The Chemical Properties and Specifications of Dichloromethane (CAS 75-09-2)
Dichloromethane (DCM), commonly known as Methylene Chloride (CAS 75-09-2), is a fundamental organic compound widely utilized across numerous industrial sectors. Its efficacy stems from a specific set of chemical properties and adherence to stringent specifications, ensuring its suitability for demanding applications.
At its core, dichloromethane is an organic compound with the chemical formula CH2Cl2. It presents as a colorless and transparent liquid, possessing a distinctive, moderately sweet odor. A key characteristic is its solubility profile: while it does not readily mix with water, it exhibits excellent miscibility with a broad spectrum of organic solvents. This property makes it an exceptionally versatile solvent, capable of dissolving a wide array of organic substances.
The specifications for industrial-grade dichloromethane are critical for its performance and safety. Typically, it is supplied with a high purity level, often exceeding 99.95% (Assay ≥ 99.95%). This high purity is essential for applications in sensitive fields such as pharmaceuticals and fine chemical synthesis, where even minute impurities can affect reaction outcomes or product quality.
Further specifications include limits on acidity and water content. The acidity, often measured as Acidity (HCl), is kept to a minimum, typically less than or equal to 0.0003%. Similarly, the water content is strictly controlled, usually at or below 0.01%. These low levels of acidity and moisture are vital for preventing unwanted side reactions and maintaining the stability of dichloromethane during storage and use.
The color quality of the solvent is also a specified parameter. Measured using the Chroma (pt-Co) scale, it is maintained at a low level, typically ≤ 10, indicating a clear and colorless appearance. This visual clarity is an important indicator of purity and quality for users.
Beyond its solvent capabilities, dichloromethane also possesses a characteristic volatility. This property aids in its easy removal from processed materials through evaporation, a significant advantage in applications like extraction and cleaning. Its low boiling point facilitates this process, contributing to efficient industrial workflows.
Understanding these chemical properties and specifications is crucial for anyone involved in the procurement or use of dichloromethane. The high purity, controlled acidity, low water content, and effective solvency are all key factors that define its value in industrial applications, from chemical synthesis and pharmaceutical manufacturing to metal cleaning and degreasing.
