Abstract

The epoxidation of allyl alcohol with hydrogen peroxide catalysed by the microporous titanium silicalite TS-1 has been investigated with respect to the effect of the method of catalyst preparation. Three methods of TS-1 synthesis have been studied using the standard tetrapropyl-ammonium cation as template (i) using tetraethyl orthosilicate, tetraethyl orthotitanate as reagents, (ii) using a fluoride method and (iii)using tetrabutyl orthotitanate as the titanium source, The TS-1 samples were characterised by electron microscopy, X-ray diffraction and infrared spectroscopy. The method of preparation controlled the morphology of the TS-1 crystals and in particular the crystallisation time wasfound to be an important parameter. Data are presented that correlatethe activity for the epoxidation of allyl alcohol with the morphologyof TS-1. In addition it is found that the catalytic activity of Ts-1 for this reaction is not related to the intensity or presence of the infrared absorption band at ca. 960 cm(-1).
