1. a molecular sieve, after synthesizing in it, the form of former state and this molecular sieve of burnt form have such X-rayDiffraction pattern, it peak including there is the d-spacing maximum in the range of 14.17 to 12.57 angstroms, have at 12.1 to 12.56 angstromsIn the range of the peak of d-spacing maximum, and the non-separated scattering between 8.66 to 12.0 angstroms, or arrive 10.14 havingThe peak of the d-spacing maximum in the range of 12.0 angstroms and have d-spacing maximum in the range of 8.66 to 10.13 angstroms peak itBetween demonstrate paddy, this paddy minimum point by the mensuration intensity of background correction not less than being connected to 10.14 to 12.0 angstroms of scopesIn maximum with on the line of the maximum in the range of 8.66 to 10.13 angstroms at the 50% of identical XRD d-spacing point,Wherein said molecular sieve is prepared by the method comprised the following steps:

  • A () provides and comprises EMM-10-P family compositions, acidic composition and the mixture of interval dose;

    B () processes described mixture under processing conditions and comprises the product of the molecular sieve EMM-12 of former state after synthesis to be formed;

    WithC () reclaims the molecular sieve EMM-12 of former state after described synthesis,Wherein said EMM-10-P family compositions includes that EMM-10-P, described acidic composition include 1N aqueous solution of nitric acid, instituteState interval dose and include that di ethoxy di methyl-monosilane, described treatment conditions are included in the temperature in the range of 90-170 DEG C and at 1-24Time in the range of hour.
