Cubic P zeolite

A comparison of synthesis of the conventional sort, proceeding via a silica-alumina gel intermediate, and the synthesis used here starting with Cubic P zeolite, is shown in Figure 1. Hie synthesis with Cubic P is at least five times as fast as the conventional synthesis. The template used was 1-Ada.
