ABSTRACT:
A direct and simplified process is described for making anionic clays having the hydrotalcite structure which contain as the intercalating anion a pH-dependent, essentially carbonate-free, inorganic anion. Hydrotalcite-type clays made by the process from a number of divalent and trivalent metal ions and pH-dependent, boron-containing anions and transition element metalates are useful in the conversion of hydrocarbons.
