The liquid density of dichloromethane is approximately 1.325 g/mL (at standard temperature and pressure). This value is experimentally determined and serves as a critical indicator for evaluating its applications and safety.
What is the density of dichloromethane solution?
Dichloromethane, with the chemical formula CH₂Cl₂, is a colorless, transparent, volatile liquid possessing a pungent odor. Its liquid density refers to the mass of dichloromethane per unit volume at standard atmospheric pressure and a specific temperature. Experimental measurements indicate that the liquid density of dichloromethane at standard temperature and pressure is approximately 1.325 g/mL. This density value classifies dichloromethane as a relatively heavy substance among liquids.

What affects dichloromethane density?
The density of dichloromethane solution is influenced by temperature and pressure. Generally, as temperature increases, molecular motion intensifies, leading to a decrease in density. Conversely, as pressure rises, the distance between molecules decreases, causing density to increase. Therefore, the density of DCM varies under different temperature and pressure conditions. For example, at 0°C, its density is 1.324 g/cm³; at 50°C, the density drops to 1.284 g/cm³.

What Is Dichloromethane? Common Uses and Safety Concerns
Dichloromethane is a colorless liquid with a slight chloroform-like odor. It is classified as a volatile liquid.
DCM has the chemical formula CH₂Cl₂. It is produced by heating chlorine and methane. It is also known by the following synonyms:
- Methylene chloride
- Methylene dichloride
- Methylene dichloride
The liquid density of dichloromethane (DCM) holds significant importance in its applications and safety assessments. As a vital organic solvent, DCM finds extensive use in industrial and everyday settings. Its density characteristics play a crucial role in preparing solutions, calculating volumes, and determining mass. Simultaneously, density serves as a key indicator for assessing DCM's safety, as it closely relates to properties like volatility and flammability.

dichloromethane solution Uses
However, dichloromethane solution is a toxic substance. Prolonged exposure may lead to health issues such as skin allergies, neurological damage, and cancer. Therefore, when handling dichloromethane, it is essential to wear protective gloves, masks, and goggles, and ensure use occurs in a well-ventilated area to avoid skin and eye contact. Additionally, keep it away from children and pets to prevent accidents.
In summary, understanding the liquid density of dichloromethane and its influencing factors is crucial for its safe use and application. Strict adherence to safety protocols during handling is imperative to ensure personal safety.
