A process for producing cyclohexenone long-chain alcohol represented by the following formula (1): (wherein A represents a C10-C18 alkylene or alkenylene group, and each of R
1
, R
2
, and R
3
individually represents hydrogen or methyl), comprising reacting a 3-alkoxy-2-cyclohexen-1-one derivative represented by the following formula (2): (wherein R
1
, R
2
, and R
3
have the same meanings as above, and R
4
represents a C1-C5 alkyl group) with a Grignard's reagent prepared by protecting the hydroxyl groups of C10-C18 ω-halogenoalcohol through silylation, and hydrolyzing the resultant reaction product. The process of the present invention for producing cyclohexenone long-chain alcohol requires a reduced number of reaction steps, can be performed with ease and with reduced production cost, and thus finds utility in the industry.
