1 - [2 - (2 - hydroxyethoxy) ethyl] - 1H - pyrrole - 2,5 - dione synthesis method, and need to imitate "Tiangong Kaiwu" in ancient text, this is a challenging chemical synthesis description task.
To prepare 1 - [2 - (2 - hydroxyethoxy) ethyl] - 1H - pyrrole - 2,5 - dione, you can follow the following steps. First take an appropriate amount of 2 - (2 - hydroxyethoxy) ethanol and place it in a clean reactor. The kettle is a chemical reaction instrument, and it is necessary to ensure that it is free of impurities and water stains to ensure the purity of the reaction.
Next, slowly add a certain amount of maleic anhydride. The amount of this material needs to be accurately measured, because its ratio is related to the effectiveness of the reaction. When adding, it should be done slowly, accompanied by moderate stirring, so that the two can be evenly mixed. Stirring, so that the material is mixed, and the reaction speed is also promoted.
Then, increase the temperature of the reactor to a certain value. Temperature control is crucial. If it is too high, the reaction will be excessive, and if it is too low, the reaction will be slow. Maintain this temperature and continue to stir for several hours. Time, the unit of time, here is the time required for the reaction.
After the reaction is completed, the reaction liquid is cooled. The method of cooling can be placed in a cold water bath and slowly cooled. Then, the reaction liquid after cooling is separated and purified. It can be recrystallized, extracted, etc. to remove its impurities and retain pure 1- [2- (2-hydroxyethoxy) ethyl] -1H-pyrrole-2,5-dione. For recrystallization, the pure substance is precipitated from the solution by the difference in solubility of the substance; for extractors, the desired substance is extracted with a specific solvent. After these steps, the target product can be obtained.

1 - [2- (2-hydroxyethoxy) ethyl] -1H-pyrrole-2,5-dione, this is a special chemical substance. When storing and transporting, many things should be paid attention to.
First storage, this substance should be placed in a cool, dry and well-ventilated place. Due to its nature, it may be sensitive to humidity and temperature. If placed in a humid place, or due to water vapor attack, its properties may be mutated; if exposed to high temperature, it may cause chemical reactions, or even endanger safety. Be sure to keep away from fire and heat sources to prevent the risk of fire and explosion. And it should be stored separately from oxidizing agents, acids, alkalis, etc., because it may react violently with these substances, causing changes in composition or harmful products.
As for transportation, extreme caution is also required. Packaging must be tight to ensure that no leakage will occur due to bumps and collisions during transportation. When transporting, relevant transportation regulations and standards should be followed, and suitable transportation tools should be selected. At the same time, transporters should be familiar with the characteristics of this substance and emergency treatment methods. In the event of leakage and other unexpected situations, they can dispose of it quickly and properly. If exposed to improper substances during transportation or encountered harsh environmental conditions, its quality and safety may be affected. In conclusion, the storage and transportation of 1 - [2 - (2 - hydroxyethoxy) ethyl] -1H - pyrrole - 2,5 - dione requires careful consideration of all factors to ensure its safety and quality.
