Simple and Green Synthesis of a Novel Fluoro-Nitrato Energetic Plasticizer
Over the last few decades, research into development of novel energetic plasticizers has been gaining a lot of interest, for example, bis(2,2-dinitro propyl)acetal, dinitro-diaza-alkanes (DNDA-57), 1,2,4-butanetrioltrinitrate (BTTN), and N,N-butyl-N′(2-nitroxy-ethyl) nitramine as energetic plasticizers for poly(3-nitratomethyl-3-methyloxe- tane)

EnRI has successfully synthesized energetic polymer plasticizers namely; low molecular weight GAP and azido terminated GAP (GAP-A). These energetic polymer based plasticizers are structurally similar to binder matrix and resist the migration due to enhanced miscibility.
Review of novel energetic polymers and binders - Taylor & Francis
With the addition of nitro groups, N-HTPB is miscible with energetic plasticizers with superior oxygen balance and burn rate than HTPB. N-HPTB has shown to be thermally stable up to 170°C, and propellants using N-HTPB also shows higher density and burn rate than propellants using HTPB as its binder [Citation 10, Citation 41 – Citation 45].
Synthesis and characterization of novel energetic plasticizers based on
The thermal analysis of plasticizers indicated Tg of TNPGN is lower than PGN and other synthesized plasticizers. Also, decomposition temperature (thermal stability) of TNPGN (251°C) is higher than PGN (209°C). Therefore, TNPGN has potential as a novel energetic plasticizer for propellant.

- What is the practical application of Energetic plasticizers?
- The practical application of energetic plasticizers is still limited, and it is necessary to develop new energetic plasticizers. researchers can use computer simulation technology to study the structure, energy characteristics (such as detonation velocity, detonation pressure, and specific impulse), and stability of compounds.
- What are energetic phthalate plasticizers based on imidazolium ionic liquids?
- In this study, a new class of energetic phthalate plasticizers based on imidazolium ionic liquids (ILs) were synthesized. The structure of the synthesized compounds was confirmed by 1 HNMR, 13 CNMR, and FT-IR. The thermal stability of nitrocellulose (NC)/plasticizer blends was also evaluated by thermogravimetric analysis (TGA).

- How many types of azidonitramine Energetic plasticizers are there?
- Despite the reporting of over 20 types of azidonitramine energetic plasticizers, there is no comprehensive summary or analysis of these substances. Hence, this review comprehensively analyzes the synthesis, structure, physical and chemical properties, energy performance, and applications of azidonitramine energetic plasticizers.
- Why are plasticizers used in propellant formulations?
- The common plasticizers are inert, so they cause to reduce the energetic properties of explosives and propellants. Energetic plasticizers have been used in propellant formulations in order to improve their mechanical properties and specific impulse. 1, 2
- Which method is used for synthesis of new energetic plasticizers?
- For all plasticizers and DEP prepared a mixture of 80 mass% NC and 20 mass% plasticizers. Quantum chemical calculations using the DFT method were therefore performed by the method B3LYP with 6-31G (d,p) basis set. Three types of new energetic plasticizers were synthesized in three steps as seen in Scheme 1.
