To prepare 2- (5-pyrrolidinedione-1-yl) iodine, the following ancient method can be used.
Take an appropriate amount of pyrrolidinedione and place it in a clean container. Melt pyrrolidinedione slightly at low temperature and slow heat to make the subsequent reaction easier.
Take another iodine-containing reagent, which needs to be pure and free of impurities to prevent affecting the reaction result. Slowly add the iodine-containing reagent to the container containing pyrrolidinedione. When adding, stir continuously to make the two fully mixed. The speed of stirring should not be too fast or too slow. If it is too fast, the reactants will be easily splashed out. If it is too slow, the mixing will be uneven, which will affect the reaction process.
During the reaction process, the temperature needs to be strictly controlled. This reaction is suitable for mild temperature. If the temperature is too high, the product will easily decompose or produce side reactions; if the temperature is too low, the reaction rate will be too slow and time-consuming. The temperature can be controlled by water bath or oil bath to keep the temperature constant within a certain range.
After the reaction has been carried out for a period of time, observe the reaction phenomena such as changes in the state and color in the container. When the reaction is roughly completed, remove the unreacted raw materials and by-products by appropriate separation and purification methods. Filtration, distillation, extraction and other methods can be used, depending on the specific situation. When filtering, the pore size of the filter paper needs to be suitable to prevent the loss of the product; when distilling, the control of temperature is crucial, and the boiling points of different substances are different, so they can be separated. The solvent of extraction needs to have a suitable solubility difference with the product and impurities in order to be effectively separated.
Through this series of steps, 2- (5-pyrrolidinedione-1-yl) iodine can be obtained. The whole process needs to be handled carefully, paying attention to the details of each step, in order to obtain satisfactory results.
