1122-54-9, A common compound: 1122-54-9, name is 4-Acetylpyridine,molecular formula is C7H7NO, it can change the direction of chemical reaction, and react with certain compounds to generate new functional products. A new synthetic method of this compound is introduced below.
Preparation of 4-Bromoacetylpyridine, HBr saltHBrBromine (24 g, 150 mmol) in 4 mL of 45% HBr was added drop wise under vigorous stirring to a solution at 70C of 4-acetyl-pyridine (18 g, 148 mmol) in acetic acid containing 45% of HBr (165 mL). The vigorously stirred mixture was kept at 700C for 3h. The mixture was cooled and the precipitate collected by filtration and washed with petroleum ether(40-65C)/methanol (1/1, 100 mL) to give 35.8 g of a white crystals of (85%).
With the rapid development of chemical substances, we look forward to future research findings about 1122-54-9.
