The MVD were performed with a lab scale MVD dryer (mWaveVac0150 1c, Püschner, Schwanewede, Germany). The system consisted of a vacuumvesselwith an integratedwall heater to avoid condensing vapor in the system. The vessel wall was adjusted to 50 C during the drying process. The dryer had a maximal microwave power of 1000Wproduced by 1.2kW/2450MHzmagnetron and amagnetron protection system. During the drying process, the pressure was decreased by a vacuum pump.
