What are the physical properties of 6-Nitrobenzothiazole?
6-Nitrobenzothiazole is also an organic compound. It has the following physical properties:
In terms of color and taste, at room temperature, it is mostly a light yellow to light brown crystalline powder, which is visible and has quality to touch. Smell it, often with a specific smell, but its taste is not strong, but it is also different from others.
In terms of melting point, the melting point is quite high, about 126-128 degrees Celsius. At this temperature, the substance gradually melts from the solid state to the liquid state, and the arrangement of molecules tends to be disordered from order. As for the boiling point, due to the limitation of data, although the details are not known, according to its structure and the properties of similar compounds, the boiling point should also be higher. Due to the intermolecular forces, such as van der Waals forces and hydrogen bonds, it requires more energy to convert from liquid to gaseous.
In terms of solubility, it is difficult to dissolve in water, because its molecular polarity does not match the polarity of water molecules, and the polar bonds of water are difficult to overcome the force between 6-nitrobenzothiazole molecules, making it difficult to dissolve in water. However, in organic solvents, such as ethanol, ether, acetone, etc., the solubility is acceptable. The molecular structure and polarity of organic solvents are more compatible with 6-nitrobenzothiazole, and similar interactions can be formed between molecules, so that it can be better dispersed in organic solvents.
In terms of density, its density is higher than that of water, and it will sink to the bottom when placed in water. Due to the combination of the types and quantities of atoms in the molecule, the mass per unit volume is greater than that of water.
6-nitrobenzothiazole has these physical properties and is used in many fields such as chemical industry and medicine, either as a reaction raw material or as an intermediate product, all due to its unique physical and chemical properties.
What is the chemical synthesis method of 6-Nitrobenzothiazole?
6-Nitrobenzothiazole is also an organic compound. The synthesis method used to follow the following path.
First take benzothiazole as the group, and use the mixed acid of nitric acid and sulfuric acid as the nitrifying agent to carry out the nitrification reaction. In the structure of capsulbenzothiazole, nitrogen and sulfur heterocycles have a specific electron cloud distribution. Under the action of mixed acid, the nitro group can easily be selected and connected to the benzene ring to obtain 6-nitrobenzothiazole.
During operation, dissolve benzothiazole in a suitable organic solvent, such as dichloromethane, chloroform, etc., and slowly drop into the pre-prepared mixed acid while stirring at low temperature. Among them, the strong acidity and water absorption of sulfuric acid can promote the dissociation of nitric acid, increase the concentration of nitroyl positive ions, and facilitate the progress of nitrification reactions. And the reaction rate is controlled at low temperature to avoid side reactions, such as the formation of polynitroylation products.
After the drop is completed, continue to stir for a number of times, use thin-layer chromatography or other suitable analytical means to monitor the progress of the reaction. When the raw materials are exhausted, the product is generated as expected. The reaction solution is poured into ice water, and precipitation is precipitated. The obtained product is filtered and recrystallized with a suitable solvent, such as ethanol, ethyl acetate, etc., to purify the product, and then a pure 6-nitrobenzothiazole is obtained. < Br >
There are other methods, such as using raw materials containing sulfur and nitrogen, through multi-step condensation, cyclization, nitrification and other reactions, benzothiazole rings are successively constructed and nitro groups are introduced. However, all kinds of paths, or complicated steps, or harsh conditions, are less practical than the method of direct nitrification of benzothiazole.
What is the price range of 6-Nitrobenzothiazole in the market?
It is difficult to determine the price range of 6-nitrobenzothiazole in the market. The price of 6-nitrobenzothiazole is determined by many factors, such as the source of raw materials, the method of preparation, market demand and supply.
Looking at the market of chemical raw materials in the past, if the raw materials are abundant and easy to obtain, the preparation method is simple and low cost, and the market demand is small and more than available, the price is low; on the contrary, if the raw materials are rare, the preparation is difficult and the cost is high, the market demand is insufficient, and the price is high.
In the world of "Tiangong Kaiwu", although there is no such thing as 6-nitrobenzothiazole, the price of chemical raw materials is the same in ancient and modern times. If you want to explore the price of 6-nitrobenzothiazole in ancient times, you need to study its upstream and downstream industries in detail. If the raw materials are common, the preparation process is common, and the price per gram may be between a few yuan and tens of yuan; if the raw materials are rare, the preparation price may be as high as 100 yuan per gram, or even higher. But this is only an idea, and the actual price still needs to be determined by consulting chemical raw material suppliers and looking at market transaction records.
6-Nitrobenzothiazole What are the precautions during storage and transportation?
6-Nitrobenzothiazole is also a chemical substance. During storage and transportation, many matters must be paid attention to.
First, storage, because it has a certain chemical activity, should be stored in a cool, dry and well-ventilated place. Avoid open flames and hot topics to prevent them from being decomposed by heat and causing dangerous accidents. And should be stored separately from oxidants, acids, alkalis, etc., because of or with violent chemical reactions. If mixed, it may cause disasters such as combustion and explosion.
In addition, when transporting, it needs to be handled lightly, and it must not be operated brutally to prevent packaging damage. Once the packaging is damaged, 6-nitrobenzothiazole leaks, which not only pollutes the environment, but also endangers the safety of personnel. Transportation vehicles also need to be equipped with corresponding fire equipment and leakage emergency treatment equipment. In case of emergencies, they can respond in time. During transportation, ensure that the container does not leak, collapse, fall or damage.
In addition, storage and transportation sites need to be managed by professional personnel, and complete safety operating procedures and emergency plans are formulated. Relevant personnel must also undergo professional training, familiar with the nature of 6-nitrobenzothiazole and emergency treatment methods, so as to ensure the safety of storage and transportation.
