Abstract
The utility model discloses a decompression and distillation device for removing a high boiling point solvent in a microreaction. Glass apparatuses used by the device comprise a tail splice tube, a condensation tube, a buffer ball and a round-bottom flask which are subjected to socket connection end to end from top to bottom, the lower most side of the device is also provided with a reaction heating device, and a vacuum pump is connected with a branch tube of the tail splice tube through a pipeline, wherein all the apparatuses are fixed on a bracket respectively through fixing clamps. The decompression and distillation device has the advantages that the device is vertically arranged, so that the occupation space is greatly reduced, the number of students capable of participating in an experiment each class can be increased by one time, and the teaching efficiency is greatly improved; and in addition, the spherical part of the buffer ball is adopted as a container for collecting the high boiling point solvent for the first time, so that the high boiling point solvent in the microreaction not only can be removed, but also the adsorption of a product in the container cannot be caused so as to reduce product loss in an operating system.
Description
Technical field
The utility model relates to a kind of vacuum distillation apparatus of removing high boiling solvent in the micro-reaction.
Background technology
The boiling point of liquid is that the variation with ambient pressure changes, if reduce system's internal pressure by means of vavuum pump, just can reduce the boiling point of liquid, the basic theories that decompression distillation that Here it is operates.Decompression distillation is to separate one of the common method of organic compound of can purifying, and this method often can be used in college chemical experiment.Especially sometimes need the high boiling solvent in the organic reaction is removed, this method can be convenient.But in the past when carrying out this operation, used instrument all is that level is to being arranged on the experimental bench, can take larger space like this, when arranging the student to carry out education experiment, the instrument tricks that can put on the experimental bench will be seldom, the number of student that every class can be participated in the experiment also can be restricted, thereby has reduced efficiency of teaching.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of vacuum distillation apparatus of removing high boiling solvent in the micro-reaction, and it is few that this device has required instrument, and very little advantage takes up room.
The technical solution of the utility model is: this installs employed glass apparatus tail adapter, condenser pipe, buffering ball and round-bottomed flask, above-mentioned instrument from the bottom to top head and the tail socket joint joins, consist of the vacuum distillation apparatus of vertical setting, the below of this device also is provided with heating and stirring device, the arm that vavuum pump is taken over by pipeline and tail is connected, and above-mentioned each instrument is fixed on the support by stationary fixture respectively.
Advantage of the present utility model at first is to have adopted vertical setting by this covering device, takes up room thereby reduced widely, and the number of student that every class can be participated in the experiment can double, and has improved widely efficiency of teaching.In addition, adopt first the ball-type part of buffering ball as collecting high boiling container, this method both can be removed high boiling solvent in the micro-reaction, can not cause again the absorption of product in container, thereby reduce product loss in the operation system.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
Fig. 1 is structural representation of the present utility model.
Number in the figure:
1, tail adapter 2, condenser pipe 3, buffering ball 4, round-bottomed flask 5, arm 6, support
7, heating and stirring device.
The specific embodiment
Embodiment
As shown in Figure 1, this installs employed glass apparatus that tail takes over 1, condenser pipe 2, buffering ball 3 and round-bottomed flask 4, and above-mentioned instrument from the bottom to top head and the tail socket joint joins and consists of the vacuum distillation apparatus of the vertical setting of a cover.The below of this device also is provided with heating and stirring device 7, and vavuum pump is connected by the arm 5 of pipeline with tail adapter 1.Above-mentioned each instrument is fixed on the support 6 by stationary fixture respectively.
The operation principle of said apparatus is: by being connected to tail adapter place vavuum pump whole device is realized decompression, after round-bottomed flask is heated, high boiling solvent is under the condition of decompression, at a lower temperature boiling forms steam, enter in the condenser pipe along the aperture on the buffering ball, through the cooling effect of condenser pipe outer tube, steam is condensed and becomes condensate liquid, enter into the ball-type part of buffering ball, thereby finish the process of the high boiling solvent of decompression distillation.
Claims (1)
