Production method	It is obtained by reacting isopropanol with hydrobromic acid. Slowly add isopropanol to concentrated sulfuric acid while cooling, controlling the temperature below 30 ℃. After adding, add hydrobromic acid, slowly heat and reflux for 4 hours, then distill until oil droplets appear. Wash the crude product with concentrated sulfuric acid, water, and 5% sodium carbonate, then dry, filter, and fractionate with anhydrous sodium carbonate. Collect the 58.5-60.5 ℃ fraction to obtain the finished product. In addition, there is also the isopropanol sodium bromide method.
