When the system device is used, firstly, a mathematical model of the saturated steam pressure and the saturated steam temperature of the solution is established based on the relationship between the saturated temperature and the saturated pressure of the solution, and p=f (t) and t=f' (p). Then, the vapor pressure data or the vapor temperature data of the solvent in the distillation device of the rotary evaporator 1, the bath liquid temperature data of the rotary evaporator 1 or the heat carrier temperature data and the secondary refrigerant temperature data for providing a heat source for the reaction kettle are continuously collected in real time through the negative pressure detection sensor 3.2, the vapor temperature detection sensor 1.1, the bath liquid temperature detection sensor 1.2 and the secondary refrigerant temperature detection sensor 2.3, and the collected data are uploaded to the singlechip controller 4.
