实验过程

In a 1000 ml eggplant-shaped flask, 14 g of 1-bromo-2-dodecanol was dissolved in 110 ml of acetone. A solution obtained in advance by dissolving 35 g of sodium dichromate dihydrate in 150 ml of distilled water and 25 ml of sulfuric acid was dropped thereto. These substances were stirred at room temperature for 1.5 hours, and then 250 ml of ether was added thereto. The resultant substance was dehydrated, and the solvent was removed. As a result, a white solid was obtained. The yield was 80%.
