Benzal chloride is a chemical compound from the group of aromatic chlorinated halocarbons (more precisely, the chlorinated toluene derivatives ). It is in the form of an air weak fuming colorless liquid.

Production and representation

Benzal chloride can be illustrated by toluene for benzyl chloride by free radical chlorination ( Seitenkettenhalogenierung radical ), where benzotrichloride formed.

In an optimized reaction conditions, the reaction is below the boiling point of benzal chloride and chlorinated under photochemical conditions in the gas phase, however, there arises practically only benzal chloride.

Properties

Hydrolysis of benzal chloride produced benzaldehyde:

With strong bases phenylcarbene forms.

Use

Benzal chloride is used for the production of benzaldehyde, cinnamic acid, and others.

Proof

Benzal chloride can be detected by gas chromatography.
