Synthesis of ECR-1 using methyltriethanolammonium cations

A process for preparing an ECR-1 crystalline zeolite comprising:

• (a) preparing a reaction mixture comprising an oxide of sodium, an ammonium salt, water, a source of silica, a source of alumina and sodium aluminosilicate nucleating seeds, said reaction mixture having a composition, in terms of mole ratios of oxides, within the following ranges:
• ______________________________________ R.sub.2 O:Al.sub.2 O.sub.3 0.2 to 1.0 Na.sub.2 O:Al.sub.2 O.sub.3 1.0 to 7 SiO.sub.2 :Al.sub.2 O.sub.3 5 to 20 H.sub.2 O:Al.sub.2 O.sub.3 120 to 300 R.sub.2 O:Na.sub.2 O 0.05 to 0.4 ______________________________________
• where R is a (CH.sub.3)(C.sub.2 H.sub.4 OH).sub.3 N.sup.+, and said seeds being present in an amount to yield 1 to 15 mole percent of the total alumina content of the reaction mixture;
• (b) blending the reaction mixture sufficiently to form a substantially homogeneous mixture;
• (c) maintaining the reaction mixture at between about 120.degree. C. and 200.degree. C. under autogeneous pressure for a sufficient period of time to form crystals of a zeolite having a composition, in terms of mole ratios of oxides, in the range:
• 0.5 to 0.02R.sub.2 O:0.90 to 0.98Na.sub.2 0:Al.sub.2 O.sub.3 :5 to 12SiO.sub.2 :xH.sub.2 O
• where R and x are defined above, and such that the x-ray powder diffraction pattern of said zeolite is essentially identical to that given in Table 1, and
• (d) recovering said zeolite crystals.
