Acetoacetic Acid → HCID 54178366, compound

Participants

Reaction Steps

A mixture of 11 parts of 2,7-dimethyl-1,4-diacetoxyocta-2,7-diene, 35 parts of water and 4.3 parts by volume of 1N hydrochloric acid (0.1 equivalent of HCl, based on 1 mole of the diacetate) is refluxed for 4 hours. An aldehyde/water mixture is then taken off, as described in Example 1. The resulting organic phase is fractionally distilled, and 4.3 parts (65% of theory) of 2,7-dimethylocta-2,6-dienal of boiling point 80°-82° C./16 mbar, nD20 =1.4776, are obtained.
