Chlorobenzene, with the CAS number 108-90-7, is an aromatic organic compound characterized by its chemical formula C₆H₅Cl. It appears as a colorless, flammable liquid that has a distinctive almond-like odor. Here are some key details about chlorobenzene:
Physical and Chemical Properties
Molecular Weight: 112.56 g/mol
Boiling Point: Approximately 131.69°C
Freezing Point: -45.58°C
Vapor Pressure: 8.8 Torr at 20°C
Solubility: Chlorobenzene is only slightly soluble in water but readily evaporates into the air.
Uses
Chlorobenzene is primarily used as a solvent in various industrial applications. It serves as a solvent in the production of dyes, pesticides, and rubber, and is also utilized as a chemical intermediate in the synthesis of other compounds.
Toxicity and Safety
Chlorobenzene is classified as a toxic substance. Chronic exposure can affect the central nervous system, leading to symptoms such as numbness and muscle spasms. Its LD50 (lethal dose for 50% of the population) is reported to be 2.9 g/kg, indicating moderate toxicity.
Regulatory Information
Chlorobenzene is regulated due to its potential health risks. Safety data sheets (SDS) and material safety data sheets (MSDS) are available for handling and exposure guidelines.
In summary, chlorobenzene is a versatile solvent with significant industrial applications, but it requires careful handling due to its toxic properties.
