In the present study, interaction of DMAZ and TEMED has been investigated within limitations density functional theory at level B3LYP/6-31++G(d,p). is an explosive material but it also oxidant constituent some hypergolic systems. or TEMEDA acts as partner DMAZ. The findings reveal that in absence any reaction, mainly electrostatic nature, no bond cleavages new formations happen. variations are ...
2-Dimethyl amino ethyl azide (DMAZ) has attracted much attention as a suitable liquid fuel replacement for monomethyl hydrazine (MMH) and unsymmetrical dimethyl hydrazine (UDMH) in propellant systems because, in contrast to these fuels, it is noncarcinogen. In this research, performance, and ignition delay time of DMAZ were studied with common liquid oxidizers such as inhibited red fuming n...
Dimethylaminoethyl azide (DMAZ) is a good candidate fuel for hydrazine derivatives in aerospace industries. DMAZ is synthesized via reaction of dimethyl aminoethyl hydrochloride with sodium azide in aqueous solution, which, in next step, by adding of concentrated sodium hydroxide, organic phase is separated. Therefore, the determination of amount of unextracted DMAZ in aqueous phase (wastewater...
Abstract Dimethyl amino ethyl azide (DMAZ) is a good replacement for hydrazine derivatives in aerospace industries. DMAZ is in organic phase with a concentration of at least 95%. It is necessary to purify DMAZ to high concentrations. Several routs have been suggested for this purpose, in which distillation is a practical and applied method. Thermal sensitivity of DMAZ leads to conducting the p...
Dimethyl amino ethyl azide (DMAZ) is a good replacement for hydrazine group in space programs. This chemical was purified from water (1) + DMAZ (2) mixture in sub-atmospheric distillation column due to thermal sensitivity of DMAZ. For designing of the column, it is necessary to have vapor-liquid equilibrium data. In this article, T-x,y and y-x diagrams were obtain...
دی متیل آمینواتیل آزید (dmaz) نوعی سوخت مایع نوین است که جایگزین مناسبی برای مشتقات هیدرازینی در صنایع هوا فضا به شمار می آید. این ماده از واکنش دی متیل آمینو اتیل هیدروکلرید و سدیم آزید در محیط آبی سنتز میشود که در مرحله بعد با افزایش محلول سود بصورت فاز آلی جداسازی می گردد. تعیین مقدار محصول استخراج نشده در فاز آبی (پساب) در مطالعه راندمان محصول و همچنین ارزیابی میزان آلودگی زیست محیطی امری ض...
Liquid fuel dimethyl aminoethyl azide (DMAZ) has been attended by many researchers as a new green fuel in recent years. Ssynthesis of the fuel has led to a process contains dehydration of DMAZ as a highlighted section. In this study, dehydration of DMAZ/water solution has been investigated by using four different zeolite membranes as HSOD, NaA, LTT and NaX that cover different pore sizes. Many ...
2- Azido N, N-Dimethyl Ethane-1-Amine, well-known as a DMAZ, is considered as a new green liquid fuel and a good alternative to hydrazine fuels because of its high performance while being non-carcinogenic. But no DMAZ energetic complex has been synthesized and reported yet. In this study, a new energetic complex of copper (II) nitrate and DMAZ ligand was synthesized for the purpose of increasin...
