Sample preparation using azeotropic distillation
Open the catalog to page 1Azeotrope Destillation Numerous substances form azeotropic mixtures together. Such mixtures cannot be separated into their individual components by distillation, as the liquid and vapor phases have the same composition. This property of an azeotrope can be utilized with the KF evaporator to separate the water contained in a sample from the matrix and to «pull it out» of the mixture. Mixing water and toluene forms an azeotrope. The boiling point of this mixture (84 °C) is signicantly lower than the boiling point of the two components (water: 100 °C, toluene: 110 °C). The composition of the...
Open the catalog to page 2Applications The KF Evaporator is used for sample preparation in Karl Fischer titration. If you wish to determine the water content of liquid samples, but these are neither suitable for the direct nor for the oven method, the KF Evaporator could be the solution. Typical samples are crude oil, tar, turpentine, resins or also terpenes. As only the water in the sample reaches the titration cell, both secondary reactions with the Karl Fischer reagents, as well as contamination of the cell and electrode(s), are avoided. The oven is raised with a nger and the sample heated. Secondary reactions...
