ABSTRACT:
Solvent-drying, particularly of water-wetted materials, is accomplished through the use of specific azeotropic mixed-solvent systems. The azeotropic systems used in the method of the invention are those which form two or more separate layers, in which the water distribution equilibrium favors the concentration of water or other liquid being removed in one layer over the other. The water or other liquid, therefore, concentrates in one layer facilitating removal by separation of the layers. Drying of the material takes place in the other layer which maintains a constant liquid concentration sufficiently low so as to produce a substantially dried product. Temperature control of the solvent bath and separator contents results in a single-layer drying bath and facilitates separation in a preferred embodiment.
