Ball milling a green technology for the preparation and

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 pre-treatment allowed reducing the milling time from 16 to 8 hours.
