BENZYL ALCOHOL (C7H8O)
Benzyl alcohol is typically manufactured through the alkylation of toluene or benzaldehyde with sodium/potassium hydroxide or sodium/potassium benzylate in the presence of an alkylation catalyst. This reaction forms benzyl alcohol as the primary product, along with small amounts of by-products such as benzyl chloride and benzalphenone. Another method involves the reduction of benzyl chloride or benzotrichloride using hydrogen gas in the presence of a metal catalyst such as palladium or platinum.
