Salts of 3,5-dinitro-1H-1,2,4-triazole, a building block for energetic materials, have been prepared and fully characterized. Most of the studied salts exhibit high thermal stability and very low shock and friction sensitivities. 3,5-Dinitro-1,2,4-triazolates with the nitrogen-rich ammonium, guanidinium, aminoguanidinium, and aminotetrazolium cations are energetic and have potential for energet...
Context. The nitrogen reservoir in planetary systems is a long standing problem. Part of the N-bearing molecules probably incorporated into ice bulk during cold phases stellar evolution, and may be gradually released gas phase when heated, such as active comets. chemical nature N-reservoir should greatly influence how, what form N returns to phase, or refractory material forming bodies. Aims. W...
For a long period of time, saturated quaternary ammonium salts have been used as components compositions that antimicrobial properties against certain strains microorganisms. The disadvantage using such is the formation resistance some microorganisms to latter. Thus, it seems relevant create based on with which had no contact in environment. This article presents results experimental studies ac...
Two series of rosin quaternary ammonium salts (QAS) were synthesized using the same path. The structure of the target products was characterized by HPLC, MS, IR, and 1 HNMR, and the bioactivity was determined by filter paper method using Trametes versicolor (white-rot fungus) and Gloeophyllum trabeum (brown-rot fungus), which are two kinds of general wood decay fungi in nature. The results show...
