The material 1,5-Dinitroxy-3-nitrazapentane (abbreviated DINA) belongs to the class of active nitroplasticizers, which in recent times, partially or completely replace nitroglycerin in the barrels. Previously, the method for laboratory synthesis of DINA was described, which included the reaction of diethanolamine and nitric acid, followed by the dehydration of intermediate 1,5-dinitroxy-3-aza pentane nitrate. According to this procedure, several hundred kilograms of DINA was produced which was incorporated into barutic mixtures and showed good and expected results. So far, DINA has been manufactured and manufactured in the world in two ways. The first method is a one-step process where, at one stage of the reaction, nitration of diethanolamine and dehydration of the rewarded 1,5-dinitroxy-3-aza pentane nitrate in DINA is carried out. This is achieved by simultaneous dosing of diethanolamine and acetic anhydride to nitric acid. The second method is a two step process where, in the first phase, a so-called 1,5-dinitroxy-3-aza pentane nitrate is generated by the reaction between diethanolamine and nitric acid, which is dehydrated in a particular reaction stage in DINA by an acetic anhydride, in the presence of suitable catalysts. As already mentioned, it was decided to win the procedure for the production of DINA based on a two-stage reaction, that is, the reaction of diethanolamine and nitric acid as the first phase and dehydration as the second phase of the reaction.
