Description of β-naphthyl ether
- β-Naphthol methyl ether, also called 2-methoxynaphthalene or yara yara, is a stabilizer found in gunpowder, particularly smokeless gunpowders. It is soluble in alcohol, and insoluble in water and dipropylene glycol.
Studies have also been done on the antiinflammatory effect of β-naphthol methyl ether and on how it behaves in time-resolved resonance Raman studies.

What is 2-Methoxynaphthalene?
- With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is 2-Methoxynaphthalene which has developed particularly rapidly in recent years. Do you know about 2-Methoxynaphthalene?

What’s the application of 2-Methoxynaphthalene?
- It is used in low-grade colored soaps, detergents, and daily fragrances, and the suitable fragrance types are orange blossom, jasmine, and lily. Also used in low-grade cologne and floral essence can give a heavy floral fragrance. It can also be used in the fragrance of plastic products that need alkali resistance and heat resistance, and synthetic rubber products fragrance. 2-Methoxynaphthalene is an intermediate of organic synthesis, acetylation with ethyl anhydride in the presence of aluminum trichloride can be obtained 6-methoxy-2-naphthalene acetophenone. Nitrobenzene and 2-methoxynaphthalene into the reaction pot, at 5 ℃ slowly into aluminum trichloride (temperature water over 15 ℃) stirring 1h after cooling to 5 ℃, slowly add acetic anhydride, and then gradually increase the temperature, at 70-80 ℃ reaction nearly 2h, cold to below 30 ℃, add 1:1 hydrochloric acid solution, stirring and then divided to remove the water layer. Wash the oil layer with water to remove inorganic salts, then distill with water to remove nitrobenzene, extract with petroleum ether, concentrate, cool, crystallize and filter the extract to obtain 6-methoxy-2-naphthalene acetophenone with a yield of 50%. This is a pharmaceutical intermediate, used in the production of anti-inflammatory and analgesic naproxen. 2-Methoxynaphthalene is also used in the production of trenbolone and the family planning drug 18-methylethylenolone.
