摘要：
A porous, crystalline material is described having the framework structure of ZSM-12 and a composition involving the molar relationship: X2O3:(n)YO2 wherein X is a trivalent element, Y is a tetravalent element and n is less than 60. The material has an average crystal size of the material is less than 0.1 micron and a Diffusion Parameter for mesitylene of at least 1000×10−6 sec−1 when measured at a temperature of 100° C. and a mesitylene pressure of 2 torr.
