Patent Images
1. In a method for preparing a molecular sieve having a mole ratio of a first oxide selected from silicon oxide, germanium oxide, phosphorous oxide, and mixtures thereof to a second oxide selected from aluminum oxide, gallium oxide, iron oxide, boron oxide, and mixtures thereof of one or greater which process comprises preparing an aqueous reaction mixture comprising a source of a first oxide selected from silicon oxide, germanium oxide, phosphorous oxide, and mixtures thereof, a second oxide selected from aluminum oxide, gallium oxide, iron oxide, boron oxide, and mixtures thereof, an alkali metal oxide and an organic templating compound and maintaining said mixture under crystallization conditions until crystals of said molecular sieve are formed, the improvement wherein said organic templating compound is an adamantane compound wherein the adamantane compound has the formula:
- ##STR5## wherein Z is methylene or a covalent bond;
R1 is OH, N(X1 X2) wherein each of X1 and X2 independently is hydrogen or lower alkyl, or a moiety of the formula N.sup.⊕
(Y1 Y2 Y3)A.sup.⊖
, wherein each of Y1, Y2 and Y3 independently is lower alkyl and A.sup.⊖
is an anion which is not detrimental to the formation of the molecular sieve;
R2 is hydrogen or lower alkyl;
each of R3 and R4 independently is hydrogen, lower alkyl, OH, N(X1,X2) wherein X1 and X2 are as defined above, or a moiety of the formula N.sup.⊕
(Y1 Y2 Y3)A.sup.⊖
wherein each of Y1, Y2, Y3 and A.sup.⊖
are as defined above; and
##STR6## wherein Z is methylene or a covalent bond;
R5 is hydrogen or lower alkyl;
R6 is OH, N(X1 X2) wherein each of X1 and X2 independently is hydrogen or lower alkyl, or a moiety of the formula N.sup.⊕
(Y1 Y2 Y3).sup.⊖
wherein each of Y1, Y2 and Y3 independently is lower alkyl and A.sup.⊖
is an anion which is not detrimental to the formation of the molecular sieve;
each of R7 and R8 is hydrogen, lower alkyl, OH, N(X1 X2), wherein each of X1 and X2 are as defined above, or a moiety of the formula N.sup.⊕
(Y1 Y2 Y3).sup.⊖
wherein each of Y1, Y2 and Y3 and A.sup.⊖
are as defined above.
