Beskrivelse |
β-Naphthyl methyl ether has an intensely sweet, floral odor suggestive of orange blossoms. It is free from naphthol by-odor. It has a sweet, strawberry taste. This may be prepared from potassium β-naphthol and methyl chloride at 300°C; by methylation of β-naphthol with dimethyl sulfate or by direct esterification with methyl alcohol. |

Kjemiske egenskaper |
Methyl 2-Naphthyl Ether forms white crystals (mp 73–74°C) with an intense orange blossom odor. |
Uses |
2-metoksynaftalen er en urenhet av det ikke-steroide antiinflammatoriske Naproxen (N377525). |
Forberedelse |
From postassium β-naphthol and methyl chloride at 300°C; by methylation of β-naphthlol with dimethyl sulfate or by direct esterification with methyl alcohol |
Purification Methods |
Fractionally distil the ether under vacuum. Crystallise it from absolute EtOH, aqueous EtOH, *C6H6, pet ether or n-heptane, and dry it under vacuum in an Abderhalden pistol or distil it in vacuo. The picrate has m 118o (from EtOH or CHCl3). [Kikuchi et al. J Phys Chem 91 574 1987, Beilstein 6 III 2969, 6 IV 4257.] |
