⚗️ Chemical & Physical Properties
Methylpyrrolidone, also known as N-Methylpyrrolidone or NMP, is a colorless liquid with a mild amine-like odor. It is a polar aprotic solvent commonly used in a variety of industrial applications, including chemical reactions, coatings, and pharmaceuticals.
The molar mass of Methylpyrrolidone is approximately 99.13 g/mol, and its density is around 1.028 g/cm³ at room temperature. Compared to common food items like sugar (molar mass ~342.3 g/mol, density ~1.59 g/cm³) and salt (molar mass ~58.44 g/mol, density ~2.16 g/cm³), Methylpyrrolidone has a lower molar mass and density.
Methylpyrrolidone has a melting point of -24°C and a boiling point of 202-204°C. In contrast, common food items like butter (melting point ~32-35°C, boiling point ~160°C) and water (melting point 0°C, boiling point 100°C) have lower melting and boiling points.
Methylpyrrolidone is highly soluble in water and has a high viscosity, making it a useful solvent in various applications. Compared to common food items like sugar (soluble in water, low viscosity) and oil (insoluble in water, high viscosity), Methylpyrrolidone exhibits different solubility and viscosity properties in aqueous solutions.
🏭 Production & Procurement
Methylpyrrolidone, also known as N-methyl-2-pyrrolidone or NMP, is commonly produced through a reaction between γ-butyrolactone and methylamine. This process involves the removal of water and excess amine to yield the final product of Methylpyrrolidone.
Methylpyrrolidone can be procured through various chemical suppliers and manufacturers worldwide. The transportation of Methylpyrrolidone typically involves packaging in drums, isotanks, or bulk containers for safe and efficient delivery to customers. Due to its versatility and wide range of applications, Methylpyrrolidone is readily available in the industrial market.
The procurement of Methylpyrrolidone may also involve custom synthesis for specific applications or formulations. Some companies may offer tailor-made solutions for customers seeking specialized grades or quantities of Methylpyrrolidone. Additionally, the transportation of Methylpyrrolidone may require adherence to regulatory standards and guidelines for safe handling and delivery.
⚠️ Safety Considerations
Safety considerations for Methylpyrrolidone should be taken seriously due to its potential hazards to human health. When working with Methylpyrrolidone, it is important to use appropriate personal protective equipment, such as gloves and goggles, to prevent skin contact and inhalation of vapors. Additionally, Methylpyrrolidone should be stored in a well-ventilated area away from sources of ignition to reduce the risk of fire or explosion.
The hazard statements for Methylpyrrolidone include “Harmful if swallowed,” “Causes skin irritation,” and “May cause respiratory irritation.” These statements indicate that Methylpyrrolidone can pose risks to human health if proper precautions are not taken. It is important to handle Methylpyrrolidone with care and follow safety protocols to minimize the potential for harm.
Precautionary statements for Methylpyrrolidone include “Wash hands thoroughly after handling,” “Do not eat, drink, or smoke when using this product,” and “Use only outdoors or in a well-ventilated area.” These statements emphasize the importance of practicing good hygiene, avoiding ingestion of the chemical, and ensuring proper ventilation when working with Methylpyrrolidone. Following these precautions can help reduce the likelihood of accidents or injuries when handling this substance.
