Abstract

The invention discloses a perfluoropolyether functional intermediate purification device which comprises a base, a bearing box, a lifting mechanism, a second valve, a motor and an air exhaust and cleaning mechanism; wherein the bottom of the bearing box penetrates through a first bearing frame to be in threaded connection with a fastener, a heating plate is arranged on the inner side of an electric heater, and the lifting mechanism is fixed to a second bearing frame; a feeding channel is fixed to the top of the top cover, the second valve penetrates through the top cover to be connected with the bottom of the feeding channel, the bottom of the feeding channel is rotationally connected with a stirring column, and the air exhausting and cleaning mechanism is fixed to the left side and the right side of the top of the top cover. According to the perfluoropolyether functional intermediate purification device, before the device is used, a connecting hose and an external air pump need to beconnected together through a connector, and a perfluoropolyether functional intermediate is obtained after raw materials and auxiliaries fully react; after the power of an electric heater is increased, the temperature of a heating plate is increased, and thereby small molecular impurities can be volatilized into gas to be separated from perfluoropolyether after being in contact with the heating plate.

Description

technical field [0001] The invention relates to the technical field related to the preparation of perfluoropolyether, in particular to a purification device for perfluoropolyether functional intermediates. Background technique [0002] Perfluoropolyether is a synthetic polymer that is liquid at room temperature. It has been used as a lubricant for aerospace mechanical components for decades. The functional intermediate of perfluoropolyether can be obtained by reacting perfluoropolyether with additives. After the perfluoropolyether functional intermediate is obtained, there are still small molecular impurities such as solvents and reactants in the perfluoropolyether functional intermediate. Due to the high viscosity of the product, it is difficult to completely remove the small molecules mixed in it by ordinary operation methods. Impurities, in order to obtain more pure perfluoropolyether functional intermediates, it is necessary to use a separator to separate small molecular...
