxy] benzene. This substance has unique chemical properties.
From the structural point of view, the two oxygen atoms on the benzene ring are connected by difluoromethylene, and the fluorine atoms are highly electronegative, causing uneven distribution of electron clouds, so that the substance may have a certain polarity. This polarity affects its solubility, and its solubility in polar solvents is better than that in non-polar solvents.
Because of the benzene ring, it has aromaticity and high stability, and is not easy to undergo addition reactions like olefins. However, electrophilic substitution reactions can occur under specific conditions, such as halogenation, nitrification, sulfonation, etc. Spatial resistance of ortho-two substituents in the benzene ring may affect the reactivity and selectivity.
The fluorine atom of the difluoromethylene part has high electronegativity and high C-F bond energy, which enhances the chemical stability and thermal stability of the substance. At the same time, the vibration absorption peak of the C-F bond is unique, which is an important identification basis in infrared spectroscopy.
In addition, this substance may have certain biological activity. In the field of pharmaceutical chemistry, fluorinated organic compounds can change the lipophilicity, metabolic stability and biological activity of compounds due to the special properties of fluorine atoms, so 1,2- [ (difluoromethylene) dioxy] benzene may have potential application value in drug development.

1%2C2-%5B%28Difluoromethylene%29Dioxy%5DBenzene, that is, 1,2 - (difluoromethylene) dioxy benzene, the preparation method is as follows:
To obtain this compound, catechol is often used as the starting material. Catechol has a benzene ring structure with two adjacent hydroxyl groups. Catechol is reacted with dichloromethane under specific conditions. This reaction requires a suitable solvent, such as some non-protic organic solvents, to facilitate the reaction.
During the reaction process, the reaction temperature and pressure need to be strictly controlled. Too high or too low temperature may affect the rate of reaction and the purity of the product. Pressure is also a key factor, and appropriate pressure can promote effective collision between reactants and improve the reaction efficiency. The catalyst used in the

When the reaction is over, the product needs to go through a series of separation and purification steps. First, the product is separated from the unreacted raw materials and by-products by distillation according to the difference in the boiling points of each component. Then it is further purified by column chromatography and other means to obtain high-purity 1,2 - (difluoromethylene) dioxy benzene.
During operation, due to the involvement of certain toxic and volatile substances such as difluorochloromethane, it is necessary to carry out in a well-ventilated environment, and the operator should take appropriate protective measures to ensure safety.

1% 2C2 - [ (Difluoromethylene) Dioxy] Benzene, that is, 1,2 - (difluoromethylene dioxy) benzene, there are many things to pay attention to during use.
