N-(2-sulfatoethyl) piperazine sulfate and it preparation |
| abstract |
Preparation of N-(2-sulfatoethyl)piperazine sulfate by reacting N-(2-hydroxyethyl)piperazine in a mixture of high- or relatively high-percentage sulfuric acid and oleum or chlorosulfonic acid at temperatures of about 80 DEG C to about 250 DEG C, introducing the sulfation mixture formed into a water-miscible aliphatic alcohol and isolating the N-(2-sulfatoethyl)piperazine sulfate formed. |
