To make 2,3-pyrazine dicarboxylic acid, you can follow the following ancient method. First take an appropriate amount of pyrazine as the base material, which is the key to starting. In a suitable container, add a strong oxidizing agent, such as potassium permanganate, which has strong oxidizing properties and can help the reaction progress smoothly.
Then, carefully adjust the reaction temperature and duration. The temperature should be stable in a specific range, and it should not be too high to cause material loss or product decomposition, nor too low to cause slow reaction. The duration also needs to be precisely controlled. If it is too short, the reaction will not be complete, and if it is too long, it may cause side reactions.
During the reaction process, pay close attention to the reaction phenomena, such as color changes, bubble generation, etc., to judge the reaction situation.
