The esterification reaction was then performed in a planetary ball mill at 200 rpm using hexanoyl chloride as an esterifying agent. This process was performed including a 10 minutes cooling time every 20 minutes of milling. Compared to the previously reported method, the water pretreatment allowed reducing the milling time from 16 to 8 hours.

During the last decade numerous protocols have been published using the method of ball milling for synthesis all over the field of organic chemistry. However, compared to other methods leaving their marks on the road to sustainable synthesis ( microwave, ultrasound, ionic liquids) chemistry in ball mills is rather underrepresented in the knowledge of organic chemists.

For the so called G5 planetary ball mill, the maximum kinetic energy can reach J/hit ( J/hit for the G7 device), for a disc and vial rotation speeds respectively equal to 3. ... Figure 3 [15] illustrates the dynamically end product phase diagram which is mapped into three regions as a function of the shock power; a first corresponding to ...
This study was designed to examine the physical disintegration of graphene (GN), an excellent heat conductor, by using the planetary ball mill, a simple and convenient means to produce particles arbitrarily. The conditions for the disintegration of GN were distinguished by the rotation of the planetary ball mill (200 rpm, 400 rpm, and 600 rpm) and by the duration of its operation (30 min, 60 ...
