Method of producing a sorptive body, particularly for eliminating odors, air freshening, etc. and the resultant product

In a method of producing a sorptive body for use in filtering air and/or in eliminating odors, providing air freshening, and the like, in which finely ground solid particles of a sorptive substance or a composition containing a sorptive substance are mixed with a binding agent and are thereby bound into a cohesive body, the improvement comprising:

• combining said finely ground solid particles with at least one liquid sorbate before mixing said solid particles with a binding agent, said solid particles having pores and capillaries for absorbing said sorbate, said sorbate being absorbable in said pores and capillaries, and the conditions of said combining being such that said sorbate is absorbed in said capillaries and pores;
• mixing said combined solid particles and absorbed sorbate with a binding agent comprising a settable binder composition in a liquid solvent, said binder composition being settable upon evaporation of said liquid solvent at a temperature higher than the boiling point of said sorbate so as to bind said solid particles together as a cohesive sorptive body;
• shaping said mixture and/or applying said mixture to a carrier body so as to form a cohesive sorptive body for use in filtering air and/or in eliminating odors, providing air freshening and the like;
• and,
• applying heat to said shaped and/or supported mixture so as to cause evaporation of said liquid solvent from said mixture, setting of said binder composition so as to bind said solid particles together in said cohesive sorptive body, and expulsion of said sorbate from said solid particles during the setting of said binder composition, the amount of said binder composition not exceeding 30% of the weight of said sorptive substance and the amount of said sorbate expelled from said solid particles during setting of said binder composition providing a connected open system of pores and capillaries in said binder composition for passage of air through said cohesive body and contact of said air with said sorptive substance.
