Participants

Reactant 2

HCID 14766Sodium aluminate

HCID 26051Sodium orthosilicate

Product 1

HCID 19758701Molecular sieve

Conditions

Temperature: 68 °C

Procedure

By using the same starting material as that of Example 1, the sodium aluminate solution was heated at 70%° C. and stirred, and to which was mixed a sodium silicate solution heated at 68° C. over a period of about 4 minutes such that the total amount of the reaction solution was 1.75 kg in a 2-liter stainless steel container, in order to form a sodium aluminosilicate which as a whole was in a homogeneous gel-like form having the below-mentioned molar composition:
