Ball milling is an effective green method for asymmetric organic synthesis...
Mechanochemistry using ball mills is a promising technology and has applications in organic chemistry, inorganic chemistry and materials science. In the process of ball milling, up to 80% of the energy generated in the mill is lost in the form of heat. This is why it is important to measure and control the temperature in the ball mill, for example, if a heat sensitive product is formed...

The ball mill yxqm-2l planetary ball mill of Changsha mitt instrument and equipment company was used for ball milling test. A total of 1.20g of the mixture of non-metallic particles and iron powder was placed in the grinding pot of an agate ball with a diameter of 510mm. The total weight of the ball is about 180 grams. Iron powder and nonmetal particles are milled together
Hydrogen hydrogen is a kind of environment-friendly energy, which only produces water by combustion. It is a useful reducing agent in organic matter. However, according to the law, the chemical must be strictly stored, transported and managed in the pressure vessel. Although hydrogen is mainly produced by steam reforming of methane and methane, it is not environmentally friendly due to the existence of methane and methane...
