Likewise, formation of ophenyl and bithiophenyl products 3f and 3g can be improved to 34% and 83% yield, respectively, after just 30 min of ballmilling at 40 Hz with 1 and silica gel, while the reaction without silica gel would barely give any DCR products (<5% yield) under the same milling condition.
A wide variety of silica grinding ball mill options are available to you, such as 5 years. You can also choose from energy mining, construction works, and building material shops silica grinding ball mill, as well as from 1 year silica grinding ball mill, and whether silica grinding ball mill is ac motor, or dc motor.

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].
