Sodium aluminate → Molecular sieve

Participants

Reaction Conditions

Reaction Steps

The same starting materials as those of Example 1 were used. That is, the sodium aluminate solution was heated at 90° C. and was stirred, and to which was mixed the sodium silicate solution heated at 80° C. over a period of about 4 minutes so that the total amount of the reaction solution was 1.75 kg in a 2-liter stainless steel container, in order to form a wholly homogeneous gel-like sodium aluminosilicate having the following molar composition.
