2-Cyclopenten-1-one, 3-methyl-2-(2-pentenyl)-, (Z)-(488-10-8). It exists in the volatile oil extracted from jasmine flowers, including jasmine oil (containing about 3%), orange blossom oil, longevity flower oil, bergamot oil, and peppermint oil. It can be used to prepare jasmine essence, etc.

Application: 

Cisminone is one of the valuable spices. Its fragrance is very similar to that of jasmine flowers. It is one of the important fragrance ingredients of jasmine oil and is used in the essence of high-grade jasmine series products. Hydroreduction of jasmonic acid yields dihydrojasmonic acid. Dihydrojasmonate is a slightly colored transparent liquid with a boiling point of 230 ℃ and 102 ℃ (0.67kPaChemicalbook). It has a very strong flower fragrance and relatively stable chemical properties. It can be widely used in jasmine series essence. Dihydrojasmonate is simple in industrial production and has a variety of methods. In the presence of phosphoric acid, the temperature is controlled at 80 ℃ and the pressure is 0.007-0.011MPa to cyclize undecylenic acid to produce dihydrojasmonic acid.

Production method:

2-3-yl-cyclopentenone is synthesized by cyclization of 7-decene - γ - in methanol in the presence of sodium hydroxide, followed by the introduction of a methyl group.
