| Application | used in organic synthesis, as solvent and flame retardant. As the antidote Dimercaprol and polyurethane foam, unsaturated polyester, phenolic, epoxy resin and polypropylene flame retardant product intermediates. |
| production method | is obtained by the addition of allyl alcohol and bromine. The propylene alcohol is added to the carbon tetrachloride solvent, bromination is carried out at 25-27 ℃ while bromine is added, and the mixture is incubated for 1H (at 50±2 ℃), then the carbon tetrachloride is distilled and recovered, and washed with water and sodium carbonate until the pH value is 7-8, drying, filtering clear, vacuum distillation, collection of 140-160 deg C (2.66kPa) fraction as a product. It is also possible to carry out the production without a solvent: The propylene alcohol is added to the reaction pot, and cooled with stirring. Bromine was added dropwise below 10 °c. The dropping acceleration is preferably such that the reaction temperature does not exceed 20 °c. After completion of the addition, the mixture was stirred at room temperature for 1.5h, water was added, and the mixture was stirred for 10min. The oil layer was separated and neutralized to neutral by adding sodium carbonate solution. After standing, the oil layer was separated and distilled under reduced pressure, the fraction at 115-125 ° C. (3.99-5.32kPa) was collected to obtain 2, 3-dibromo-1-propanol. |
