NOVELTY - Preparing dibenzyl ether, comprises taking graphene oxide as a catalyst and benzyl alcohol as a raw material, reacting at 70-170 degrees C for 12-36 hours under normal pressure and heat preservation conditions, and performing post-treatment of the reaction solution after completing the reaction to obtain dibenzyl ether. USE - The method is useful for preparing dibenzyl ether. ADVANTAGE - The method: is environment friendly, and utilizes the catalyst with high catalytic activity and high selectivity, which selectively catalyzes the dehydration and etherification of benzyl alcohol to produce dibenzyl ether; does not adopt any solvent or metal during the reaction process, and adopts mild reaction condition; and produces the product, which is environment friendly based on the guaranteed conversion rate of benzyl alcohol and high selectivity of dibenzyl ether.
