2-Ethoxynaphthalene Use and Manufacturing
It is derived from 2-naphthol etherified with ethanol in the presence of sulfuric acid. Dissolve 2-naphthol in absolute ethanol, add concentrated sulfuric acid dropwise, and heat to reflux for 10 hours. The reaction solution was poured into 5% sodium hydroxide solution, and off-white crystals were precipitated, filtered, washed with cold water to pH=7.5, and dried to obtain 2-ethoxynaphthalene. The yield was 96%. The crude product can be refined by vacuum distillation, collecting 138-140°C (1.6kPa) fractions. It can also be prepared by reacting diethyl sulfate or haloethane with 2-naphthol sodium salt.
