ABSTRACT Certain hydrogen phosphate and pyrophosphate compositions are employed as catalysts for organic condensation reactions. Particularly high conversions and selectivities are obtained by the use of synergistic mixtures of in cyclization reactions such as in the conversion of hydroxyethylpiperazine to triethylene- diamine and morpholine to dimethylaminoethylmorpholine.
