생산 방법
A total of 25 g of potassium nitrocarbamate is introduced in small portions into a mixture of 25 ml of concentrated H3SO4 and 200 g of ice, and the solution is saturated with (NH4)SSO4. The mixture is then extracted 30 times with ether until an evaporated sample no longer evolves gas upon adding a drop of ammonia. The ether solution is put in a flask and evaporated by a dry air stream at room temperature. The residue is dissolved in a small quantity of absolute ether, and the nitramide is precipitated with ligroin. It is washed with petroleum ether and dried on clay. The lengthy ether extraction can be avoided by superimposing a layer of ether on the aqueous solution and solidifying the latter while stirring by cooling it with a Dry Ice-acetone mixture. The ether is then decanted. Just four repetitions of this process result in the transfer of 80% of the nitramide to the ether.
