Basic information | Also known as α-methoxynaphthalene, and 2-methoxynaphthalene (β-methoxynaphthalene) are the isomers of methoxynaphthalene. Colorless crystals. It has an aroma, but not as good as 2-methoxynaphthalene. Relative density 1.0964 (14 ℃). Boiling point 269 ℃, 135 ℃(1 ∶ 333 × 103Pa). 1.6940 refractive index. Insoluble in water, soluble in ethanol, ether, benzene and chloroform. 1-Naphthyl ether, also known as 1-methoxynaphthalene and α-methoxynaphthalene, is an organic intermediate, which can be obtained by methylation of 1-naphthol. Methylation reagents can be selected from trifluoroacetate Methyl ester, dimethyl carbonate and dimethyl sulfate. |
use | 1-methoxynaphthalene is used to study the activity of cytochrome c peroxidase. As a precursor to synthesize isoamyl naphthyl alcohol, with antioxidant activity. Mainly used as film developer. Organic synthesis, insecticides, spices for making soap Used as dye intermediates, spices, due to the weak aroma of 1-methoxynaphthalene, mostly 2-methoxynaphthalene. |
preparation method | α-naphthol and methanol are used as raw materials, ferric chloride is used as catalyst, heated and refluxed to generate crude 1-methoxynaphthalene, After cooling, the organic phase is separated, or benzene is used to extract, the extraction layer is separated, then decompressed, cooled and crystallized, filtered, washed and dried with cold water, and recrystallized in ether, or sublimation refining, you can get refined 1-methoxynaphthalene. |
