Abstract: PROBLEM TO BE SOLVED: To provide a method for producing corresponding aldehydes in high yield and selectivity by reacting a carboxylic acid or an ester thereof with hydrogen. SOLUTION: 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.

Abstract: Synthesis of aldehyde (I) involves reacting carboxylic acid (II) or its ester with hydrogen and water in gaseous phase, in the presence of a catalyst containing at least 60-99.9 weight% (wt.%) of zirconium oxide and 20 wt.% or less of lanthanides as catalyst active ingredients. Synthesis of aldehyde of formula (I) involves reacting carboxylic acid of formula (II) or its ester with hydrogen and water in the presence of a catalyst containing at least 60-99.9 wt.% of zirconium oxide and 20 wt.% or less of lanthanides as catalyst active ingredients. R , R , R , R = hydrogen, 1-6C alkyl, 3-8C cycloalkyl, aryl, 7-12C alkylphenyl or 7-12C phenylalkyl, preferably R , R together form 3-7C alicyclic ring, and preferably R , R = 1-4C alkoxy, phenoxy, methylamino, dimethylamino or halogen, more preferably R = hydroxy or amino.
