    摘要: A benzyl vinyl ether represented by the following formula is hydrolyzed in the presence of a catalyst selected among Arrhenius acids and Lewis acids to obtain 3,3,3-trifluoropropionaldehyde. Subsequently, the 3,3,3-trifluoropropionaldehyde is oxidized with an oxidizing agent. Thus, 3,3,3-trifluoropropionic acid can be more advantageously produced than in conventional techniques from an inexpensive starting material.
