The conclusion was drawn by the synthesis of molecular sieve: after mixed soluble glass and aluminium sulfate with proper proportion under room temperature, it was stirred stormily to react. And then we mixed with potassium hydroxide solution after filtrating. At last, the molecular sieves of potassium type was synthesized after the mixture reacted in the oven or autoclave for 24 hours. The molecular sieve was remodeled more than twice with ammonium chloride solution that the concentration was 3mol/L and then remodeled twice with the saturated sodium chloride solution. Finally the molecular sieve was changed into the sodium type. It was named W zeolite.
