1. a kind of method that amino acid auxiliary prepares the Beta zeolite molecular sieve of chiral polymorph A enrichments, its step is as follows:

  • (1) silicon source, template and deionized water are proportionally added into reaction vessel, stir equal under closed, room temperature conditionIt is even, make silicon source complete hydrolysis;

    (2) by step (1) gained mixture in room temperature condition, open wide under system and stir to forming homogeneous gel;

    (3) step (2) gained gel is further dehydrated and obtains block dry glue, by gained bulk dry glue and solid amino, into homogeneous powder, loading reactor carries out hydrothermal crystallizing for acid, solid Fluorine source mixed grinding;

    (4) step (3) crystallization product is transferred out from the reactor for being cooled to room temperature, the solid deionized water that will be obtainedWashed, separated, dry roasting, so as to obtain the Beta zeolite molecular sieve of chiral polymorph A enrichment.
