Nanotitania catalyzes the chemoselective hydration and alkoxylation of epoxides

Glycols and ethoxy– and propoxy–alcohols are fundamental chemicals in industry, with annual productions of millions of tons, still manufactured in many cases with corrosive and unrecoverable catalysts such as KOH, amines and BF•OEt. Here we show that commercially available, inexpensive, non–toxic, s...
