摘要：

Titania, sulfated titania and chromium loaded sulfated titania were prepared by sol-gel method and characterized using different technique. Phenol is nitrated regioselectively by nitric acid using chromium loaded sulfated titania catalysts. A remarkable ortho selectivity is observed in solid state nitration to yield exclusively ortho-nitrophenol. Compared to the conventional process, phenol nitration over solid acid catalyst is a clean and environment friendly process. Catalytic activity well correlates with the Bronsted acid sites of these catalysts. (c) 2005 Elsevier B.V. All rights reserved.
