  • Triethylenediamine preparation via phosphate catalysts
    Patent number: 4521600
    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 triethylenediamine and morpholine to dimethylaminoethylmorpholine.

  • Process for preparing a platinum/rhodium catalyst
    Patent number: 4407738
    Abstract: The process for preparing a regionalized platinum/rhodium catalyst using a single impregnating step. The process is particularly effective in preparing such a catalyst for use as an automotive emissions control catalyst. A substantially alumina support is impregnated in a platinum/rhodium controlled acidic solution of a strong acid and an ammonium salt or equivalent thereof.
