Abstract
An improved process for preparing ZSM-5 zeolite, and a product thereof, is disclosed. The process uses an organic anionic directing agent of the formula ##STR1## wherein A is a cation having a valence m, R' is an inorganic or an organic acid moiety, and R" is a linear or branched aliphatic, aromatic or alkyl aromatic group. The ZSM-5 zeolite is synthesized at the SiO.sub.2 /Al.sub.2 O.sub.3 molar ratios of 30 to 1000.
