Here
are the details for cyclohexanone, which has the molecular formula (CH₂)₅CO:
Chemical Information:
- Chemical Name: Cyclohexanone
- CAS Number: 108-94-1
- Molecular Formula: C₆H₁₀O
- Structure: A six-membered
cyclohexane ring with a ketone functional group (C=O).
Physical Properties:
- Molecular Weight: 98.15 g/mol
- Appearance: Colorless to pale
yellow liquid
- Odor: Acetone-like odor
- Density: 0.9478 g/cm³ at 20°C
- Melting Point: -26°C
- Boiling Point: 155.6°C
- Solubility: Slightly soluble
in water; fully miscible with organic solvents such as ethanol, acetone,
and ether.
Chemical Properties:
- Reactivity: Cyclohexanone is
a stable ketone but can undergo typical ketone reactions, such as
nucleophilic addition and condensation. It can be oxidized to adipic acid
and reduced to cyclohexanol.
- Flammability: Flammable
liquid with a flash point of 46°C.
Uses:
- Nylon Production: Used as an
intermediate in the production of nylon 6 and nylon 66 by oxidation to
adipic acid or through cyclohexanol.
- Solvent: Employed as a
solvent for paints, coatings, and resins due to its good solvency and
moderate evaporation rate.
- Chemical Intermediate: Used
in the synthesis of pharmaceuticals, herbicides, plasticizers, and other
chemicals.
- Laboratory Reagent: Utilized
as a reagent and solvent in various chemical reactions and analytical
procedures.
Safety Information:
- Hazards: Cyclohexanone is an
irritant and can cause irritation to the skin, eyes, and respiratory
system. Prolonged exposure can lead to central nervous system depression
and liver or kidney damage.
- Handling: Should be handled
with appropriate protective equipment, including gloves, goggles, and
protective clothing. Use in a well-ventilated area or fume hood to avoid
inhalation of vapors.
- Storage: Store in a cool, dry
place away from sources of ignition and strong oxidizing agents.
Containers should be kept tightly closed to prevent evaporation and
contamination.
Environmental Impact:
- Biodegradability:
Cyclohexanone is readily biodegradable.
- Ecotoxicity: It can be toxic
to aquatic life in high concentrations, and care should be taken to
prevent its release into the environment.
Regulatory Information:
- OSHA PEL: 25 ppm (100 mg/m³)
- ACGIH TLV: 25 ppm (100 mg/m³)
Cyclohexanone
is a versatile chemical widely used in industrial applications, particularly in
the production of nylon and as a solvent. Proper handling, storage, and
disposal are essential to ensure safety and environmental protection.
