Synthesis of β-nitroxyalkylnitramines

Abstractβ-Nitroxyalkylnitramines were obtained by nitration of β-hydroxyalkyl sulfamates, products of the condensation of derivatives of sulfamic acid with alkene oxides, by a mixture of HNO3 and H2SO4.

Synthesis and nitration of condensation products of sulfamates with aliphatic amines and formaldehyde

A method for the synthesis of 5-alkyl-1,3-dinitro-1,3,5-triazacyclohexanes and linear polynitramines was proposed. It includes the reaction of aliphatic amines with sulfamates and formaldehyde and nitration of the reaction products. The yield and composition of nitramino derivatives depend on the conditions of the condensation and nitration.

New plasticizers for energetic materials

Specific features of the synthesis of new nitroxy-containing N,N′-bis(alkylnitramine) mixtures have been considered. The results of studying the plasticizing ability of the mixtures with respect to various cellulose nitrates, as well as the performance data on energetic materials on their basis, have been reported. Combustion of both the plasticizers and compositions on their basis has been studied in detail.

Synthesis of 2-Substituted N-Nitrooxazolidines

A method was developed for preparation of N-nitrooxazolidines functionally substituted in position 2 consisting in nitration of reaction products obtained from N-(2-hydroxyethyl)sulfamate and 2-substituted acetaldehydes.

Synthesis ofN-(3-azido-2-nitroxypropyl)-,N-(2,3-diazidopropyl)-, andN-(2-azido-3-methoxypropyl)-N-alkylnitramines

N-(3-Azido-2-nitroxypropyl)-N-alkylnitramines andN-(2,3-diazidopropyl)-N-alkylnitramines were prepared by nitration and azidation ofN-alkyl-N-(2-hydroxy-3-chloropropyl)sulfamates andN-(3-azido-2-hydroxypropyl)-N-alkylsulfamates.

Synthesis ofN-3-chloroalkoxy-2-nitroxypropyl-N-alkylnitramines and their subsequent azidation

Nitration ofN-3-chloroalkoxy-2-hydroxypropyl-N-alkylsulfamates gave the correspondingN-3-chloroalkoxy-2-nitroxypropyl-N-alkylnitramines. Azidation of the latter resulted inN-azido-3-azidoalkoxypropyl-N-alkylnitramines.

Nucleophilic reactions in the N-nitrooxazolidine series

A number of new 2-and 5-substituted N-nitrooxazolidines were synthesized by nucleophilic replacement in 2-and 5-halomethyl-N-nitrooxazolidines.

Synthesis of Nitroesters Based on Methylol Derivatives of Parabanic and Isocyanuric Acids

Nitroesters synthesis based on methylol derivatives of parabanic and cyanuric acids was performed. The corresponding alloxan nitroxymethyl derivative was unstable.

Synthesis of 3-alkoxy-2-nitroxypropyl-N-alkylnitramines

It was shown that 3-alkoxy-2-nitroxypropyl-N-alkylnitramines can be prepared by nitration of the corresponding 3-alkoxy-2-hydroxypropyl-N-alkylsulfamates.
