The total nitrogen content in pure benzene obtained from the hydrogenation of crude benzene is high!
Thread Content
I would appreciate some guidance from experts. This device uses formamidine as the extractant, and the nitrogen content in pure benzene is relatively high. Could experts tell me what might be the reasons for this?
It depends on whether it is NFM entrainment or decomposition; each case needs to be analyzed on its own.
Generally, it is due to extraction (extractive distillation); when N-methylmorpholine is used as an extractant, some carrying over occurs, which certainly results in a high nitrogen content.
