Participants

Reactant 2

HCID 14766Sodium aluminate

HCID 26051Sodium orthosilicate

Product 1

HCID 19758701Molecular sieve

Procedure

The sodium silicate solution and the sodium aluminate solution were slowly mixed together with stirring under the following molar composition conditions so that the total amount of the reaction solution was 5 kg in a 20-liter stainless steel container, in order to form a sodium aluminosilicate gel which as a whole was homogeneous.
