In order to reduce the noble metal palladium dosage in preparation of CL-20 so as its production cost, several carbon supports were prepared successfully using hydrothermal carbonization method absence or presence urea microcrystalline cellulose (MC) source, and corresponding Pd(OH)2/C catalysts fabricated deposition–precipitation method, which showed high activity debenzylation reaction hexabe...
CL-20 is the most energetic conventional explosive available for military use. The over all aim of the high energy material research community is to increase the yield and reduce the cost of CL-20 synthesis. All synthetic methods used to prepare the CL-20, depended on the condensation reaction of benzylamine with glyoxal for the preparation of HBIW intermediate . In the presence of HCOOH cata...
در این کار پژوهشی، برهم کنش آمین حلقوی 12،10،8،6،4،2-هگزا بنزیل 12،10،8،6،4،2-هگزا آزا تترا سیکلو [3،110.5،90.0.5.5] دودکان ، که به عنوان هگزا بنزیل هگزا آزا ایزو ورتزیتان(hbiw) شناخته می شود، با کبالت(ii) بررسی شد. این کمپلکس شدن در سطح جدایی دوفاز صورت گرفت. حضور آنیون هالوژن برای این کمپلکس شدن ضروری است. محلول بی رنگ hbiw در کلروفرم یا دی کلرومتان طی مجاورت با کلرید کبالت(ii) شش آبه جامد، ر...
