Abstract

The present invention relates to a process for preparing 4-isopropylcyclohexylmethanol (IPCHM) from para-cymene. The process for preparing 4-isopropylcyclohexylmethanol (IPCHM) comprises an electrochemical process for preparing a mixture of 4-isopropylbenzaldehyde dimethyl acetal and 4-(1-alkoxy-1-methylethyl)benzaldehyde dimethyl acetal, and intermediates passed through in the process, a hydrolysis step to form the corresponding benzaldehydes and a hydrogenation of this mixture to form 4-isopropylcyclohexylmethanol (IPCHM).
