Here are the details for styrene:
- Chemical Name:Styrene
- CAS Number: 100-42-5
- Molecular Formula: C₈H₈
- Structure: It consists of a benzene ring (C₆H₅) attached to a vinyl group (CHCH₂).
Physical Properties:
- Molecular Weight: 104.15 g/mol
- Appearance: Colorless, oily liquid
- Odor: Sweet, aromatic odor
- Density: 0.909 g/cm³ at 20°C
- Melting Point: 30.6°C
- Boiling Point 145°C
- Solubility: Slightly soluble in water, but miscible with organic solvents such as ethanol and acetone.
Chemical Properties:
- Reactivity: Styrene can polymerize spontaneously
at room temperature, particularly in the presence of oxygen. Inhibited by
tert-butylcatechol (TBC) to prevent polymerization during storage.
- Flammability: Flammable liquid with a flash point of 31°C.
Uses:
- Polystyrene Production: Majorly used in the
production of polystyrene plastics and resins.
- Rubber: Used in the production of
styrene-butadiene rubber (SBR) for tires and other rubber products.
- Other Polymers: Utilized in the manufacture of copolymers like styrene-acrylonitrile (SAN) and acrylonitrile-butadiene-styrene (ABS).
Safety Information:
- Hazards: Styrene is a potential carcinogen and
exposure can cause irritation to the skin, eyes, and respiratory system.
- Handling: Should be handled with proper
protective equipment in a well-ventilated area to avoid inhalation and skin
contact.
- Storage: Store in a cool, dry place away from
sources of ignition and polymerization catalysts.
