Fractionating device and fractionating method for organic chemical experiment

Abstract

The invention discloses a fractionating device for an organic chemical experiment. The fractionating device comprises a pressure-resistant tank, a centrifugal pump, a stock solution storage tank, a resistor, a condenser and a buffer tank, a stock solution in the stock solution storage box enters the pressure-resistant tank through the centrifugal pump, the resistor is arranged at the bottom of thepressure-resistant tank and used for heating the stock solution in the pressure-resistant tank, the heated stock solution becomes steam and enters the condenser, and after heat exchange is repeatedlyconducted in the condenser pipe, fractions enter the buffer tank. The device solves the problems of complicated operation process and impure fraction components of the existing organic chemical experiment fractionating device. The invention discloses a fractionating method of a fractionating device for an organic chemical experiment, which can meet the requirements of fractionation of fractions with different boiling points, sampling and circulation in the flow division process and cleaning of a pressure-resistant tank, and is convenient to operate.

Description

technical field [0001] The invention belongs to the field of fractionation of organic matter, and relates to a fractionation device for organic chemistry experiments and a fractionation method thereof. Background technique [0002] The existing fractionation devices for organic chemistry experiments cannot fractionate large quantities of organic mixed solvents. The fractionation devices used in the laboratory are glass instruments, which may be broken during the experiment; on the other hand, there is a lack of effluent treatment devices. When the discharge port accumulates to a certain extent, it will cause the discharge port to be blocked, requiring staff to clean it regularly, and the use effect is poor. Contents of the invention [0003] The object of the present invention is to overcome the shortcoming of above-mentioned prior art, a kind of fractionation device and fractionation method thereof of organic chemistry experiment are provided. [0004] In order to achiev...
