ABSTRACT:
Strontium pyro-, monohydrogen, and dihydrogen phosphates are employed as catalysts for acid catalyzed organic condensation reactions. High conversion and exceptionally high selectivity are obtained by use of such catalysts in cyclization reactions such as in the conversion of hydroxyethylpiperazine to triethylenediamine.
