Hazard Information | Back Directory | [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. | [Chemical Properties]
light brown crystals | [Chemical Properties]
β-Naphthyl ethyl ether has an odor suggestive of orange blossom with a faint, fruity undertone. Also, it has a corresponding sweet taste suggestive of strawberry (on extreme dilution only) | [Uses]
The fluorescence of 2-Ethoxynaphthalene has been shown to be weakly quenched by m-dimethlphthalate and methyl benzoate. Importantly, at increased concentration methyl benzoate enhances the fluorescence by increasing the polarity of the solvent . | [Application]
2-Ethoxynaphthalene is used in trace amounts in
flavor compositions, mainly in fruit complexes, berry compositions, Honey and Nut imitations, etc. In extreme dilution, the flavor is
mainly fruity, sweet and Grape-StrawberryIike. | [Definition]
ChEBI: 2-Ethoxynaphthalene is a member of naphthalenes. | [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. | [General Description]
Nerolin bromelia is an alkyl ether of 2-naphthol, which is generally used as a perfume and flavoring compound. | [Flammability and Explosibility]
Notclassified | [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.] |
