Water → 4-Cyanobenzaldehyde

Participants

Reaction Steps

39.6 g of p-cyanobenzylamine, 42.1 g of hexamethylenetetramine, 200 ml of water and 200 ml of acetic acid were mixed and reacted at 100° C. for 2 hours while stirring. The reaction solution was allowed to stand overnight and as a result, scale-like crystals were precipitated. The crystals precipitated were collected by filtration, washed with water and dried to obtain 24.7 g (yield: 62%) of p-cyanobenzaldehyde. The purity was 99.8% or more.
