| 4-Bromo-1-butanol Usage And Synthesis |
| Description | 4-Bromo-1-butanol can be prepared by azeotropic distillation of butane-1,4-diol with 47% HBr with a yield of about 65%.1 4-Bromo-1-butanol can be used to prepare 2-(4-bromo-butoxy)-tetrahydro-pyran by reacting with 3,4-dihydro-2H-pyran in the presence of amberlyst 15 and the menstruum hexane.1 It reacts with dihydropyran to prepare tetrahydropyranyl ethers.2 |
| Chemical Properties | Clear colorless to brown liquid |
| Uses | 4-Bromo-1-butanol is used to prepare 2-(4-bromo-butoxy)-tetrahydro-pyran by reacting with 3,4-dihydro-2H-pyran in the presence of amberlyst 15 as a catalyst. It reacts with dihydropyran to prepare tetrahydropyranyl ethers. |
