Production method | Bromination of tetrahydrofuran methanol. Benzene and phosphorus tribromide are added to the reaction pot, stirred and cooled to about 0 ℃, the mixed solution of tetrahydrofuran methanol and pyridine is evenly added dropwise, stirred for 1h, and heated to 20 ℃ for 1h. Leave overnight, distillation under reduced pressure, and collect the 55-130 ℃(2.67kPa) fraction to obtain tetrahydrofuran methyl bromide. |
