Cyclohexane CAS 110-82-7

Cyclohexane, with the Chemical Abstracts Service (CAS) number 110-82-7, is a colorless, flammable liquid that is primarily used as a solvent and as an intermediate in the production of various chemicals, notably nylon.
Properties of Cyclohexane
Chemical Formula: C₆H₁₂
Molecular Weight: Approximately 84.16 g/mol
Density: About 0.7739 g/mL at 25°C
Boiling Point: Approximately 80.7°C
Melting Point: Around 6.47°C
Solubility: Cyclohexane is non-polar and is not soluble in water, but it is soluble in organic solvents like alcohol and acetone.
Uses of Cyclohexane
Cyclohexane is predominantly utilized in the following applications:
Nylon Production: Over 90% of cyclohexane produced is used to manufacture intermediates for nylon, specifically through the production of adipic acid and caprolactam. Adipic acid is crucial for nylon-6,6, while caprolactam is used for nylon-6.
Solvent: It serves as a non-polar solvent for various applications, including lacquers, resins, and paint removers. Its properties make it suitable for use in chemical and industrial processes, often replacing benzene in many applications due to safety concerns.
Chemical Intermediate: Cyclohexane is also involved in the synthesis of other chemicals, including plasticizers and synthetic lubricants.
Safety and Environmental Impact
Cyclohexane is flammable and can pose health risks upon exposure. Inhalation may lead to symptoms such as dizziness, headaches, and respiratory irritation. Prolonged skin contact can cause irritation, while ingestion may result in gastrointestinal upset.
It is important to handle cyclohexane with care, following appropriate safety guidelines to minimize exposure and environmental impact. Cyclohexane can enter the environment through natural sources and industrial processes, necessitating careful management to prevent contamination.
In summary, cyclohexane is a versatile chemical with significant industrial applications, particularly in the production of nylon and as a solvent, while also requiring careful handling due to its flammable nature and potential health risks.
