Disclosed is process for the treatment of cyclopropanecarboxaldehdye (CPCA) which contains crotonaldehyde impurity with a base at elevated temperature to convert the crotonaldehyde to one or more higher boiling compounds followed by distillation to recover CPCA substantially free of crotonaldehyde. This selective reaction may be combined with a distillation to purify CPCA or in combination with the reaction of the CPCA in the treated mixture to produce a CPCA-derivative while avoiding or minimizing the formation of the analogous crotonaldehyde derivative.
