Abstract

Present invention is related to method for selective hydration of aroma olefins to alcohols in continuous solid catalyst column reactor. The invention discloses the continuous production of unsaturated aroma alcohol and/or ester comprising of C10-12 carbon chain by selective solid acid catalyzed hydration reaction. According to the process of the invention production of Octa-1-ene-7- ol, 3,7-dimethyl- (Dihydromyrcenol) and/or dihydromyrcenyl acetate can be carried out by passing 1,6-Octadiene, 3,7-dimethyl- (dihydromyrcene) and water continuously through a packed bed column reactor wherein the residence time of column is not more than 90 minutes and reaction temperature not substantially above 100 degree C. The present disclosure solves the problem of effluent treatment and increases the yield of the process due to selectivity in reaction.
