Description and Uses
DL-1-Phenethylalcohol has been identified as a volatile component of food (e.g., in tea aroma and mushrooms). The alcohol is a colorless liquid with a dry, rose-like odor, slightly reminiscent of hawthorn. It can be prepared by catalytic hydrogenation of acetophenone. 1- Phenylethyl alcohol is used in small quantities in perfumery and in larger amounts for the production of its esters, which are more important as fragrance materials.
The Arthrobacter sp. is able to grow with (+ I-,(-)-1-phenylethanol or the racemic mixture as sole source of carbon. Growth is most rapid with the (-)-isomer, doubling time 12 h. Lipases show good activity and, in some cases, improved enantioselectivity when employed in pure ionic liquids for dynamic kinetic resolution of 1-phenylethanol by transesterification.
