Abstract
This invention relates to phase transfer catalysis (PTC) using a composition of synthetic ultra-large pore crystalline material which contains a cation of an onium compound, e.g. cetyltrimethylammonium, within the pores of said material. The crystalline material has, after calcination, an X-ray diffraction pattern with at least one peak at a d-spacing greater than 18 Angstrom Units and a benzene adsorption capacity of greater than 15 grams benzene per 100 grams of said material at 6.7 kPa (50 torr) and 25.degree. C.
