Abstract

The invention discloses a double-effect rotary evaporator. The double-effect rotary evaporator comprises a support frame, a distillation device and a condensation device; the condensation device comprises at least two spiral condensation pipes which are arranged in parallel; the supporting frame is provided with a clamping device; the spiral condensation pipes are arranged on the supporting framethrough the clamping device; one end of each spiral condensation pipe is connected with the distillation device through a multi-way connecting pipe; and the other end of each spiral condensation pipeis connected with a vacuum pump through a multi-way vacuum joint. According to the double-effect rotary evaporator, rotary distillation can be realized under a reduced pressure condition, condensationis carried out by adopting a plurality of spiral condensation pipes, and the purpose of quickly and efficiently recovering a solvent is achieved.

Description

technical field [0001] The invention relates to a vacuum distillation device, more specifically, it relates to a double-effect rotary evaporator. Background technique [0002] The current distillation technology includes molecular distillation technology and ordinary vacuum distillation and so on. The latter is a commonly used solvent recovery technology in laboratories. Due to the high boiling point of certain liquid organic compounds, when distillation is carried out under normal pressure, decomposition, oxidation and polymerization will often occur when the heating has not reached its boiling point, so it cannot be used under normal pressure. Distilled. The boiling point of some chemical solvents is related to the pressure applied to the surface of the liquid by the outside world. As the external pressure decreases, the boiling point of the liquid decreases. For these organic compounds, vacuum distillation can be carried out in a closed device, that is, under atmospheric...
