Synthesis of Zeolite Monoliths for Flow Continuous Processes. The Case of Sodalite as a Basic Catalyst

A simple method has been established for the fabrication of zeolite monoliths with a hierarchical pore system by pseudomorphic transformation of a meso-/macroporous silica monolith. Sodalite monoliths with homogeneous macroporous network were obtained and successfully used as a basic catalyst for reactions in liquid phase under flow conditions for more than 200 h.
