A 2-hydroxyethyl acrylate having only one hydroxyl group is nitrated in a 1:1 volumetric mixture of nitric acid and sulfuric acid therein forming 2-nitratoethyl acrylate. The 2-nitratoethyl acrylate is minimally soluble in a quenched cold acid water mixture, which enables relatively easy isolation of about 96% purity 2-nitratoethyl acrylate at a yield of about 85%.

In order to avoid problems associated with fume-off that characterize the conventional synthesis method of making diglycerol tetranitrate, synthesis is performed in a medium including a mixed acid phase and an inert organic phase. The mixed acid phase contains, as ingredients, at least one nitronium ion source and at least one acid having sufficient strength to generate nitronium ions from the nitronium ion source. The nitronium ions in the mixed acid nitrate diglycerol to form diglycerol tetranitrate, which is then received into the organic liquid. The organic liquid, which preferably is a chlorocarbon such as dichloromethane, is insoluble with diglycerol but soluble with diglycerol tetranitrate. The inert organic phase is then treated to neutralize any acid contained in the inert organic phase, and the diglycerol tetranitrate is separated from the inert organic phase.
