Temperature Influencing Tungsten Trioxide Preparing Cyclohexanone

Cyclohexanone is organic compound, it is carbonyl carbon atom including the six-membered ring saturated cyclic ketone; it is colorless and transparent liquid, it containing traces of phenol. Cyclohexanone impurities are yellow. Cyclohexanone has a carcinogenic effect; it is mainly used in industrial organic synthesis of raw materials and solvents. Cyclohexanone is an important chemical raw materials, it is widely used in nylon, caprolactam and adipic acid intermediate principal. It is also an important industrial solvent, such as for paints, in particular for nitrocellulose, vinyl chloride polymers and copolymers or methacrylic acid ester polymer paint.

Tungsten trioxide catalytic preparing cyclohexanone are affected by many factors. We analyze them by the table in order to have further investigations on the effects for different polymorphs WO₃ catalyst preparing cyclohexanone yield:

As we can see from the table above, catalyst WO₃ form is changing with calcination temperature,, but the change of the cyclohexanone yield is not obvious, which can describe the reaction of crystalline WO₃ has little effect.
