Abstract aryl chlorides and bromides are formed from arenes in a ball mill using khso 5 and nax (x = cl, br) as oxidant and halogen source, respectively. investigation of the reaction parameters identified operating frequency, milling time, and the number of milling balls as the main influencing variables, as these determine the amount of.
Abstract. ball mills 5.5 m (18 ft) in diameter and larger tend to use energy delivered to the mill less efficiently than smaller diameter mills, particularly when the large mills carry 40% by volume ball charges. this paper will explore factors used in scaling up ball mills, showing where the advantages of one factor can possibly be negated by.
