    • The synthesis of a crystalline aluminophosphate or silicoaluminophosphate molecular sieve having a chabazite-type framework type is conducted in the presence of an organic directing agent having the formula (I) [R1R2R3N—R4]+X−  (I) wherein R1, R2 and R3 are independently selected from the group consisting of alkyl groups having from 1 to 3 carbon atoms and hydroxyalkyl groups having from 1 to 3 carbon atoms; R4 is selected from the group consisting of 4- to 8-membered cycloalkyl groups, optionally substituted by 1 to 3 alkyl groups having from 1 to 3 carbon atoms; 4- to 8-membered heterocyclic groups having from 1 to 3 heteroatoms, said heterocyclic groups being optionally substituted by 1 to 3 alkyl groups having from 1 to 3 carbon atoms and the heteroatoms in said heterocyclic groups being selected from the group consisting of O, N, and S; and aromatic groups optionally substituted by 1 to 3 alkyl groups, said alkyl groups having from 1 to 3 carbon atoms; and X− is an anion.
    • 在具有式(I)的有机导向剂的存在下进行具有菱沸石型骨架型的结晶铝磷酸盐或硅铝磷酸盐分子筛的合成<?in-line-formula description =“In-Line Formulas”end = “铅”?> [R 1] 2 3 3 4 (I)<?in-line-formula description =“In-line Formulas”end =“tail”?>其中R 1,R 2, 2和R 3独立地选自具有1至3个碳原子的烷基和具有1至3个碳原子的羟基烷基; R 4选自4-8元环烷基,任选被1至3个具有1至3个碳原子的烷基取代; 具有1至3个杂原子的4-至8-元杂环基,所述杂环基团任选被1至3个具有1至3个碳原子的烷基取代,所述杂环基中的杂原子选自O, N和S; 和任选被1至3个烷基取代的芳族基团,所述烷基具有1至3个碳原子; 而X - 是阴离子。
