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