What is solution distillation? Since x solvent in the solution is less than 1, the vapor pressure of the solvent in the solution is always lower than that of the pure solvent. Distillation curve of sucrose aqueous solution. Curve 1 and curve 2 represent the temperature-vapor pressure curves of water and sucrose aqueous solutions, respectively. The presence of sucrose molecules in the solution will reduce the concentration of water molecules on the surface of the solution, thereby reducing the vapor pressure of the solution. Therefore, the vapor pressure of the solution (point B) is lower than the vapor pressure of water (point A) at the same temperature. Water will boil at 100°C (under 1 atmosphere), but the solution will not boil yet. Only at a higher temperature (point B') the solution will boil. For this type of solution, distillation is either used to recover pure solvent or to obtain solid solute.

The difference in the volatility of each component in the liquid mixture is used to partially vaporize the liquid mixture and then partially condense the vapor, thereby achieving the separation of the components contained therein. It is a unit operation of mass transfer separation. It is widely used in oil refining, chemical industry, light industry and other fields.

Distillation can be divided into tower distillation and towerless distillation.Judging from the history of world distillation development, 3000-5000 years ago, there were separation and purification requirements in the production of alcohol. However, the content of long-term liquor is around 15-20 degrees. After countless inventors' research, prototype separation devices are available. The 42-56 degrees ethanol is a peak of purification, which is the current content range of liquor. More than 200 years ago, French inventors used distillation towers to produce 95% ethanol, which was a recognized record in the distillation industry. More than 30 years later, British inventors invented rectification towers based on distillation towers and produced With 99-99.9% ethanol, the word "alcohol" was produced for the first time, meaning the essence of wine. Methanol or ethanol production plants, lined with 20-120 meters high and 0.3--13.5 meters in diameter. Distillation [rectification] towers, with various structures, all derived from the products of French and British inventors. The largest distillation [rectification] tower The annual production can reach 50,000 to 300,000 tons, which is the main purification method for organic solvents.

Process of distillation

Distillation is a thermodynamic separation process, which uses the different boiling points of the components in the mixed liquid or liquid-solid system to evaporate the low-boiling components, and then condense to separate the entire components. There are two types of unit operations: evaporation and condensation. Union of unit operations. Compared with other separation methods, such as extraction, filtration and crystallization, its advantage is that it does not need to use other solvents other than system components, so as to ensure that no new impurities are introduced.

A distiller is an appliance that uses distillation to separate substances. Its shape consists of a round-bottomed distillation flask with a stopper and a serpentine condenser tube through frosting. The principle is to use the distillation method to gradually evaporate the mixture of different boiling points in the distillation flask, and continuously remove the generated vapor, and cool it in the condenser tube to achieve the purpose of separation and purification of the mixture. It is suitable for water quality analysis in water plants, epidemic prevention stations, laboratories of scientific research units, and fractionation and purification of various organic solvents.
