Synthesis of crystalline aluminosilicate molecular sieves

摘要: Crystalline aluminosilicate molecular sieves are prepared by (1) forming an aqueous mixture of oxide aluminum, silicon, a metal or ammonium cation and suitable oxygen-containing monomeric organic template compound, (2) maintaining the pH such between 9 14, (3) crystallizing mixture. The templates include ethanolamine, diethanolamine, triethanolamine, ethylethanolamine, ethyldiethanolamine, 2-amino-2-ethyl-1,3-propanediol, morpholine, alkali complexed tetrahydrofuran, dioxane, dioxolane, crown ethers. aluminosilicates mordenite, ferrierite, ZSM-4, ZSM-5.
