Method of producing cyclododecanone compound

A cyclododecanone compound is produced in a high reaction rate, with a high conversion of the starting compound, and with a high selectivity to and a high yield of the target compound by isomerizing an epoxycyclododecane compound in the presence of a catalyst comprising lithium bromide and/or lithiu...

More Information
Summary:A cyclododecanone compound is produced in a high reaction rate, with a high conversion of the starting compound, and with a high selectivity to and a high yield of the target compound by isomerizing an epoxycyclododecane compound in the presence of a catalyst comprising lithium bromide and/or lithium iodide, without using a solvent or in a non-polar solvent, in an inert gas atmosphere, while substantially no polymeric compounds having a high boiling temperature is produced.
