Process for the synthesis of cyclic polynitrogenated compounds |
| abstract |
ABSTRACT PROCESS FOR THE SYNTHESIS OF CYCLIC POLYNITROGENATED COMPOUNDS. This invention relates to a method for the synthesis of cyclic polyamines that proceeds by reaction of a diamine with the acrylonitrile and in which the reduction steps are carried out with Raney alloy instead of using hydrogen under pressure in the presence of Raney nickel. This invention also relates to the new compounds prepared according to the process. |
