WebJan 23, 2024 · The reaction isn't normally done using hydrogen cyanide itself, because this is an extremely poisonous gas. Instead, the aldehyde or ketone is mixed with a solution of sodium or potassium cyanide in water to which a little sulphuric acid has been added. The pH of the solution is adjusted to about 4 - 5, because this gives the fastest reaction. WebOxime formation. Reaction of aldehydes and ketones with hydroxylamine gives oximes. The nucleophilicity of the nitrogen on the hydroxylamine is increased by the presence of the oxygen. Successive proton transfers allows for elimination of water. Oximes generally form a mixture of geometric isomers. S. Rosenberg, S. M. Silver, J. M. Sayer and W ...
