Japanese Patent JPS6215488
Kind Code:
B2
Abstract:
{PG,1 As synthesized by conventional technique, zeolite ZSM-11 is crystallized in the presence of substantial amount of at least one of the quaternary cations of a Group VA element of the Periodic Table of Elements. When synthesized in the conventional way, ZSM-11 contains said cations as well as substantial amount of sodium ions. To obtain a more catalytically active form of ZSM-11, the sodium ions must be exchanged to very low levels. By synthesizing zeolite ZSM-11 according to the present method, i.e. in the presence of one or more alkylenediamines having from 7 to 12 carbon atoms and with a specifically defined reaction mixture composition, ZSM-11 having different organic cations but the same crystal structure as conventionally prepared ZSM-11 is obtained. The ZSM-11 prepared in accordance hereto is very low in sodium content as synthesized.
