Abstract
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.
Claims7
A process for producing 3,3,3-trifluoropropionic acid represented by formula [3]
- comprising the steps of:
- hydrolyzing benzyl vinyl ether represented by formula [1]
- where R is one of a phenyl group and a phenyl group having a substitution group represented by R1, where R1 is a group selected from alkyl group, alkoxy group, halogen atom and nitro group, in the presence of a catalyst selected from Arrhenius acids and Lewis acids, thereby obtaining 3,3,3-trifluoropropionaldehyde represented by formula [2]
- and
- oxidizing the 3,3,3-trifluoropropionaldehyde with an oxidizing agent.
