Acetophenone is an organic compound, the simplest aromatic ketone. It has the formula C6H5C(O)CH3.

Properties

Chemical

Acetophenone is the precursor used in the manufacturing of styrene.

Physical

Acetophenone is a colorless liquid at temperatures higher than room temperature and a solid at lower temperatures, making it an interesting chemical compound.

Availability

Can be bought from chemical suppliers.

In Canada it's classified as schedule VI, class A precursor. Purchasing requires an EUD.

Preparation

An accessible route involves the pyrolysis of a mixture of calcium acetate and calcium benzoate. Another method is Friedel-Crafts acylation with anhydrous aluminium trichloride, acetyl chloride and benzene.

Projects

  • Nice smelling aromas
  • Make Biperiden

Handling

Safety

Acetophenone has low toxicity and its carcinogenicity hasn't been confirmed.

Storage

Should be kept in closed glass or plastic bottles.

Disposal

Acetophenone should be mixed with a more flammable solvent and incinerated.
