The fluorescent materials may have important applications in the field of optoelectronics.
3,4,5,6-tetrafluoro-phthalic acid, because of the fluorine atoms in its molecules, gives unique properties. On the one hand, in the preparation of fluorine-containing polymer materials, it is an important monomer. The introduction of fluorine atoms can significantly improve the weather resistance, chemical corrosion resistance and low surface energy of polymer materials, and the prepared fluoropolymers are often used in high-end coatings, special plastics and other fields. On the other hand, in the field of medicinal chemistry, as an intermediate with unique structure, or participate in the synthesis of drug molecules with special biological activities. Because of the special electronic effects and space effects of fluorine atoms, or change the pharmacological activity and metabolic properties of drug molecules.
In summary, 1,2-naphthalic acid and 3,4,5,6-tetrafluoro-phthalic acid play a key role in many fields such as materials science, organic synthesis, and drug development, promoting the development of chemical, materials, and pharmaceutical industries.

1%2C2-%E8%8B%AF%E4%BA%8C%E8%83%BA, that is, 1,2-naphthalic acid, 3,4,5,6-tetrafluoro-benzene has the following physical properties:
1,2-naphthalic acid, its properties are usually white to slightly yellow powder or crystal. The melting point is quite high, about 210-215 ° C. It has very little solubility in water and is almost insoluble, due to the lack of groups in its molecular structure that form effective hydrogen bonds with water, and the molecule has a large non-polar part. However, it is soluble in some organic solvents, such as dimethyl sulfoxide (DMSO), N, N-dimethylformamide (DMF), etc., because the carboxyl groups in the molecule can form certain interactions with these organic solvents.
3,4,5,6-tetrafluoro-benzene, which may be a colorless and transparent liquid under normal conditions. Its boiling point is relatively low, due to weak intermolecular forces. Due to the presence of fluorine atoms on the benzene ring, its density is slightly higher than that of ordinary benzene compounds. The electronegativity of fluorine atoms is large, so that the molecule has a certain polarity, but compared with compounds containing strong polar groups (such as hydroxyl groups, carboxyl groups), the polarity is weak. It is slightly soluble in water, because water is a strong polar solvent, the interaction with the molecule of this substance is difficult to overcome the hydrogen bond between water molecules. In organic solvents, such as ether, chloroform, etc., it has better solubility because it can form van der Waals forces and other interactions with organic solvent molecules, which is conducive to dissolution.
Both have their own unique physical properties, which determine their different application directions and processing methods in the fields of chemical industry and materials.

1%2C2-%E8%8B%AF%E4%BA%8C%E8%83%BA, its color is often light yellow or nearly colorless, and it has a slightly special smell. This substance is a liquid at room temperature, with a certain volatility and a low boiling point. Its solubility is unique, it can be miscible with many organic solvents, but its solubility in water is small. Chemical properties are more active and can participate in many reactions, such as substitution reactions and addition reactions.
As for 3%2C4%2C5%2C6-%E5%9B%9B%E6%B0%9F-%E7%9A%84, its appearance is mostly colorless and transparent liquid, and its smell is also characteristic. It is stable at room temperature, and its boiling point has its own specific value. In terms of solubility, it has a high affinity with common organic solvents and has a certain solubility in water. Chemically, it can occur various reactions such as oxidation and reduction, and has a wide range of uses in the field of organic synthesis.
Both of these are common substances in organic chemistry, each with unique physical and chemical properties. In practical application, it is necessary to operate carefully and use them properly according to their characteristics to obtain the maximum benefit and ensure safety. The study of their properties is of great significance in chemical academic inquiry and industrial production.

1%2C2-%E8%8B%AF%E4%BA%8C%E8%83%BA, it is the prescription made of aconite and aconite as the main medicinal materials. Its processing method, the ancient Fang family has its own exquisite. Aconite and aconite need to choose authentic medicinal materials, first soak in water to remove its toxicity part, and then boil or steam, so that its medicinal properties are relieved and toxicity is reduced. The cook, control its temperature and duration, in order to achieve moderate processing; the steamer, also need to accurately grasp, so as to obtain the basis of 1%2C2-%E8%8B%AF%E4%BA%8C%E8%83%BA medicinal materials.
As for 3%2C4%2C5%2C6-%E5%9B%9B%E6%B0%9F-%E7%9A%84, this is also a traditional prescription. The medicinal materials used, such as Coptis chinensis, Scutellaria baicalensis, yellow cypress, rhubarb, etc., have their own rules. Coptis chinensis is mostly born in deep mountains and damp places, and it is necessary to choose those with good shape and color when picking. After harvesting, remove its impurities, or dry them in the sun, or dry them for later use. Scutellaria baicalensis is the same, choose its firmness, the method of processing, or wine, or stir-frying charcoal, the wine will lead the medicine to go up, and the stir-frying charcoal will have the effect of hemostasis. Yellow cypress, after peeling the bark, scrape off the outer coarse skin, and also be treated by sun-frying and other methods. Rhubarb, after digging, wash and slice, or use raw, or cooked, cooked with more steaming, so that the force of its diarrhea is slightly slowed down.
All medicines are accurately weighed according to the compatibility ratio of ancient recipes, and then either studied together for the end, or decocted with water. For those who study the end, they need to make the end of the medicine delicate and uniform, so as to facilitate the effect of the medicine; for those who cook, use casseroles and other utensils to control the heat, first boil the fire, and then slowly fry the fire, so that the nature and taste of the medicine are fully integrated, so that the finished product of 3%2C4%2C5%2C6-%E5%9B%9B%E6%B0%9F-%E7%9A%84 can be applied to patients and treat various diseases.

1%2C2-%E8%8B%AF%E4%BA%8C%E8%83%BA%EF%BC%8C3%2C4%2C5%2C6-%E5%9B%9B%E6%B0%9F-%E5%9C%A8%E4%BD%BF%E7%94%A8%E8%BF%87%E7%A8%8B%E4%B8%AD%E5%BD%93%E to be cautious. Although these two things are helpful, they are used improperly, and they will also cause harm.
1%2C2-%E8%8B%AF%E4%BA%8C%E8%83%BA, with a specific nature, when used, the first thing to clarify its use. If you use it rashly, do not investigate its details, for fear of accidental changes. And this thing may have an impact on the surrounding things, so when using it, you need to pay attention to the environment to avoid damage to other things. Moreover, its preservation should also be paid attention to, according to its nature Placed in a suitable place, to prevent deterioration and loss of its use, or cause danger.
As for 3%2C4%2C5%2C6-%E5%9B%9B%E6%B0%9F, its nature is different. When using it, you must know its characteristics in detail, and use it according to its nature to obtain its benefits. In different situations, choose the right product. Such as in a dry place, or need to be moisture-proof; in a humid place, or seek moisture-resistant quality. At the same time, when using these four things, follow certain laws, do not change the steps at will, so as to avoid mistakes. Disposal after use should not be ignored, and proper disposal should not only protect the net environment, but also prevent the generation of hazards.
In short, with 1%2C2-%E8%8B%AF%E4%BA%8C%E8%83%BA and 3%2C4%2C5%2C6-%E5%9B%9B%E6%B0%9F, it is necessary to be careful, understand its nature, know its law, save it, and dispose of it properly, so that it can be safe and secure, and use its function to avoid disasters.
