Organo tin precursors for synthesis of zeolite Sn-Beta for alcohol ring opening of epoxides

Abstract

Lewis acid zeolite Sn-Beta is hydrothermally synthesized using orano tin precursors. NMR experiments indicate that organotin precursors affect the site formed, with methyl tin trichloride increasing the fraction of open defect sites. Catalytic testing showed that the open defect sites are highly active for the epoxide ring opening with methanol.
