Reaction between amine and aldehyde

WebThe aryl aldehyde is less reactive than an aliphatic aldehyde. Consequently, the aryl aldehyde is less likely to react with free amines to form a Schiff base. Moreover, a Schiff base between an aryl aldehyde and a free amine is easily reversed. This means that the aldehyde is free to react with a hydrazide or oxyamine group. WebThe hemiacetal bond that formed between the aldehyde group in DAC and the hydroxyl group could initially form a crosslinked network layer in the system. The internal cohesion …
