Definition
ChEBI: Phenylpropanol is an organic molecular entity.
Vorbereitung Methode
1-Phenyl-1-propanol is very rarely used in perfumes, but could find some application as a modifier for Phenylpropylalcohol in Hyacinth, Rose, Lilac, Magnolia, etc.
It finds some use in flavor compositions, almost exclusively in imitation Honey and in various fruit complexes. The concentration used is normally as low as 0.5 to 2 ppm in the finished product.
synthetische
By hydrogenation of phenethyl ketone.

Allgemeine Beschreibung
1-Phenyl-1-propanol enantiomers (E-PP) forms the inclusion complexes of cyclic decapeptide (CDP) which were studied using the density functional theory (DFT) B3LYP method. It was also used to determine the mass transfer kinetics effect on the elution profiles of the 1-phenyl-1-propanol (PP) enantiomers on Chiracel OB (cellulose tribenzoate coated on silica gel).
