Method of making triethylenediamine |
| abstract |
Strontium diorthophosphate is employed as catalyst for acid catalyzed organic condensation reactions. High conversion and exceptionally high selectivity are obtained by use of strontium diorthophosphate in cyclization reactions such as in the conversion of hydroxyethylpiperazine to triethylenediamine. |
