10-BroModecanoic acid cas 50530-12-6

10-Bromodecanoic acid production method(1) from 10-hydroxy capric acid and hydrogen bromide reaction derived. Hydrogen bromide and 10-hydroxydecanoic acid were mixed in glacial acetic acid at a weight ratio of 6: 1 and reacted at normal pressure for 16 hours at 90 ° C. The excess hydrogen bromide and solvent acetic acid are then recovered by distillation. (2) 10-hydroxy-capric acid and sodium bromide – sulfuric acid reaction, this method is similar to the previous method, but the hydrogen bromide preparation and bromination reactions were combined: The steps are as follows: 3: 1 ratio Ratio) 0.3mol of sodium bromide, 0.1mol of 10-hydroxy-decanoic acid and 100g of glacial acetic acid into a glass three-necked flask, stirring at room temperature, followed by dropwise addition of 80% (by volume) of sulfuric acid Molar ratio or high).
