To prepare 1- (4-hydroxyphenyl) -1H-pyrrole-2,5-dione, the method is as follows:
Usually 4-hydroxybenzaldehyde and maleic anhydride are used as starting materials. First, 4-hydroxybenzaldehyde and maleic anhydride are mixed in an appropriate solvent, such as pyridine, and catalyzed by an appropriate catalyst, such as a catalytic system composed of acetic anhydride and sodium acetate, heated for azeotropic reflux. During this period, the aldehyde group of 4-hydroxybenzaldehyde undergoes a condensation reaction with maleic anhydride. The anhydride bond of maleic anhydride is opened, and the pyrrole ring is gradually constructed with 4-hydroxybenzaldehyde through a series of processes such as nucleophilic addition After the reaction is completed, the solid precipitates after cooling, and the crude product is filtered.
Compound with a suitable solvent for recrystallization, such as ethanol-water mixed solvent, control the appropriate ratio, heat to dissolve the crude product, and then slowly cool to allow the crystals to precipitate, filter and dry to obtain a relatively pure 1- (4-hydroxyphenyl) -1H-pyrrole-2,5-dione. When operating, pay attention to the control of reaction temperature and time, the choice and dosage of solvent, and the proportion of catalyst are also related to the effect of the reaction. When carefully weighed, the yield and purity can be better.

1 - (4-hydroxyphenyl) -1H-pyrrole-2,5-dione, this substance involves many safety precautions and needs to be treated with caution.
It is chemically active and should be protected first during operation. When added with appropriate protective equipment, such as chemical-resistant gloves, it can prevent it from making contact with the skin and prevent skin from being invaded and causing allergies and burns; protective glasses are also indispensable, which can prevent it from splashing into the eyes and protect the safety of the eyes. And the operation is suitable for a well-ventilated place. If it is in a closed place, its volatile gas will gather and not disperse, and it will be harmful to health if it enters the body.
Furthermore, its storage is also exquisite. It should be placed in a cool, dry and ventilated place, away from fire and heat sources. Due to its active chemical nature, it is dangerous to burn or even explode in case of heat or open flame. At the same time, it should be placed separately from oxidizing agents, reducing agents and other substances to avoid accidents caused by their interaction.
In terms of waste disposal, it must not be discarded at will. It must be properly collected and disposed of in accordance with relevant regulations and standards. Because it may contain harmful ingredients, if it is discarded in nature, seeps into water and soil, pollutes the environment and is harmful to the ecology.
And because of its potential toxicity, it is necessary to strictly control the dose and contact time during experimental research. Researchers should be aware of its nature and hazards, operate according to norms, and record the process and results in detail after the experiment, so as to trace and evaluate the risk. In this way, it can be used to ensure safety.
