[PDF] acid hydrolysis of nitriles conditions

Acidic Hydrolysis of Nitriles Under acidic conditions, instead of getting an ammonium salt, carboxylic acid is formed. For example, Ethanenitrile on getting hydrolysed in hydrochloric acid gives ethanamide in the first step, while ethanoic acid and ammonium chloride in the second step.

  • What are the basic conditions for nitrile hydrolysis?

    The basic hydrolysis of a nitrile to a carboxylic acid is typically done with a hydroxide base (ex. NaOH or KOH) in an appropriate solvent (ex. EtOH/H2O) at high temperatures (ex. reflux).

  • What are the conditions for acid hydrolysis?

    This hydrolysis can occur under acidic or basic conditions. Acidic hydrolysis is simply the reverse of esterification. The ester is heated with a large excess of water containing a strong-acid catalyst. Like esterification, the reaction is reversible and does not go to completion.

  • What is the best set of conditions to convert a nitrile to a carboxylic acid?

    Nitriles can be converted to carboxylic acid with heating in sulfuric acid. During the reaction an amide intermediate is formed.
  • Typical conditions for hydrolysis of an amide involve heating the amide with aqueous acid for extended periods. Cyclic amides are called, “lactams”. Just as undoing a belt results in a simple strip of leather, hydrolysis of a cyclic lactam results in a linear amino acid.
