Abstract: The molecular sieve VPI-5 was synthesized by using various organic amines (DEA, Di-PA, DBA, DPenA, TBA, DEOAand TEOA) as the structure-directing agent. The use of DPAenlarged the range of the crystallization temperature from 110℃ to 190℃ in the synthesis of VPI-5, while the use of TEOAchanged the composition of the reactants in a broad variety. Diamines are the typical amines in the synthesis of VPI-5. Among them DBAand DPAare the most favorite structure-directing agents for the synthesis of VPI-5 molecular sieve.
