سنتز بایندر پر انرژی- THF BAMO (علمی-پژوهشی)

سنتز ، شناسایی و آنالیز کنفورماسیونی مشتقات جدید بیس هیدروکسی اتیل تترازول به عنوان دی ال های پر انرژی(علمی-پژوهشی)

Tetrazoles and their derivatives are insensitive energetic molecules that can be used in the compounding of the high energy material. Herein, two types of bis hyroxyethyl tetrazole compounds have been synthesized using bisnitrile and sodium azide and via consequent alkylation of the reaction product .The structure of all products have been confirmed by 1HNMR, MASS spectroscopy and elemental...

ساخت پیشرانه دو پایه پر انرژی ap-cmdbجهت تامین محرکه ویژه حداقل 240 sec (علمی-پژوهشی)

سنتز و مشخصه یابی نرم کننده های پر انرژی سازگار با HTPB

Hydroxyl terminated polybutadiene (HTPB) is the most important and versatile binder in composite solid propellant, But the immiscibility of this polymer with traditional energetic plasticizers is a disadvantage limits its application as a binder for compounding of high energy propellant. In this research, two types of energetic plasticizer, 2-ethylhexyl nitrate (2EHN) and 2-ethyl-2-buthyl-1, 3 ...

بررسی سیستم های پلیمری حاوی گروه های پر انرژی تترازول(علمی-ترویجی)

Tetrazoles are cyclic aromatic compounds that include four nitrogens and one carbon atom in one ring .These compounds have many applications in civil and military industries. These compounds can produce great amount of N2 after burning and for this reason they have a little environmental contamination and are considered as green explosive materials. Introduction of tetrazoles in polymeric chain...

LiYbCl4(THF)4

The title compound, di-μ-chlorido-dichlorido-1κ(2)Cl-tetra-kis-(tetra-hydro-furan)-1κ(2)O,2κ(2)O-lithiumytterbium(III), [LiYbCl(4)(C(4)H(8)O)(4)], was prepared by the reaction of YbCl(3)(THF)(3) with LiCl in THF (THF is tetra-hydro-furan). The central motif of the structure is a Yb(μ-Cl)(2)Li ring. The Yb atom is hexa-coordinated to four Cl atoms and two THF mol-ecules oriented in a trans fashi...
