To prepare 2-cyano-3-cyano-5-trifluoromethylpyridine, the following ancient methods can be used.
First, a compound containing a pyridine structure is used as the starting material, and the method of cyanidation is used. First, an appropriate pyridine derivative is taken, and an appropriate amount of cyanide reagent, such as potassium cyanide and sodium cyanide, is added to a specific reaction vessel, and then a suitable catalyst and reaction solvent are added. This reaction needs to be carried out under precisely controlled temperature and pressure conditions. The temperature may be maintained at a certain range, and the pressure needs to be stabilized at a certain value. Only in this way can a cyanide reaction occur at a specific position on the pyridine ring to introduce cyanide groups. In this process, the type and amount of catalyst have a great influence on the reaction rate and selectivity, and need to be carefully prepared.
Second, a series of reactions can be started from fluorine-containing compounds to construct pyridine rings and introduce cyanyl groups. First, the halogenated hydrocarbons containing fluorine are reacted with reagents containing nitrogen and cyanide groups to form preliminary intermediates. This reaction may require a basic environment to promote the occurrence of nucleophilic substitution reactions. Appropriate bases, such as potassium carbonate, sodium carbonate, etc., are selected to control the reaction temperature and time, so that the halogen atoms of halogenated hydrocarbons are replaced by groups containing cyanide groups. Then, the intermediate is cyclized under suitable conditions, such as under the action of a specific acidic or basic catalyst, the functional groups in the molecule interact to form a pyridine ring, and at the same time retain or further introduce the desired cyanyl group and trifluoromethyl group.
Third, a stepwise synthesis strategy can also be adopted. First prepare the pyridine intermediate containing trifluoromethyl group, and then introduce the cyanyl group through the cyanation reaction. First synthesize the pyridine derivative containing trifluoromethyl group by a suitable method, for example, by reacting pyridine with a reagent containing trifluoromethyl group under specific conditions. Then, for the specific position of the intermediate, select the appropriate cyanide method to achieve the introduction of the cyanyl group. In this process, it is necessary to pay attention to the influence of the existing substituents on the pyridine ring on the subsequent cyanidation reaction, and adjust the reaction conditions reasonably to obtain the target product 2-cyano-3-cyano-5-trifluoromethylpyridine. After each step of the reaction, the product needs to be carefully separated and purified to ensure the smooth progress of the reaction and the purity of the final product.

2-%-3-amino-5-trifluoromethylpyridine is an important organic compound. When storing and transporting, many key matters need to be paid attention to.
First, it is related to storage. This compound is sensitive to environmental conditions and should be stored in a cool, dry and well-ventilated place. Due to humidity and high temperature, it is easy to cause chemical reactions or accelerate the process of deterioration. Be sure to keep away from fire and heat sources to prevent the risk of fire and explosion. Because of its certain chemical activity, it comes into contact with strong oxidants, strong acids, strong bases and other substances, or causes violent reactions. Therefore, it should be stored separately from such substances when storing, and follow the guidelines for classification and storage of chemical substances. At the same time, storage containers should also be carefully selected, and corrosion-resistant materials should be used, such as specific plastic or metal containers, to prevent the container from being corroded and causing material leakage. Containers must be tightly sealed to avoid excessive contact with air to prevent oxidation or other gas-phase reactions.
Second, involves transportation. Before transportation, make sure that the compound is properly packaged. Packaging materials must have good protective properties, can resist vibration, collision and friction, and prevent material leakage caused by package damage. During transportation, temperature and humidity conditions should be strictly controlled, and professional temperature control and humidity adjustment equipment can be used to maintain appropriate environmental parameters. Transportation vehicles must also meet relevant safety standards and be equipped with necessary fire equipment and leakage emergency treatment equipment. The escort personnel should be professionally trained and familiar with the characteristics of the compound and emergency treatment methods. In the event of an emergency such as a leak, they can respond quickly and correctly to reduce the harm. In addition, transportation route planning should not be ignored, and densely populated areas and environmentally sensitive areas should be avoided as much as possible to prevent large-scale damage in the event of an accident.

Today there are 2-chloro-3-chloromethyl-5-trifluoromethylpyridine. The impact of this substance on the environment and human health cannot be ignored.
The properties of this substance, its chlorine and fluorine-containing groups, are chemically active. In the environment, because of its high stability, it is difficult to be rapidly degraded by natural forces. It may remain in the soil, water and atmosphere for a long time, causing environmental contamination. In the soil, it may cause changes in soil quality, affecting the growth of vegetation, hindering plant nutrient uptake, growth and development. At light, the branches and leaves wilt, at worst, the plants die, and the ecological balance is gradually lost. In water bodies, or dissolve into them, causing deterioration of water quality and worrying about the survival of aquatic organisms. Fish, shellfish, etc., or due to physiological disorders, reproduction is damaged, population numbers are decreasing, and the chain of aquatic ecology is broken.
As for personal health, exposure to this thing is very harmful. Through skin contact, or skin allergies, erythema, itching, swelling and pain follow. If you inhale its volatile gas, the respiratory tract will bear the brunt. Light coughing, asthma, and poor breathing can cause lung damage and respiratory failure in severe cases. If you eat it by mistake, gastrointestinal diseases will appear, nausea, vomiting, abdominal pain, diarrhea, and other diseases will be tortured, and even life-threatening. Long-term exposure to this environment increases the risk of cancer, because its chemical structure may cause mutations in human cells and cause tumors.
Therefore, the use and emission of 2-chloro-3-chloromethyl-5-trifluoromethylpyridine should be carefully controlled and strictly controlled to protect the environment and human well-being.
