Abstract
The conversion of ethanolamine to industrially important diazabicyclo [2.2.2] octane (DABCO) has been studied over the ZSM-5 zeolite. This t ransformation takes place via the piperazine route. With the increase in reaction temperature from 325 to 400 degrees C, ethanolamine conver sion increased from 4.5 to 82%, while the DABCO selectivity decreased from 71 to 47%. The catalyst stability is lower at higher ethanolamine conversion, while it improves at lower ethanolamine conversion.
