1. The 2l short path distillation kit can be carried out at any temperature, as long as there is a temperature difference between the hot and cold sides, the separation can be achieved.
2. During the process of the 2l short path distillation kit, the molecules escaping from the evaporation surface fly directly to the condensation surface without colliding with other molecules in the middle, and there is no possibility of returning to the evaporation surface in theory. Therefore, the 2l short path distillation kit The process is irreversible.
3. The 2l short path distillation kit process is free evaporation on the surface of the liquid layer without bubbling.
4. The separation factor of the separation ability of 2l short path distillation kit is related to vapor pressure and molecular weight.
1: The separation operation can be realized at the temperature below the boiling point of the material, as long as the pressure of the system is lower than the saturated vapor pressure of the light component of the material and the distance between the heating surface and the condensation surface is less than or equal to the molecular mean free path of the light component, The purpose of separation can be achieved.
2: Ordinary distillation is operated above the boiling point temperature of the material, so evaporation and condensation are a reversible process, and the separation operation of the 2l short path distillation kit can be realized below the boiling point temperature, so the evaporation and condensation of the 2l short path distillation kit are a irreversible process.
3: Ordinary distillation has bubbling and boiling phenomena. The separation operation of 2l short path distillation kit is realized below the boiling point temperature, so there is no bubbling and boiling phenomenon, which is conducive to maintaining a high degree of vacuum in the entire system.
