Abstract
Abstract A process for preparing ZSM-14 zeolite, and a product thereof, is disclosed. The process uses an organic directing agent of the formula R"--O--R'--O.sup.- --A.sup.m+ where 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.
