摘要：

Cosolvents such as hexamethylphosphoramide and dimethyl sulfoxide added to typical zeolite A and X synthesis preparations influence the nucleation process by enhanced solvation of cations, by decreased solvation of hydroxide ions, and by lowering the solubility of aluminosilicate species. These effects are manifested in a faster nucleation process and increased yields at high Si/Al ratio reactant mixtures.
