Abstract
A novel microporous crystalline aluminosilicate designated DCM-2 is disclosed. The composition, as synthesized, contains lithium cations and is represented by the oxide composition: Li.sub.2 O.multidot.Al.sub.2 O.sub.3 .multidot.10SiO.sub.2. The lithium cations may be exchanged with hydrogen ions, and in the acid form the composition is useful as an adsorbent and as a catalyst for converting alkyl halides and alkanols to light hydrocarbons.
