SCHEDULED MAINTENANCE
Reaction of synthetic zeolite Na-Y with SiCl4 yields an essentially aluminium-free faujasite structure which is highly crystalline, and which, when studied by 29Si n.m.r. spectroscopy with magic-angle-spinning, gives a spectrum consisting of a single, sharp peak characteristic of regular, Si(4 Si) lattice ordering.
