Prepartion of 4-isopropylcyclohexylmethanol and its alkyl ethers

摘要

4-isopropylcyclohexylmethanol and its alkyl ethers of the general formula I <IMAGE> (I) where R1 is H or C1-C4-alkyl, are prepared by a process in which the novel 4-(1-alkoxy-1-methylethyl)-benzaldehyde or its dialkyl acetal of the general formula II <IMAGE> (II) where X is oxygen (IIa) or its two R2O groups (IIb) and R2 and R3 are each C1-C4-alkyl, is heated to 100 DEG -250 DEG C., preferably 130 DEG -200 DEG C., under a hydrogen pressure of from 50 to 350, preferably from 150 to 300, bar in the presence of a noble metal of group VIII of the Periodic Table.
