HCID 178770343-(4-Ethylphenyl)propanal

Procedure

4-Ethyl cyclohexanepropanal was similarly prepared as described in Examples I and II. First, 4-ethyl benzaldehyde (925 g, commercially available from Mitsubishi Gas Chemical Company, Inc.) was used to obtain 3-(4-ethyl-phenyl)-propionaldehyde (878 g) with a boiling point of 129° C. at a pressure of 12 mmHg. 3-(4-Ethyl-phenyl)-propionaldehyde (350 g) was consequently used to provide 4-ethyl cyclohexanepropanal (201 g) with a boiling point of 85° C. at a pressure of 3 mmHg.
