Method of Washing Solids with Liquified Gases.
Abstract
The general object of this invention is to provide a method of washing solids with liquified gases without contamination from outside air or moisture. A further object is to provide such a method wherein the washing solvent is a moisture sensitive liquid having relatively high vapor pressures at room temperature. A particular object of the invention is to provide such a method where the washing solvent is liquidified sulfur dioxide. It has now been found that the aforementioned objects can be attained by a method including the steps of: (1) placing the solid to be washed in a dry vessel under an inert atmosphere, (2) evacuating the vessel, (3) introducing the liquified gas solvent into the vessel, (4) washing the solid with the liquified gas solvent, and (5) removing the solvent by the application of vacuum. Keywords: Patent Applications.
