Uses
Uses in perfumery :
Year of discovery :
Data not available.
Natural availability :
Methyl Heptyl Ketone is present in fruits and spice such as banana, ginger, clove, coconut, tomato, corn, cheese, wine.. Thus, natural qualities are available
Isomerism :
Methyl Heptyl Ketone is the constitutional isomer of Cinnamaldehyde, although these two molecules do not smell the same.
Synthesis precursor :
A condensation of this ketone with another ketone may form the desired alkene. Hydrogenation of Methyl Heptyl Ketone can form 2-nonanol, also relevant in perfumery.
Synthesis route :
Methyl Heptyl Ketone can be synthesized by dry distillation of Barium Caprylate and Barium acetate at very low pressure (0.5 to 2 mmHg). Another method for synthesizing this compound is to use chromic acid, reacting with methyl heptyl carbinol at room temperature, to oxidize the latter.
