Description |
(β-Naphthyl ethyl ether has an odor suggestive of orange blossom with a faint, fruity undertone. It has a corresponding sweet taste suggestive of strawberry (on extreme dilution only). This substance may be prepared by esterification of P-naphthol with ethyl alcohol and sulfuric acid; from β-naphtholsodium and diethylsulfate in weak aqueous base; fromβ-naphtholsodium and ethyl bromide. |

Chemical Properties |
Ethyl 2-Naphthyl Ether forms white crystals (mp 37–38°C), with a mild, long-lasting, orange blossom fragrance. |
|
Preparation |
By esterification of β-naphthol with ethyl alcohol and sulfuric acid; from β-naphtholsodium and diethylsulfate in weak aqueous base; from β-naphtholsodium and ethyl bromide. |
|
Taste threshold values |
Taste characteristics at 4 ppm: powdery, floral, soapy and heavy with a berry and grape nuance. |
|
Purification Methods |
Crystallise it from pet ether or EtOH (m 37-38o). Dry it in vacuo, or distil it in a vacuum. The picrate has m 104.5o (from EtOH or CHCl3). [Beilstein 6 H 606, 6 II 578, 6 III 2972, 6 IV 4257.] |
