Beschreibung
Zusammenfassung:	The invention discloses a distillation device for synthesizing hexamethylphosphoramide. According to the invention, a filter of a feeding assembly communicates with a first valve, a first distillationshell of a distillation assembly communicates with the first valve, a first heater is installed on one side of the first distillation shell, a second distillation shell communicates with the first distillation shell, a second heater and a heat dissipation plate are installed in the second distillation shell, a first condensation pipe and a second condensation pipe of a condensation assembly are placed in a condensation box and communicate with the first distillation shell and the second distillation shell correspondingly, and a recovery pipe of a recovery assembly communicates with the firstdistillation shell through a second valve and the second distillation shell. According to the invention, by arranging the two distillation shells, rapid heating to an evaporation temperature in the first distillation shell can
