The synthesis method of 2-pyridineformonitrile and 3-nitro can be started from pyridine. Take pyridine first, put it in an appropriate reaction vessel, and add an appropriate amount of nitrifying reagent, such as the mixed acid of concentrated nitric acid and concentrated sulfuric acid. Under the condition of low temperature and careful temperature control, slowly add the mixed acid dropwise. Due to the violent nitrification reaction, careful operation is required to prevent runaway. The electron cloud distribution on the pyridine ring makes it easy for the nitro to be replaced in the 3-position. After a period of reaction, the reaction progress is monitored by thin-layer chromatography and other means. When the reaction reaches the expected level, the reaction liquid is carefully poured into the ice water to stop the reaction and promote the precipitation of the product. Next, the organic phase is extracted with an appropriate organic solvent, such as dichloromethane, and dried with a desiccant such as anhydrous sodium sulfate. Subsequently, the solvent is removed by reduced pressure distillation, and the crude product is further purified by column chromatography. A suitable eluent is selected to obtain pure 3-nitropyridine.
Then, 3-nitropyridine is reacted with a cyanide reagent, such as cuprous cyanide, in a specific organic solvent, such as N, N-dimethylformamide (DMF), at a suitable temperature and in the presence of a catalyst. Continuous stirring is required during the reaction to ensure full contact of the reactants. The reaction was also monitored by thin layer chromatography. When the reaction was completed, the reaction liquid was cooled, diluted with water, and then extracted with an organic solvent to separate the organic phase. After drying, it was purified by reduced pressure distillation and column chromatography to obtain 2-pyridinonitrile and 3-nitro products. In this way, the synthesis of 2-pyridinitrile and 3-nitro was achieved through two-step reaction of nitrification and cyanide.

2-Pyridineformonitrile, 3-nitro This substance, when storing and transporting, need to pay attention to many matters. It is a chemical substance with specific chemical properties and latent risks.
When storing, the first choice of environment. It should be placed in a cool, dry and well-ventilated place. Because the substance may be sensitive to heat, humidity, high temperature and humidity, or cause its chemical properties to change, and even cause dangerous reactions. And should be kept away from fire, heat sources, open flames and hot topics or cause them to burn and explode.
Furthermore, storage needs to be classified and stored. Do not mix with oxidants, acids, alkalis, etc., because of their chemical activity, contact with these substances, or react violently. At the same time, the storage area should be equipped with suitable containment materials to prevent leakage accidents, timely treatment, control the spread of hazards.
When transporting, the packaging must be solid. Ensure that the container is well sealed and there is no risk of leakage. The selected packaging materials must be able to withstand bumps and vibrations during transportation. Transportation vehicles must also meet safety standards and be equipped with corresponding fire fighting equipment and leakage emergency treatment equipment.
Transportation personnel must undergo professional training and be familiar with the characteristics of the substance and emergency treatment methods. During driving, avoid violent operations such as sudden braking and sharp turning to prevent package damage. And the transportation route should avoid sensitive areas such as densely populated areas and water sources to reduce the impact of accidents. In this way, the safety of 2-pyridinonitrile and 3-nitro is guaranteed during storage and transportation.
