Alpha-Methylstyrene

Alpha-Methylstyrene (AMS) is an organic compound with the formula CH₃C₆H₄CH=CH₂. It is a colorless liquid with a sweet smell. It evaporates easily and is not soluble in water. Alpha-Methylstyrene is used as a component in some plastics, resins, and polymers.

Production

Alpha-Methylstyrene is produced as a byproduct in the production of phenol and acetone via the cumene process. This process involves the alkylation of benzene with propylene to produce cumene, which is then oxidized by air to produce phenol and acetone. The remaining cumene is dehydrogenated to produce alpha-methylstyrene.

Uses

Alpha-Methylstyrene is used as a co-monomer in the production of a variety of resins and plastics. It is also used as a raw material in the manufacture of some chemicals, including plasticizers, resins, and polymers. In addition, it is used in the production of heat-resistant and impact-resistant materials.

Health Effects

Exposure to alpha-methylstyrene can cause irritation to the eyes, skin, and respiratory tract. It can also cause headache, dizziness, and nausea. Long-term exposure can lead to more serious health effects, including damage to the liver and kidneys.

Safety

Alpha-Methylstyrene is a flammable liquid and its vapors can form explosive mixtures with air. It should be stored in a cool, well-ventilated area away from sources of ignition.
