Synthesis method of ZSM-11 molecular sieve and ZSM-11 molecular sieve synthesized through same

The invention relates to a synthesis method of a ZSM-11 molecular sieve and the ZSM-11 molecular sieve synthesized through same, and mainly solves the problems in the prior art that the product purity of the synthesized ZSM-11 molecular sieve is not high, and the content of an impurity ZSM-5 molecular sieve is high. According to the synthesis method disclosed by the invention, the problems are preferably solved by adopting the technical scheme which comprises the following steps of enabling a silicon source, an aluminum source, an alkali source and an organic template agent to be in contact with water under a crystallization condition, thus obtaining a molecular sieve; optionally, roasting the obtained molecular sieve, wherein the organic template agent R is selected from at least one of 1,3-cyclohexanol dimethylamine or 1,4-cyclohexanol dimethylamine, and the synthesis method can be used in industrial production of the ZSM-11 composite molecular sieve.
