    • PURPOSE: A method for manufacturing zeolite and a method for manufacturing epsilon-caprolactam are provided to repeatedly use an aqueous solution containing ammonia and ammonium salt by effectively recycling ammonia and/or ammonium salt collected from a zeolite manufacturing process. CONSTITUTION: A method for manufacturing zeolite comprises the steps of: contacting crystals obtained from the hydrothermal synthesis of a silicon compound with an aqueous solution containing ammonia and ammonium salt; obtaining an aqueous solution containing ammonia and ammonium salt in which the concentration of silicon is adjusted to be lower than or equal to 100 weight ppm by mixing a resultant aqueous solution with at least one of ammonia, ammonium slat, and water; and circulating the aqueous solution containing ammonia and ammonium salt to the crystal contacting step. A method for epsilon-caprolactam comprises the steps of: manufacturing zeolite; and generating a Beckmann electric potential reaction between the zeolite and cyclohexanone oxime under a gaseous state.

    • PURPOSE: A manufacturing method of a nano-oxygen catalyst for removing a sick house syndrome is provided to remove volatile organic compounds such as formaldehyde, toluene, xylene, and benzene by simply coating the catalyst on the surface of an interior finishing material, and the catalyst can be used semi-permanently without the activity degradation of the catalyst which does not directly react with the other volatile organic compounds or contaminants. CONSTITUTION: A manufacturing method of a nano-oxygen catalyst for removing a sick house syndrome comprises the following steps: the first step of filling titanium tetrachloride and refined water in a ratio of 1:100 in a stainless tank at room temperature, and stirring after adding 0.20-0.39 mol of ammonia water; the second step of extracting a pure titanium dioxide solution, which is a separated lower layer, and filling the stainless tank with the solution; the third step of stirring the mixture after adding 0.23-0.35 mol of nitric acid, and stirring the mixture for 20-50 minutes after additionally adding 0.12-0.25 mol of silica sol; and the fourth step of stirring the mixture after adding 0.013-0.03 mol of acryl binder with minor portions of dispersant and EDTA.
