How to store N-methylpyrrolidone

N-methylpyrrolidone is an organic solvent that should be properly stored to ensure its long-term stability and safety. The following are recommendations for storing N-methylpyrrolidone:

Temperature: N-methylpyrrolidone should be stored at room temperature, away from direct sunlight and high temperature environments. Avoid exposing it to extreme temperatures to avoid volatilization and decomposition.

Sealing: Ensure that the container is tightly sealed to prevent evaporation and oxidation. Use well sealed glass bottles or acid resistant plastic bottles for storage.

Avoid moisture: N-methylpyrrolidone is prone to moisture absorption, so contact with moisture in the air should be avoided. Desiccants such as dry gas phase shielding agents or silicone can be added to the container to reduce the impact of moisture.

Keep away from ignition sources: N-methylpyrrolidone is a flammable liquid and should be kept away from open flames, sparks, and high temperature areas to prevent fire or explosion.

Storage area: Store N-methylpyrrolidone in a well ventilated area, away from flammable materials and oxidants. Ensure that the storage area is dry, clean, and equipped with appropriate firefighting equipment.

Identification: Clearly mark the name and hazard label of N-methylpyrrolidone on the container to identify and prevent accidents.

Please note that the above suggestions are for reference only, and specific storage requirements may vary depending on different laboratories and regulations. Before storing N-methylpyrrolidone, it is recommended to refer to the chemical's safety data sheet and relevant regulations to ensure proper handling and storage.
