50 Parts of citral and 100 parts of acetone are reacted for 45 minutes at 200° C and a pressure of 80 atmospheres in the presence of 12 parts of a catalyst consisting of 12% by weight of copper(II) oxide and 88% by weight of zinc oxide. 45.6 parts of pseudoionone having a boiling point of 90° C at 0.01 mm is obtained analogously to Example 1. The conversion is 82% of theory and the yield based on citral is 88% of theory.
