Its physical properties are particularly important. At room temperature, it is often in the shape of a solid state, mostly white or off-white powder, with a delicate appearance and a unique feel. The number of its melting point is quite critical. Because the melting point can be determined at the beginning of its heating change, the melting point of this compound is quite high, and a specific temperature range is required to melt. This must be carefully considered when processing and applying. In addition, its solubility is also a physical property item. In common organic solvents, such as some aromatic hydrocarbons and halogenated hydrocarbon solvents, it has a certain solubility. However, in solvents with strong polarity such as water, the solubility is extremely small and almost insoluble. This property is related to the polarity of the molecular structure.
As for chemical properties, 2% 2C7-difluoro-3% 2C6-naphthalic acid dianhydride is very active. Due to the structure of difluoro groups and acid anhydrides in the molecule, it has unique reactivity.

What is the preparation method of 2,7-dihydroxy-3,6-naphthalene disulfonate disodium salt?

To prepare 2,7-dimethyl-3,6-dimethylnaphthalic acid dianhydride, the method is as follows:
First take an appropriate amount of 2,7-dimethylnaphthalene and place it in a clean reactor. Add a specific catalyst, such as a metal salt or a composite catalyst system with high catalytic activity, and add an appropriate amount of oxidizing agent, such as air, oxygen or specific organic peroxides. Control the reaction temperature in a suitable range, generally between 150-300 degrees Celsius. This temperature range can promote the effective progress of the reaction and ensure the selectivity of the reaction. The reaction pressure also needs to be precisely adjusted to maintain a certain value, about 1-10 MPa. Under this pressure condition, the reaction rate and product generation efficiency can be optimized.
During the reaction process, the reaction process needs to be closely monitored, and the consumption of raw materials and the formation of products can be known in real time by high performance liquid chromatography, gas chromatography and other analytical methods. When the reaction reaches the expected level, that is, the conversion rate of 2,7-dimethyl-naphthalene reaches a high level and the amount of 2,7-dimethyl-3,6-naphthalic acid is considerable, the reaction is terminated.
Then, the mixture obtained by the reaction is separated and purified. First, the target product is extracted with a suitable solvent, and the target product is transferred to a specific solvent phase, which is initially separated from the by-products and unreacted raw materials. Then the extracted phase is distilled to remove the solvent and low-boiling impurities according to the difference in the boiling points of each component. Finally, through further purification by means of recrystallization, a suitable solvent is selected, and the cooling rate and crystallization time are controlled to obtain high-purity 2,7-dimethyl-3,6-naphthalic acid.
The purified 2,7-dimethyl-3,6-naphthalic acid is placed in another reaction vessel, and an appropriate amount of dehydrating agent, such as acetic anhydride or phosphorus pentoxide, is added. The dehydration reaction is carried out at an appropriate temperature of about 100-200 degrees Celsius. After the reaction for a period of time, 2,7-dimethyl-3,6-naphthalic acid dianhydride is obtained. After subsequent refining treatment, the target product that meets the quality requirements can be obtained.
