Abstract
PURPOSE: To obtain X-type zeolite composed of fine crystalline particles by forming amorphous aluminum silicate from alkali metallic aluminate, alkali metallic silicate and alkali metallic hydroxide and agitating the alumium silicate at a specified temp.
CONSTITUTION: Alkali metallic aluminate, alkali metallic silicate and alkali metallic hydroxide as starting materials are mixed with water. The molar ratio of SiO2/Al2O3 in the starting materials and that of M2O/A2O3 are specified to 2.5W3.6 and 3.6W6.5, respectively. The mixture is adjusted to 1.3W3.5 alkalinity with polyaminopolycarboxylic acid compound and agitated to form amorphous aluminum silicate. This slurry is kept at 10W65°C for ≥20min while agitating, and it is heated to 80W105°C in 30min to crystallize aluminum silicate, which is then kept at the temp. for ≥1hr to obtain X-type zeolite composed of fine crystalline particles contg. no different kind of zeolite and no impurities.
