Reaction Steps

Tablet also lists the important synthesis parameters for the ion-exchange in the preparation of example 6. A copper acetate solution was prepared by dissolving 57.5 g copper acetate monohydrate in 2822.5 g deionized water in a jacketed 4 Liter glass reactor. This solution was heated to 60° C. before addition of 360 g of the Na-CHA (example 1B). 150 g of deionized water was used to wash the reactor walls to insure all zeolite was in solution. The volume of the exchange slurry was kept constant at a liquid:solid ratio of 8:1. The temperature of 60° C. was maintained for 8 hours during which the pH ranged from 4.75 to 4.5. After 8 hours of ion-exchange the slurry was filtered hot over a 33 cm diameter Buechner funnel using 541 Whatmann filter paper (>25 μm filtration). The filtercake was then washed with deionized water until the conductivity of the washwater reached 200 μScm−1. The sample was washed with room temperature washwater. The resulting powder was then dried in an oven at 120° C. for 16 hours.
