The paper, Reductive and transitionmetalfree: oxidation of secondary alcohols by sodium hydride, by David Wang and colleagues of Peking University in Shenzen, China, described how the authors were attempting the standard preparation of the sodium alkoxide salt .
It was found that the catalytic performance is remarkably enhanced after using HRG as catalyst codopant for the aerobic oxidation of alcohols, possibly owing to the presence of carbon defects and ...
Ball mills are commonly used in the manufacture of Portland cement and finer grinding stages of mineral processing, one example being the Sepro tyre drive Grinding Mill. Industrial ball mills can be as large as m (28 ft) in diameter with a 22 MW motor, drawing approximately % of the total world''s power (see List of countries by ...
Oxidation Of Alcohols By Mno2 With Ball Mill. We are a largescale manufacturer specializing in producing various mining machines including different types of sand and gravel equipment, milling equipment, mineral processing equipment and building materials equipment.
Here, we demonstrate the use of lipase B from Candida antarctica (CALB) in acylative kinetic resolutions of secondary alcohols in mixer and planetary mills. Despite the mechanical stress caused by the high‐speed ball milling, the biocatalyst proved highly effective, stable, and, in part, recyclable under the applied mechanochemical conditions.

In mechanochemistry, reactions are performed by grinding the reaction mixture in ball mills, such as the vibrational ball mill or the planetary ball mill, or with a pestle and mortar. In preliminary studies, we tested a vibrational ball mill for photocatalytic oxidations with riboflavin tetraacetate, using a .
In situ ball milling of solid catalysts is a promising yet almost unexplored concept for boosting catalytic performance. The continuous preferential oxidation of CO (CO‐PROX) under in situ ball milling of Cu‐based catalysts such as Cu/Cr 2 O 3 is presented. At temperatures as low as −40 °C, considerable activity and more than 95 % selectivity were achieved.
