Abstract
There is provided a system for the preparation of liquids from at least one solid and at least one liquid phase. The system is composed of a vessel in which the solid or solids are located and a drying chamber which is connected to the vessel or can be connected to the vessel. The drying chamber is separated from the vessel interior by a separating means which is permeable to water vapour but is impermeable to liquids. The system is suitable for the production of liquids from moisture-sensitive solids. These solids can be stored in the vessel since the air humidity in the interior is lowered by the desiccant. The preparation of the liquid by addition of a liquid phase can be carried out in one and the same vessel since the desiccant is separated from the vessel interior.
