Cyclohexanone Manufacture Process

High concentrations of cyclohexanone vapors have narcotic which have inhibitory effect on central nervous system. At the same time, cyclohexanone having a stimulating effect to skin and mucous membrane.  As we known, there are three method to make cyclohexanone. They are phenol method, cyclohexane oxidation mehod and hydrogenation of benzene oxidation method.

Phenol method usually use nickel as catalyst. Adding hydrogenation to the phenol, we can get cyclohexanol. Then using the zinc as catalyst to move the hydrogenation, so that we can get cyclohexanone. Cyclohexane oxidation method is always regarded cyclohexane as material and after a series of treatment, we will get qualified products.

High concentrations of cyclohexanone poisoning will damage the blood vessel and cause cardiac muscle, lung, liver, spleen, kidney and brain lesions. Even it may cause large coagulation necrosis. Then absorbed by skin. Finally there will be tremors anesthesia, reduce temperature and until to death. Cyclohexanone is widely used for coating producing, synthetic resin dissolved and preparing paint stripping agent. It also could be regarded as penicillin, tetracycline production solvent. Cyclohexanone is an important chemical raw material for a wide range of application. It is mainly used as intermediate of caprolactam, adipate acid and its salt.  It has good dissolving capacity, little poison and relatively low price.
