Versuchsvorschrift
4-Methyl cyclohexanepropanal was similarly prepared as described in Examples I and II. First, 4-methyl benzaldehyde (140 g, commercially available from Mitsubishi Gas Chemical America, Inc.) was used to obtain 3-(4-methyl-phenyl)-propionaldehyde (130 g) with a boiling point of 120° C. at a pressure of 21 mmHg 3-(4-Methyl-phenyl)-propionaldehyde (180 g) was consequently used to provide 4-methyl cyclohexanepropanal (104 g) with a boiling point of 112° C. at a pressure of 24 mmHg
