For chemical professionals, a deep understanding of the properties of key solvents like Acetonitrile (CAS 75-05-8) is fundamental to ensuring process efficiency and safety. Acetonitrile, a colorless liquid, is the simplest organic nitrile and is widely employed as a polar aprotic solvent. Its chemical structure, CH3CN, grants it a unique set of characteristics that make it invaluable in organic synthesis and purification processes, notably for butadiene.

Key physical properties of acetonitrile include a density of 0.7857 g/cm³, a melting point of -46°C, and a boiling point of 81-82°C. Its flash point is a critical safety consideration at 2°C, classifying it as highly flammable. The refractive index typically ranges from 1.343-1.345, and it is miscible with water, showcasing its broad solvency capabilities. Stability is another important factor; while generally stable under recommended conditions, it is noted as unstable and incompatible with alkali metals, acids, bases, reducing agents, and oxidizing agents.

Understanding these acetonitrile properties is crucial for proper handling, storage, and application. The recommended storage condition is between 2-8°C to maintain its integrity and minimize hazards. Its vapor pressure is 72.8 mm Hg at 20°C, and its vapor density is 1.41 compared to air, indicating that its vapors are denser than air and can accumulate in low-lying areas.

When sourcing acetonitrile, it is vital to consider the acetonitrile product manufacturers and their adherence to quality standards. Working with a reliable acetonitrile supplier like NINGBO INNO PHARMCHEM CO.,LTD. ensures you receive a product that meets these critical specifications. Familiarizing yourself with the acetonitrile properties detailed here will empower you to utilize this versatile solvent safely and effectively in your chemical endeavors, whether for research or industrial production.
