Abstract

Abstract Titanium substituted silicalite-1 (TS-1) samples have been synthesized using hexanediamine (C6DN) and tetrapropylammonium bromide (TPABr). Following this method, titanium could be incorporated up to a level of about 2 Ti/unit cell in the framework of silicalite-1. Crystals had a typical habit, very different from those obtained with standard syntheses, which led to exceptionnally high para/ortho ratios in the hydroxylation of phenol with hydrogen peroxide.
