摘要：
In a synthetic porous crystalline material having the structure of ZSM-5 and a composition involving the molar relationship: X2O3:(n)YO2, wherein X is a trivalent element; Y is a tetravalent element; and n is greater than about 12, the crystals have a major dimension of at least about 0.5 micron and surface framework YO2/X2O3 ratio which is no more than 20 % less than the bulk framework YO2/X2O3 ratio of the crystal. The material is synthesized using an amino-acid as a directing agent.
