Temperature-controlled phase transfer hydrothermal synthesis of MWW zeolites
Abstract
Temperature-controlled phase transfer hydrothermal synthesis of MWW zeolites was realized with hexamethyleneimine as a structure-directing agent and aniline as a structure-promoting agent. During crystallization, hexamethyleneimine and aniline were completely soluble. After crystallization with decreased temperature, aniline extracted hexamethyleneimine from the mother liquid to the organic phase for reuse.
