[ 1 ] - Nano TiO2–H3BO3 as an efficient and recycable catalyst for the synthesis of 5-substituted-1H-tetrazoles
An efficient method for the synthesis of 5-substituted-1H-tetrazoles through the reaction of nitriles with sodium azide using titanium oxide–supported boric acid (TiO2-H3BO3) catalyst was reported. The reactions were carried out at 120 °C and provided the corresponding tetrazoles in good to excellent yields. This method displayed significant advantages ...
[ 2 ] - Facile synthesis of 5-substituted-1H-tetrazoles catalyzed by reusable nickel zirconium phosphate nanocatalyst
5-Substituted-1H-tetrazoles were synthesized by the [3 + 2] cycloaddition of sodium azide with various nitriles in the presence of nickel zirconium phosphate (NiZrP) as an effective heterogeneous catalyst in dimethylsulfoxide at 120 °C. This method has the advantages of good to high yields, simple methodology and easy work-up. The catalyst can be recovered by centrifuging and reused with good y...

Use of plasticizers in the formulation of solid propellants especially double-base solid propellants is inevitable. Double base propellants are composed of nitrocellulose (NC) polymer. Plasticizers cause to increase flexibility, reduce viscosity and glass transition temperature. Energetic azido ester plasticizers are compatible with energetic binders in solid propellants. In this work, five dif...

Abstract In this work the new simple model proposed for predicting the thermal decomposition temperature of energetic nitroaromatic compounds. The results are shown that the optimum elemental composition and several structural parameters have the most effects on this model which is derived by multiple Linear Regression (MLR) approach. The determination coefficient of the model is 0.940 for 29 ...
