| | 1-PENTANOL, 3-METHYL-5-PHENYL Usage And Synthesis |
| Chemical Properties | 1-PENTANOL, 3-METHYL-5-PHENYL is a colorless liquid, bp0.013 kPa 86–91 °C, d20
20 0.960–0.964,
n20
D 1.511–1.514, with a long-lasting diffusive, fresh, floral, rose odor.The alcohol
is prepared by hydrogenation of tetrahydro-4-methylene-5-phenylpyran, which is
obtained by cyclocondensation of benzaldehydewith 3-methyl-3-buten-l-ol in the
presence of p-toluenesulfonic acid.
It can be used in all perfume types for a wide range of products, for example,
soaps, detergents, and body care products. | | Flammability and Explosibility | Nonflammable | | Trade name | Phenoxanol® (IFF), Phenylhexanol (Firmenich), Mefrosol
