Abstract
Cycloheptanone (suberone) is prepared by first evaporating suberic-acid esters which are reacted in alcoholic and/or aqueous dilution in the gas phase on aluminum oxide support catalyst doped with zinc oxide and/or cerium oxide at temperatures between 300.degree. and 600.degree. C.

A process for the preparation of cycloheptanone from a suberic-acid ester, comprising evaporating a suberic-acid ester and reacting said ester in the gas phase on aluminum oxide support catalysts doped with a catalytic amount of an oxide selected from the group consisting of zinc oxide, cerium oxide or a mixture thereof at temperatures between 300.degree. and 600.degree. C. and diluting said evaporated ester with a compound selected from the group consisting of alcohol, water or a mixture thereof.
