What is the configuration method of 2-Bromo-1-phenyl-1-pentanone CAS: 49851-31-2?

At room temperature, add 16.2 g (0.1 mol) of valerophenone and 30.9 g (0.3 mol) of sodium bromide to a 500 mL round-bottomed flask and stir well, then add 24 g (0.2 mol) of 30% hydrochloric acid, and slowly dropwise add 19g

(0.15mol) 30% hydrogen peroxide, after adding dropwise to the end of Chemicalbook, continue the reaction for 1~2h, after the TLC monitoring reaction is over, stop stirring, let stand for stratification, and use saturated sodium carbonate and saturated brine respectively.

After washing, the organic phases were combined, concentrated and dried over anhydrous magnesium sulfate to obtain 2-Bromo-1-phenyl-1-pentanone CAS: 49851-31-2, a bright yellow oily liquid with a yield of 95% and a purity of 98% (HPLC method).

What does Bromovalerophenone do?

Bromovalerophenone is a dry powder solid, which is a mixture of acid salts and surfactants. They have a wide range of uses, are easily soluble in water, can replace traditional triacids and hydrofluoric acids, and can remove rust and lamp welding slag on various metal surfaces in a targeted manner. Can be used to play a special activation effect.

During the rise of the electroplating industry, Bromovalerophenone also led to the development of acid salts, producing acid salts for electroplating of different metals, such as aluminates, iron aluminates, zincates, and tantalates. my country's acid salt industry has also developed rapidly. Since the reform and development, a number of enterprises that develop and produce acid salts have emerged.

Such as matt environmental protection, the KC-615 acid salt produced by it is specially designed for the activation of nickel, iron, copper alloy and zinc alloy parts, as well as the rust and oxide film removal of iron parts, and the surface treatment of zinc aluminum alloy before passivation. Product effect is high quality.

Bromovalerophenone should pay attention to the fact that the steam of this product can form an explosive mixture with air, which can cause combustion and explosion in case of open flame and high heat energy; it can react with oxidants; the flow rate is too fast, and it is easy to generate and accumulate static electricity; If it is too hot, the pressure inside the container will increase, and there is a danger of cracking and explosion.
