Solvents, who needs them? Silicoaluminophosphate zeolites with various frameworks have been successfully synthesized by a solvent-free route. Catalytic tests for the conversion of methanol to olefins show that thus obtained SAPO-34 (see picture) exhibited catalytic performance comparable to that of zeolites made by the conventional hydrothermal route.
