Today, I will bring you some explanations about the distillation principle of the double-layer glass reactor.
Double wall glass reactor working principle:
Distillation, many people know this term, but it is really specific to what is the principle of distillation and how does it work?
I believe that many people are not clear. Taking the separation of two-component mixtures as an example, the analysis was carried out. After the raw material liquid is heated, partial vaporization will occur, in which the volatile components will be concentrated in the steam, while the remaining liquid will produce higher non-volatile components, which achieves the separation of the two to a certain extent. . The greater the difference in volatilization between the two, the greater the concentration of the two substances. Using an industrial rectification device, the partially evaporated liquid phase is directly contacted with the partially condensed gas phase, thereby realizing partial evaporation of the liquid phase and partial condensation of the gas phase, that is, partial evaporation of the gas phase and partial condensation of the gas phase, so as to realize the partial evaporation of the gas phase and the partial condensation of the gas phase. Partial evaporation and partial condensation of the gas phase.
The molecules of the liquid tend to spill over the surface due to molecular motion. This trend increases with increasing temperature. When a liquid is placed in a closed vacuum system, the molecules of the liquid will continuously escape, forming a vapor on the surface of the liquid, after which the molecules will escape from the vapor, and then the molecules will escape from the vapor back into the liquid, and the vapor remains certain pressure. At this point in time, the liquid surface is saturated, which is called saturated vapor, and the pressure it exerts on the liquid surface is called the saturated vapor pressure. The results show that the saturated vapor pressure of the liquid is only related to the temperature, that is, the liquid has a certain vapor pressure at a certain temperature. Refers to the pressure under which a liquid is in equilibrium with its vapor, regardless of the amount of liquid and vapor in the system.
The combined operation of heating a liquid until it boils, turning it into a vapor, and then cooling the vapor and condensing it into a liquid is called distillation. Obviously, distillation can separate volatile and non-volatile substances, as well as mixed liquids with different boiling points. However, in order to obtain a good separation effect, the boiling points of the components of the mixture must be very different (at least 30°C or more). During atmospheric distillation, since the atmospheric pressure is usually not exactly 0.1MPa, strictly speaking, the boiling point plus the correction value should be observed, but since the deviation is usually small, even if the atmospheric pressure differs from the atmospheric pressure by 2.7KPa, the correction value is only ± 1°C, so it can be ignored.
