✦ Synopsis

Cubic P was shown to be an intermediate phase in the synthesis of several high silica organozeolites. Cubic P results from the parameters of the crystallization field studied. Each organozeolite is specified by a given organocation. Cycloalkyl substituents lead to organozeolites much better than linear groups on the charged nitrogen. A kinetic analysis of the transformations shows that pH increases with organozeolite formation. The mass and Si02/A1203 values also increase and are proportional to organocation uptake into the solid phase. The Na20/A1203 ratio decreases. The four organozeolite systems studied show variable rates and the difference in organocation structure is discussed in this regard.
