The material of the steel ball is ZGMn13, and the selected mill rotation rate is 65%. 4.1 Particle Model Establishment

A solvent-free method for the Sonogashira coupling reaction was established under ball milling conditions without the use of copper or additional ligands. Pd(OAc) 2 or Pd(PPh 3) 4 in combination with 1,4-diazabicyclo[2.2.2]octane (DABCO) were chosen as catalysts and base, respectively. The reaction was investigated using a variety of aryl halides and acetylenes and …

When the ball mill rotates, the liner hits the grinding cylinder of the ball mill. Judge the position of the liner of the ball mill according to the sound, find out the loose bolts and tighten them separately. 2. The temperature of the bearings of the ball mill and the motor has risen, exceeding the requirements. Try to feel the bearing by hand.
