| 摘要 |
This invention provides a process for the synthesis of ZSM-12 using the N,N-dimethylhexamethyleneimine cation as a directing agent. The process enables ZSM-12 to be produced at silica/alumina molar ratios below 50 with little or no co-production of impurity phases. Small crystal forms of ZSM-12 can also be produced using the process of the invention.
