  • and solvent free Sonogashira coupling in a ball mill RSC Publishing

    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(PPh3)4 in combination with 1,4 diazabicyclo[2.2.2]octane (DABCO) were chosen as catalysts and base, respectively. The reaction was investigated us.

  • Effect of Milling Environment on the Breakage Rates in Dry and Wet

    In ball milling the rates of breakage vary primarily with the size distribution of powder in the mill. Using an limestone and copper ore show time dependent breakage rates under both dry and wet grinding conditions. The effect of In the formulation of the size discretized model for batch ball mills, the particulate assembly.
