HYDROTHERMAL SYNTHESIS OF ZEOLITE N ALUMINOSILICATES
摘要
<p>A process for making aluminosilicates of zeolite N structure including the steps of: (i) combining a water soluble monovalent alkali metal or ammonium cation with a solution of suitable anions in a basic solution and an aluminosilicate to form a resultant mixture having a pH greater than 12 and a KOH molarity greater than 1.30; (ii) heating and stirring the resultant mixture to a temperature of between 100oC and 250oC excluding a boiling point of the mixture for a time of between 1 minute and 100 hours until a crystalline product of zeolite N structure is formed as determined by X-ray diffraction or other suitable characteristic; and (iii) separating the product from the mixture whereby said product is a solid with zeolite N structure.</p>
