Abstract

Unsymmetrical dimethyl hydrazine (UDMH) is a strong propellant, which due to its very good physical properties and high power of repellency has been utilized as a liquid fuel for fighter jet engines for so many years. There are different methods for production of this material.One of the more efficient ones which results in higher yields compared to others is the CATALYTIC HYDROGENATION of Nitroso Dimethylamine (NDMA). In this work hydrogenation of NDMA to UDMH on a 5% Pd/C in aqueous solution of NDMA was studied experimentally. Experiments were carried out in a Semi-batch three phase STR reactor under constant pressure and temperature in the range of 40 to 70°C, pressures of up to 15 bar and an NDMA concentration of 40 to 70 wt%. Products were analyzed using the Gas Chromatographic (GC) technique. Effects of temperature, pressure and NDMA concentration on NDMA conversion and yield of UDMH product in the presence of undesired dimethylamine (DMA) were studied and the optimum conditions for the selective production of UDMH were sought. A kinetic model based on the general form of the Langmuir-Hinshelwood (LH) equation was developed. Further, it was assumed that the hydrogen adsorption is dissociative and non competitive. Comparison with experimental data showed that the Eley-Rideal (ER) model has very good predictive capabilities relative to LH rate equation and therefore, it was selected for further study. Based on this relation the reaction parameters for UDMH and DMA rate equations were estimated through the non linear regression method and activation energies of UDMH and DMA reactions were determined to be 15.97 and 64.98 KJ/mol, respectively.
