Water → 4-Cyanobenzaldehyde

Participants

Reaction Steps

39.6 g of p-cyanobenzylamine, 21.1 g of hexamethylenetetramine, 150 ml of water and 150 ml of acetic acid were mixed and reacted at 100° C. for 2 hours while stirring. The reaction solution was concentrated to a half amount in an evaporator and 300 ml of water was added to precipitate crystals. The crystals precipitated were collected by filtration, washed with water and dried to obtain 32.8 g (yield: 82%) of p-cyanobenzaldehyde. The purity was 99.5% or more.
