Disclosed herein are zeolite compositions comprising structural units of
the formulae:
##STR1##
wherein "B" and "C" are spacer groups comprising C2 to C20
hydrocarbyl groups; and R1 and R2 independently of
each other comprise alkali metal, hydrogen, or C1 to C20 alkyl
groups. The zeolite compositions further comprise structural units derived from
a heteropolyacid compound of the formula: (M3)3(M4)(M5)12O40;
where M3 comprises hydrogen or an alkali metal; M4 comprises
phosphorus or silicon, and M5 comprises tungsten or molybdenum. Methods
for preparing these zeolite compositions are also disclosed. The zeolite compositions
are useful as catalysts for producing bisphenols.
