| Cycloheptanone Usage And Synthesis |
Chemical Properties | clear colorless to yellow liquid | Uses | Cycloheptanone is used as a precursor for the synthesis of pharmaceuticals. A spasmolytic agent and vasodilator is produced from this chemical. They are also used in certain stereospecific enzymatic reactions. | Synthesis Reference(s) | Canadian Journal of Chemistry, 47, p. 145, 1969 DOI: 10.1139/v69-016 Journal of the American Chemical Society, 98, p. 6717, 1976 DOI: 10.1021/ja00437a059 | Synthesis | Cycloheptanone is produced
by cyclization and decarboxylation of suberic
acid (1,8-octanedioic acid) or suberic acid esters
in the gas phase at 400 – 450℃ over alumina
doped with zinc oxide or cerium oxide. | Purification Methods | Shake suberone with aqueous KMnO4 to remove material absorbing around 230-240nm, then dry it with Linde type 13X molecular sieves and fractionally distil it through a glass helix packed column.
