    Infobox referencesBenzyl alcohol is an organic compound with the formula C6H5CH2OH. The benzyl group is often abbreviated "Bn", thus benzyl alcohol is denoted as BnOH. Benzyl alcohol is a colorless liquid with a mild pleasant aromatic odor. It is a useful solvent due to its polarity, low toxicity, and low vapor pressure. Benzyl alcohol is partially soluble in water (4 g/100 mL) and completely miscible in alcohols and ether. It is prepared by the hydrolysis of benzyl chloride using sodium hydroxide:
    C6H5CH2Cl + NaOH → C6H5CH2OH + NaCl It can also be prepared via a Grignard reaction by reacting phenylmagnesium bromide (C6H5MgBr) with formaldehyde, followed by acidification. Like most alcohols, it reacts with carboxylic acids to form esters. Benzyl alcohol is produced naturally by many plants and is commonly found in fruits and teas. It is also found in a


    variety of essential oils including jasmine,
