Research progress of ZSM-12 molecular sieve;

ZSM-12 molecular sieve, which was applied to synthesize 2,6-DMN byshape-selective alkylation of naphthalene, was prepared by hydrothermal method.

Shape-selective synthesis of 2,6-dimethylnaphthalene over ZSM-12 zeolite modified by desilication in alkaline medium

Mesoporous ZSM-12 zeolite was prepared by dual template in-situ method, desilication in alkaline medium and zeolite as silica source method.

Mesoporous ZSM-12 zeolite was prepared by desilication treatment in alkaline medium.

The IR spectra of pramework vibration for Fe-Si-ZSM-12 zeolite indicated that the absorption bands of its building units were at 545,580 and 630cm~(-1),while those of Fe-O-Si bonds were at 660 and 780 cm~(-1) which shifted toward higher values with increacing iron conten(?).
