PIPERITONE Usage And Synthesis

Uses

Piperitone is a monoterpene compound that has a fresh minty camphor-like odour, and naturally occurs in extracts of commercial oil of peppermint. Piperitone is also used as a starting material in the synthesis of Thymol (T413000), a phenolic compound that is used for its antibacterial properties. The cyclic ketone is more commonly used in flavour compositions, particularly in spice complexes with Caraway, Estragon, etc., and in fruit complexes with mint flavours, etc. Now and then, it has become “fashionable” in dentifrice preparations where larger amounts are used. The concentration normally used is equivalent to about 1 to 20 ppm in the finished product.

Production Methods

Piperitone is produced:
by isolation from Japanese Mint oil (dextro-Piperitone),
by isolation from Eucalyptus dives oil (laevo-Piperitone),
by hydrogenation of Diosphenol,
by reduction of 5-Methyl-2-iso-propylanisole with Sodium in liquid Ammonia.
laevo-Piperitone can also be produced from laevo-beta-Pinene via l-Limonene, by hydrogenation to /-Carvomenthene, and via 4 further intermediate steps to Piperitone.

Definition
