However, in water, its solubility is relatively limited, as if the embrace of water does not fully accept it, only a small amount of dissolution, which reflects the interaction between its molecular structure and water molecules.
Melting point is also its important physical property. It has a specific melting point range, and when heated to a certain temperature, it is like the ice and snow meeting the warm sun, and begins to gradually change from solid to liquid. This melting point temperature is relatively stable, just like the fixed Poseidon needle, providing an important basis for the identification and identification of the substance. By accurately measuring the melting point, its purity can be judged. If the purity is high, the melting point range is narrow and close to the theoretical value; if it contains impurities, the melting point decreases and the range becomes wider.
Its density is also fixed, and it is in a specific range compared with the density of common organic compounds. The density reflects the compactness of the particles inside the substance, just like the density of the population.

The method of preparing 3-pyridineformamide, $N $, $N '$- (1-methyl-1,2-ethylenediyl) bis - has been known for a long time.
First take pyridine3-formic acid, place it in a clean kettle, and adjust its pH with an appropriate agent to reach a suitable environment. Then add a specific condensing agent and stir well. The amount of this condensing agent needs to be precisely controlled, which is related to the success or failure of the reaction. When stirring, slowly raise the temperature and observe the reaction. The temperature should not be too high or too low. If it is too high, it is easy to cause side reactions to cluster, and if it is too low, the reaction will be slow and difficult.
At the same time, add 1-methyl-1,2-ethylenediamine dropwise to the kettle at a suitable rate. Pay attention to the speed of dropwise addition. If it is too fast, the reaction will be too aggressive, and if it is too slow, it will take too long. After the dropwise addition is completed, continue to stir to fully blend the reactants and react.
When the reaction is approaching the end, separate and purify the products in an exquisite way. You can first use distillation to remove its volatile impurities, and then use recrystallization to take a suitable solvent, so that the product is recrystallized in it, and pure crystals are precipitated. After multiple recrystallization, high-purity 3-pyridineformamide, $N $, $N '$- (1-methyl-1,2-ethylenediyl) bis- can be obtained. When operating, you must pay attention to the cleanliness of the surrounding environment to prevent impurities from mixing and damaging the purity of the product. And every step must follow the law, and there must be no slack, so that you can get a good product.
