Procedure

The procedure followed was analogous to part (b) of Example 1, with the exception that, before the cracking reaction, the mixture, together with the added water, was boiled under reflux for 50 minutes at 90° C. and under a correspondingly reduced pressure. 260 g of 4-ethylhexenoic acid (boiling point 139°-141° C./25) were obtained, corresponding to a yield of 84.1%, relative to 2-ethylbutanal which had reacted.
