An Orders‐of‐Magnitude Increase in the Rate of the Solid

Shaken, not stirred: CO oxidation was carried out continuously in a shaker ball mill.During milling, the reaction rate increases dramatically, but drops rapidly to zero when the mill is stopped. Compared to a conventional experiment in a plug‐flow reactor, the rate of a ball‐mill reaction catalyzed by Cr 2 O 3 is three orders of magnitude higher at room temperature and one order ofget price

In this reaction a small amount of S-diazocine is directly formed and a larger fraction of the azoxy compound is obtained, which can be reduced in a second syn-thetic step using lead in a ball mill. However, these reaction conditions are not suitable for functionalized S-diazocines due to poor yields and low reproducibility.get price

Ball mill Wikipedia

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. Tget price
