2) The flask is then clamped to the rotary evaporator and the equipment is turned on. The rotation is fixed to 100 rpm and keep constant throughout the experiment. 3) The temperature is set to 30⁰C. After the temperature is stabilized, the counting of time is started for fix time for 10 minutes. Then, the volume of the condensate is recorded.
