1-Methoxynaphthalene Usage And Synthesis

Chemical Properties

clear light yellow to brown liquid

Uses

Perfumery (soaps).

Synthesis Reference(s)

Tetrahedron Letters, 32, p. 675, 1991 DOI: 10.1016/S0040-4039(00)74857-X

Purification Methods

Steam distil the ether from alkaline solution. The distillate is extracted with Et2O. After drying (MgSO4) the extract and evaporating Et2O, the methyl naphthyl ether is then fractionated under reduced pressure from CaH2. The picrate has m 129.5-130.5o (from EtOH). [Beilstein 6 IV 4211.]
