High speed ball milling hsbm

The as-prepared ZnAl2O4 nano-powders have been used as a catalyst on the synthesis of pyran nucleus using high-speed ball milling (HSBM) technique. The structure of products was confirmed with NMR analysis. Results: ZnAl2O4 exhibits a cubic crystal structure (Space group: Fd-3m) with the average crystallite size of 41 nm. The average particle

    Jun 01, 2015 High Speed Ball Milling (HSBM) process has been adapted to several well-known chemical reactions including alkene bond-forming reactions, and aryl-aryl cross-coupling reactions [20–21]. We hypothesized that a High Speed Ball Milling process applied to Ullmann cross-coupling reaction would be cost-effective if sufficiently activated haloarenes

    HSBM is an environmentally benign method by which reagents are placed inside a vessel along with a ball-bearing that is shaken at high speeds in the absence of solvent [21,22,23]. The high speed attained by the ball-bearing has enough force to make an amorphous mixture of the reagents which in turn facilitates a chemical reaction
