Title:

SYNTHESIS OF ALDEHYDE

Document Type and Number:

Japanese Patent JP2002012571

Kind Code:

A

Abstract:

To provide a method for producing corresponding aldehydes in high yield and selectivity by reacting a carboxylic acid or an ester thereof with hydrogen.

This method for synthesizing the aldehyde of general formula I [R1 to R3 are each hydrogen, a 1-6C alkyl, a 3-8C cycloalkyl, an aryl, a 7-12C alkylphenyl or a 7-12C phenylalkyl, or R1 and R2 may form a 3- to 7-membered alicyclic ring by bonding to each other] comprises reacting the carboxylic acid or the ester thereof, represented by general formula II [R1 to R3 are same as the above; R4 is hydrogen, a 1-6C alkyl, a 3-8C cycloalkyl, an aryl, a 7-12C alkylphenyl or a 7-12C phenylalkyl] with the hydrogen in a vapor phase in the presence of a catalyst containing zirconium oxide and one or more kinds of lanthanoid elements in the presence of water.
