THE ACIDIC PROPERTIES CHARACTERIZATION OF ZIRCONIA-SULFONATE (ZrO2–SO4)
The present work has its basis on the system zirconia-sulfonate in order to study the influence in the variation of the content of the sulfonium ion, carrying out the addition of the agent in situ at a pH=1.8. Results show that solids with a tetragonal type phase, and a distribution of acid sites of the Brönsted and Lewis type with a acid strength of the order of Ho= -14.52 were obtained.
