Description

Technical Field

[0001] The utility model relates to the technical field of condensers, in particular to a condenser for azeotropic distillation separation. Background Art

[0002] Azeotropic distillation refers to a series of technologies that destroy the azeotropic composition during distillation to perform distillation or fractionation. It is a method of distilling by forming an azeotrope with two organic solvents. For example, water can form a low-boiling azeotrope with trichloroethylene, carbon tetrachloride, chloroform, isoamyl alcohol, cyclohexane, and benzene, and the azeotrope can be distilled out by distillation. Since water and organic solvents are immiscible, the water layer can be easily separated from the organic solvent. It can be used to determine the moisture content in the sample and calculate the water content of the sample based on the volume of the distilled water. However, it is inconvenient to clean the condenser tube inside the azeotropic distillation condenser during use. Impurities will adhere to the surface of the condenser tube during long-term use, affecting the effect of subsequent condensation. For this reason, we propose a condenser for azeotropic distillation separation. Utility Model Content
