Crystallinity and silicon incorporation are confirmed by XRD, XRF, N, sorption study, TG/DTA, SEM. pyridine TPD technique and hydroxyl region FT-IR. These materials with high Si concentration show higher activity for toluene alkylation reaction than samples prepared with up to 0.1 molar ratio of silica in the gel of aqueous media.</p>10aaqueous10aFT-IR10ahydroxyl region10anon-aqueous10aSAPO-510aSEM10aTG/DTA10aXRD1 aVenkatathri, N  uhttps://library.ncl.res.in/content/synthesis-high-silica-content-silicoaluminophosphate-5-sapo-5-non-aqueous-medium-using-0
