[Chemical Properties]

Methylheptenone is a colorless to pale yellow oily liquid with a fruity and lemongrass aroma similar to amyl acetate. A certain amount of acetone can be generated after oxidation. The boiling point is 173-174°C or 73°C (2400Pa), and the melting point is -67.1°C. Flash point 50 ℃.
[Uses]

GB 2760--1996 stipulates that the edible spices are allowed to be used. Methylheptenone is mainly used to prepare flavors such as bananas, pears, citrus and berries, nuts and vegetables.
[Synthesis]

Methylheptenone is obtained by fractionating the essential oil containing the product (such as lemongrass oil), taking the fraction at 160-180°C and treating it with sodium bisulfite.
