Fractional distillation is one of the common methods for purifying and separating substances in chemical experiments, and is a process of heating a certain mixture, and cooling and separating the mixture into relatively pure single substances according to different boiling points of each component in the mixture. The fractionating device commonly used in the laboratory is a thorn-shaped fractionating column, a group of thorn-shaped glass columns which incline downwards are arranged in the column at certain intervals, and each group of thorn-shaped glass columns are arranged in a fractionating tube in a spiral shape.
When the boiling mixed vapor passes through the fractionating column, the boiling mixed vapor can exchange heat with cold air outside the column, because of the cooling of the cooled air, the components with high boiling point in the vapor are cooled into liquid and flow back to the reaction flask, so that the components with low boiling point in the rising vapor are relatively increased, when the condensate flows back to the flow diagram, the components with high boiling point in the vapor exchange heat with the rising vapor, the components with low boiling point in the vapor are condensed and flow back to the reaction flask, the components with low boiling point continuously rise, and the processes of vaporization, condensation, reflux and the like are repeatedly carried out in the fractionating column, and finally the vapor coming out from the top of the fractionating column is basically the components with low boiling point.
At present, a common thorn-shaped fractionating column utilizes air for condensation, when the temperature of the external environment is higher, the condensation effect of the fractionating column is lower due to high air temperature, and the fractionation effect cannot be effectively achieved by air condensation. When the temperature of the external air is too low, the temperature of the air is too low, and the column length of the thorn-shaped fractionating column is longer, so that steam can be quickly condensed in the rising process, flows back into the distillation flask, and sometimes is difficult to rise to the top end of the fractionating column and be distilled out. In order to solve the problem, cotton is wound on the outer wall of the fractionating column for heat preservation so as to enable steam to rise, but the cotton is inconvenient to wind and limited in heat preservation capability, and the cotton is easy to fall off, so that potential safety hazards are easy to bring. If the mixed liquid to be fractionated contains powdery solid impurities, the mixed liquid may be distilled out of the fractionating column along with low-boiling-point components during the fractionation process to influence the purity of the low-boiling-point components, therefore, a screen is often used for filtration, but the screen filters the distilled and condensed liquid, and a water film is easily formed on meshes of the filter screen due to the action of the liquid surface tension, so that the distilled components are prevented from entering the thorn-shaped fractionating column, the condensed liquid is also prevented from smoothly flowing into a distillation flask at the lower part of the thorn-shaped fractionating column, and the normal operation of an experiment is influenced.
