How to prepare 95 ethanol from absolute ethanol

How to converting 95 ethanol to absolute ethanol

In order to produce absolute ethanol with an ethanol content of 99.5%, our most commonly used and simplest preparation method is the quicklime method, which uses quicklime to react with water in industrial alcohol to produce slaked lime which is non-volatile and generally not decomposed by heating to obtain Absolute ethanol. In order to allow the reaction to proceed sufficiently, in addition to mixing the reactants overnight, they were also heated to reflux for a period of time. The prepared absolute ethanol was collected by direct distillation.

      The purity of the absolute ethanol prepared above can reach 99.5%. If you want to make absolute ethanol with a purity of> 99.95%. It takes some effort. The method is to further process 99.5% absolute ethanol and sodium metal prepared above, and remove the residual trace moisture.
