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. |
