3-Methyl-2-buten-1-OL → 3,7-Dimethylocta-2,6-Dienal

Participants

Reaction Steps

A mixture of 600 parts of 3-methyl-2-buten-1-ol and 300 parts of 3,3-dimethylacrolein is pumped through a reactor having a capacity of 150 parts by volume with a residence time of seven minutes. The reaction temperature is 250° C. and the presence is 150 atmospheres. The reaction mixture which has reacted is fractionally distilled and 91.5 parts of citral is obtained. This is equivalent to a yield of 51% of theory based on 3,3-dimethylacrolein at a conversion of 33%.
