Solvent 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.

In the process of preparation, a suitable solvent for the reaction is very important. We can see from the data in Table 1-1, the methanol is the best solvent for reaction.

1-1 Effect of different solvents on the yield of cyclohexanone

1-2 Effect of the amount methanol on the yield cyclohexanone

Table 1-1 shows that methanol is the best solvent for the reaction. As we can see from the data in Table 1-2, the yield of cyclohexanone decreases with increasing amount of methanol. Due to the increased amount of methanol, this results the concentration of reactants and the cyclohexanol conversion rate reducing.
