Cycloheptanone is a chemical compound from the group of ketones.

Production and representation

Cycloheptanone was the first time in 1836 by the French chemist Jean -Baptiste Boussingault starting from the calcium salt of suberic acid dibasic. For this he received Calciumsuberat by heating ( "dry distillation " ) calcium carbonate and Cycloheptanone:

Cycloheptanone can also be obtained by cyclization and decarboxylation of suberic acid or esters thereof. And synthesis by a reaction starting from cyclohexanone with sodium ethoxide and nitromethane, and further reaction with sodium nitrite and acetic acid is also possible. Furthermore, it may be obtained by ring expansion of cyclohexanone with diazomethane.

Properties

Cycloheptanone is a colorless flammable liquid with a fruity odor, which is practically insoluble in water.

Use

Cycloheptanone is used as intermediate for the preparation of other chemical compounds such as bencyclane, and pimelic acid.

Biological Significance

Various microorganisms, including Echinosporangium transverse, Absidia glauca and Mucor plumbeus, are able to reduce Cycloheptanone to Cycloheptanol.

Safety

The vapors of Cycloheptanone can combine with air to form an explosive mixture (flash point 55 ° C).
