text: Ordinarily aluminum chloride has been considered as a compound that, when heated, will vaporize immediately from its solid state, and when cooled will sublime directly from vapor to solid in finely divided or crystalline fort, We have found that when aluminum chloride is heated under pressure, its own vapor pressure for instance, a point oftemperature and pressure is reached at and above which the body of aluminum chloride is held in liquid state and may be made to solidify from that state or may be made to pass from vapor state through the liquid I state into the solid state; and we make use of these peculiar properties in the production of a final solid cake of aluminum chloride, all as will be explained more in detail, together with illustrations of various apparatus for carrying on the process.
