4-Iodine-3-nitrotoluene, with a content of 97%, the market price is difficult to determine. The price of easy market access often changes due to various reasons. The regions where it is produced vary, and the price may vary. If it is near the source of production, the cost of commercial transportation is saved, and the price may be slightly lower; if it is far away, the cost of transshipment will increase, and the price may be high.
And the supply and demand of the city is also the key. If there are many seekers and there are few suppliers, the price will increase; if the supply exceeds the demand, the merchant will sell his goods quickly, and the price may drop.
In addition, the quality of coarse is also tied to the price. Although the content of cloud is 97%, it may be mixed with others. If you carefully check its quality, the price of the high-quality one will be higher than that of the low-quality one.
In addition to the differences in business establishments, the price is also different.

Furthermore, the price of 4-iodine-3-nitrotoluene may fluctuate with the flow of time.
Therefore, in order to determine its price, it is necessary to carefully examine the origin, supply and demand, quality, and timely transportation of the business establishment in order to have a more accurate number.

4-Iodine-3-nitrotoluene, with a content of 97%, the production process is as follows:
The starting material is often toluene. The first step is the nitrification reaction, with a mixed acid composed of concentrated nitric acid and concentrated sulfuric acid as the nitrification reagent. The two are carefully prepared in a certain proportion, toluene is slowly added to it, and the reaction temperature needs to be strictly controlled in a specific range, such as the low temperature range, generally 0-10 ° C. The reason for this operation is that the nitrification reaction is violent and exothermic, and low temperature can effectively control the reaction rate, avoid excessive nitrification and other side reactions, and ensure that the main generation of 3-nitrotoluene. In this reaction process, nitric acid in the mixed acid is catalyzed by sulfuric acid to produce nitroyl positive ions (NO ²), which attack the toluene ring as an electrophilic reagent. Because methyl is an ortho-para-localization group and the density of the meta-site electron cloud is relatively low, nitroyl positive ions preferentially attack the methyl meta-site, resulting in 3-nitrotoluene.
The second step is the iodization reaction. 3-nitrotoluene is put into the reaction system, and the iodine elemental substance is used as the iodizing reagent. Usually, catalysts such as potassium iodide and other cocatalysts need to be added. Potassium iodide can interact with iodine elemental substance to generate iodine tri-ion (I 🥰), which enhances the nucleophilicity of iod The reaction solvents are mostly polar organic solvents, such as acetonitrile, to facilitate uniform dispersion of the reactants and full contact. The temperature control of the reaction is also critical, and it is often carried out under mild heating conditions, usually 50-80 ° C. Under the action of this temperature and catalyst, iodine atoms replace methyl ortho-hydrogen atoms in 3-nitrotoluene to generate 4-iodine-3-nitrotoluene.
After the reaction is completed, the separation and purification of the product is also critical. After the extraction operation, the organic phase is extracted from the reaction mixture with a suitable organic solvent, such as dichloromethane. The organic phase is then washed with water to remove residual acids and water-soluble impurities. The organic phase is then dried with a desiccant such as anhydrous sodium sulfate to remove trace moisture. Finally, the high purity product of 4-iodine-3-nitrotoluene was obtained by vacuum distillation according to the boiling point characteristic of 4-iodine-3-nitrotoluene.

4-Iodine-3-nitrotoluene, with a content of 97%, has many Quality Standards. First purity, this is the key. 97% purity indicates that the content of the main component is quite high, but there are still 3% impurities. The type and content of impurities need to be carefully investigated, because it may affect the performance and use of the product.
In terms of appearance, it usually shows a specific color and form, or is crystal, or powder, color or light yellow, or nearly colorless. It needs to be uniform and consistent, and there is no visible foreign matter, otherwise it may imply poor quality.
Physical properties such as melting point and boiling point are also important standards. Precise melting point can determine the purity and characteristics of the substance, deviate from the normal range, or change the melting point due to impurities. The boiling point is the same, which can reflect the purity and stability of the substance.
Stable chemical properties are also important. Under conventional storage and use conditions, it is not easy to react with substances in the environment, otherwise it will affect the life of the product and the application effect.
For impurities, not only the total amount is concerned, but also the composition is clear. Different categories of impurities such as metal impurities and organic impurities have different effects on the product. Some metal impurities may catalyze specific reactions and change the properties of the product; organic impurities may affect the purity and reactivity of the product.
In addition, solubility is also considered. There is a suitable solubility in specific solvents to meet different application scenarios. For example, it is well dissolved in organic solvents to facilitate participation in organic synthesis reactions.
These are the common Quality Standards for 4-iodine-3-nitrotoluene 97% purity products, which must be strictly followed by production, inspection and users to ensure product quality and application effect.

4-Iodine-3-nitrotoluene, with a content of 97%, many matters need to be paid attention to during storage and transportation.
This chemical is dangerous. When storing, a cool and ventilated warehouse should be selected. Due to the danger caused by heat, it should be kept away from fire and heat sources. The temperature of the warehouse should not be too high to prevent its properties from changing or causing safety accidents. At the same time, it should be stored separately from oxidants and edible chemicals, and must not be mixed. Otherwise, it may cause severe chemical reactions and endanger safety. The storage area should be equipped with suitable materials to contain leaks, in case of leakage, it can be properly handled in time to avoid the spread of hazards.
During transportation, it is necessary to ensure that the container does not leak, collapse, fall or damage. During transportation, it should be protected from exposure to the sun, rain and high temperature. The trough (tank) car used during transportation should have a grounding chain, and holes can be set in the trough to baffle to reduce shock and generate static electricity. Mixing with oxidants and edible chemicals is strictly prohibited. During transportation, it should be driven according to the specified route, and do not stop in residential areas and densely populated areas to reduce latent risk to the public. Loading and unloading personnel should wear appropriate protective equipment when operating to avoid direct contact with the chemical, and the loading and unloading process should also be cautious to prevent packaging damage. In this way, the safety of storage and transportation should be guaranteed.
