Chemical Properties |
Methyl 2-Naphthyl Ether forms white crystals (mp 73–74°C) with an intense orange blossom odor. |
|
Uses |
2-Methoxynaphthalene is an Impurity of the non-steroidal anti-inflammatory Naproxen (N377525). |
|
Preparation |
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.] |
