Anyone tried this method..?
10 g of aluminum chloride hexahydrate is taken and put into a beaker, water is added for dissolving to prepare a solution, 95 percent ethanol is slowly poured into the beaker, after crystals in the beaker are fully separated out, solid-liquid separation is carried out in a centrifugal separator, and white crystals, namely the anhydrous aluminum chloride, are obtained. The concentration of ethanol poured in according to the above method may also be 75%, 99.5%. The solid-liquid separation according to the above method can also be carried out by other methods such as ordinary filtration. It is also possible to remove impurities by filtration after preparation of the aqueous solution.
