2-Ethoxynaphthalene Chemical Properties,Uses,Production
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 or light brown crystals (mp 37–38°C), with a mild, long-lasting, orange blossom fragrance. Soluble in 7 volumes of 95% ethanol and oily fragrances. Sweet orange blossom and grape notes at the very lightest stage, the aroma is more gentle and delicate, with a very long-lasting scent.
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 .
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
Not classified
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.]
