by oxidation decarboxylation at 300-400. Oxidizing a primary alcohol can produce carboxylic acids. In this experiment‚ an aromatic carboxylic acids namely benzoic acid will be prepared by oxidizing benzyl alcohol‚ which is an aromatic alcohol with the formula. Benzyl alcohol is produced naturally by many plants and is commonly found in fruits and teas. The oxidizing agent used is alkaline potassium permanganate (VII).

The main product is trans-2-butene‚ because it is the most stable compound. However‚ the result of dehydration of primary alcohol is not expected. It is supposed to form only one product‚ 1-butene
