⚗️ Chemical & Physical Properties
Pyrrolidine is a colorless to slightly yellow liquid with a distinctive ammonia-like odor. It is commonly used as a building block in the synthesis of pharmaceuticals and agrochemicals due to its versatile chemical reactivity.
With a molar mass of approximately 71.12 g/mol and a density of around 0.866 g/cm3, pyrrolidine is significantly heavier than common food items like water and milk. Its higher density makes it useful in various industrial applications, such as solvents and chemical intermediates.
Pyrrolidine has a melting point of -63.5°C and a boiling point of 87.4°C. These values are lower than those of many common food items, indicating a lower energy requirement for phase change. This can be advantageous in chemical processes that involve heating and cooling.
Pyrrolidine is highly soluble in water and has a low viscosity, making it easy to handle in laboratory settings. In comparison to common food items, it exhibits greater solubility in water than substances like salt or sugar, and lower viscosity than liquids such as honey or syrup.
🏭 Production & Procurement
First synthesized in 1857 by the chemist V. T. da Pont, Pyrrolidine is commonly produced through the catalytic reduction of pyrrole. This process involves reacting pyrrole with hydrogen gas in the presence of a catalyst, typically palladium or platinum, to yield Pyrrolidine.
Pyrrolidine can be procured through various chemical suppliers or specialty manufacturers. It is commonly transported in liquid form in sealed containers to prevent contamination or evaporation during transit. Transport methods may include ground shipping or air freight, depending on the quantity and urgency of the order.
Upon reaching its destination, Pyrrolidine must be stored in a cool, dry place away from heat and direct sunlight to maintain its stability and purity. Proper handling procedures should be followed to minimize the risk of exposure to this chemical compound. It is essential to adhere to safety protocols and regulations when working with Pyrrolidine to ensure the health and well-being of individuals involved in its production and use.
