Dehydration of butanols on copper-containing zirconium orthophosphates
The catalytic properties of ternary zirconium phosphates N a1-2xCuxZr2(PO4)3 in the transformations of butanols were been studied. It was found that the structure of alcohol and the copper content (x = 0, 0.15, 0.25, 0.35) affect the rate and selectivity
