| titleOfInvention | Production method of aromatic aldehyde |
| abstract | (57) [Summary] The method is based on the general formula (I) wherein R 1 , R 2 , R 3 , R 4 and R 5 are hydrogen, C 1 -C 6 -alkyl, C 3 -C 8 -cycloalkyl, aryl group, hydroxyl group, C 1 -C 4 - alkoxy group, a phenoxy group, C 7 -C 12 - alkylphenyl group, C 7 -C 12 - phenylalkyl group, amino group, methylamino group, dimethylamino group, or a halogen atom And R 1 may represent a formyl group or a COOR 6 group, and R 6 is a hydrogen atom, a C 1 -C 6 -alkyl group, a C 3 -C 8 -cycloalkyl group, an aryl group, a C 7 -C 6 -alkyl group. C 12 - alkyl phenyl group or C 7 -C 12 - discloses the preparation of aromatic aldehydes represented by a phenyl group]. For this purpose, the compounds of the general formula (II) in which R 1 , R 2 , R 3 , R 4 , R 5 and R 6 have the abovementioned meanings or R 2 , R 3 , R 4 and R 5 has the above-mentioned meaning and R 6 and R 1 together form a —CH 2 — bridge] At 450 DEG C. and 0.1-20 bar, in the presence of a catalyst whose catalytically active substance contains 80-99.9% by weight of zirconium oxide and 0.1-20% by weight of one or more lanthanide elements. To react. |
