Introduction:
The experiment was an oxidation of an alcohol to a ketone. Household bleach was used as a witnesser of sodium hypochlorite that was 5.25 % (0.75 M) aqueous tooth root of sodium hypochlorite; NaOCl (aq), an oxidizing agent to change cyclohexanolinto cyclohexanone. Bleach solution was added to a mixture of cyclohexanol and acetic acid. The yields are known better in acidic rather than introductory conditions. Therefore, acetic acid was used for this experiment. It reacted with the sodium hypochlorite to give hypochlorous acid, which thenreacted with the group O of the alcohol. Steam distillation was used to isolated product, and then was extracted into the distillation with ethyl ether with the addition of dying agent calcium chloride. Finally, the ether was removed to get the product, cyclohexanone with the salt out process. The process of salting out was used to separate cyclohexanone from the aqueous solution to purify the product. Which are weak intermolecular forces (e.g., hydrogen bonds) between entire molecules or nonelectrolytes and water are easily disrupted by the hydration of electrolytes.

Oxidation of Cyclohexanol
Mechanism of Oxidation
Cyclohexanolis an irritant. Avoid contact with skin, eyes, and clothing.
Acetic acid is a dehydrating agent, an irritant, and causes burns. When dispense these should be under a fume lummox or way fromthe bodyand avoid contact with skin, eyes, and clothing.
Sodium hypochlorite solution emits chlorine gas, which is a respiratory and
eye irritant.
Procedure:
To 250 ml Erlenmeyer flask, placed 8 ml (0.075 mol) of cyclohexanol in it; And the thermometer was placed a secure on the neck of the...If you want to get a full essay, order it on our website: Ordercustompaper.com
