Introduction

Also known as: cyclohexanone, pimelic ketone, ketohexamethylene.

Most cyclohexanone is used in the production of precursors to Nylon 66 and Nylon 6. About half of the world’s supply is converted to adipic acid, one of two precursors for nylon 66.

Cyclohexanone is also converted to the oxime. In the presence of sulfuric acid catalyst, the oxime rearranges to caprolactam.
 

General details

Specification

Cyclohexanone Specification sheet

Cyclohexanone is supplied in new steel drums – meeting UN packing standards – from a local source and utilising a newly installed drum filling facility.    

Source

Cyclohexanone is the ketone portion of ketone alcohol. It is an intermediate chemical produced in combination with cyclohexanol by the oxidation of cyclohexane and used in the production of adipic acid.

Cyclohexanone available to Valetime is derived from the chemical complex at Severodonetsk, Ukraine – the source of Adipic Acid and other key products.
