BENZAL CHLORIDE (98-87-3) is a colourless oily liquid lachrymator. It has many synonyms such as Benzyl dichloride ; BENZYLIDENE CHLORIDE ; BENZYLIDENE DICHLORIDE ; BENZAL CHLORIDE ; (DICHLOROMETHYL)BENZENE ; ALPHA,ALPHA'-DICHLOROTOLUENE ; ALPHA,ALPHA-DICHLOROTOLUENE ; A,A-DICHLOROTOLUENE, etc. It can be used as a building block in organic synthesis. BENZAL CHLORIDE (98-87-3) is produced by the free radical chlorination of toluene , being preceded in the process by benzyl chloride and followed by benzotrichloride :
C6H5CH3 + Cl2 → C6H5CH2Cl + HCl
C6H5CH2Cl + Cl2 → C6H5CHCl2 + HCl
C6H5CHCl2 + Cl2 → C6H5CCl3 + HCl
Howere, most benzal chloride is hydrolysed to benzaldehyde :
C6H5CHCl2 + H2O → C6H5CHO + 2 HCl
