| titleOfInvention | A method for producing 1,4-diazabicyclo [2.2.2] octane from ethylenediamine |
| abstract | The process for producing 1,4-diazabicyclo [2.2.2] octane from ethylenediamine consisting of deamination and cyclization of ethylene amine in the gas phase in the presence of a heterogeneous zeolite catalyst of crystalline structure ZSM-5 with a Si / Al molar ratio of 12 to 400, heterogeneous zeolite the catalyst of the crystalline structure ZSM-5 has a crystal size less than 0.5 microns, the process being carried out at a temperature of 300 to 400 degC, a pressure of 0.05 MPa to 0.5 MPa in the presence of water, where the ammonia-free reaction mixture is further rectified to an aqueous, fractional, crude 1,4-diazabicyclo [2.2.2] octane fraction, wherein the piperazine fraction containing ethylenediamine, piperazine, 1,4-diazabicyclo [2.2.2] octane , morpholine, 1-methylpiperazine, 2-methylpiperazine 1-ethylpiperazine is returned to the reaction zone. |
