反应详情

A stirred mixture of 10.6 g of 1,2-epoxycyclohexanemethanol and 8 drops of concentrated sulfuric acid in 100 ml of p-dioxane and 100 ml of water was heated at 60°-70° for 18 hours. The reaction mixture was neutralized with sodium hydroxide, and evaporated under reduced pressure to a viscous residue. The residue was taken up in methanol and dried with sodium sulfate. The mixture was filtered and the filtrate evaporated under reduced pressure to a residue. The residue was distilled to give 10.8 g of 1,2-dihydroxycyclohexanemethanol; bp 170°-240°/0.02 mm. The nmr spectrum was consistent with the assigned structure.
