Method of synthesizing cyclohexanone

A method of synthesizing cyclohexanone comprises:

• oxidation of cyclohexane to produce a mixture including cyclohexanone, cyclohexanol, and cyclohexane;
• and
• separating the cyclohexanone from the mixture by contacting a first side of a pervaporation membrane with the mixture and receiving the cyclohexanone from a second side of the pervaporation membrane as a low pressure vapor,
• wherein the pervaporation membrane comprises poly(styrene-maleic anhydride-dihydropyrane).

A method of synthesizing a pervaporation membrane, comprising:

• dissolving maleic anhydride in acetone to form a first mixture;
• adding styrene to the first mixture to form a second mixture;
• adding 2,3-dihydro-4H-pyran to the second mixture to form a third mixture;
• heating the third mixture until a product is formed;
• cooling the product;
• dissolving the product in dimethylformamide to form a fourth mixture;
• and
• heating the fourth mixture to form the membrane.
