ABSTRACT:
Salts and acids containing a triheteropolyanion in which one addenda atom of a heterododecatungstate or heterododecamolybdate is replaced by one tin atom or by two germanium atoms, in which the tin atom or the germanium atoms are bonded to a ligated transition metal, have outstanding utility as catalysts for the oligomerization of terephthalic acid with ethylene glycol, and for the isomerization of 1-butene, and for the dehydration of 2-butanol and subsequent isomerization of the 1-butene formed.
