Procedure

The procedure followed was analogous to part (b) of Example 1, with the exception that (before the cracking reaction) the mixture was heated with 50 g of water at 90° C. for 60 minutes. 268 g of heptenoic acid (boiling point 139°-141° C./25) were obtained, corresponding to a yield of 84.8%, relative to valeraldehyde which had reacted.
