STABILITY OF UNSYMMETRICAL DIMETHYLHYDRAZINE(UDMH

Abstract

This research studying the stability of unsymmetrical dimethyl hydrazine (UDMH) usedin many uses. This material unstable against different variable such as heat and oxygen gas present in theair. Results refers that the increases of temperature and oxygen presenting affecting on the stability of thismaterial by exiting oxidation reactions. Oxidation of this material for six months decreases itsconcentration approximately to the half. According to the conclusions obtained from the laboratory tests,we find that the unsymmetrical Dimethylhydrazine (UDMH) is directly affected by oxygen in theatmosphere and the increase of temperature leads to activating the oxidation reactions and this forces usto store the fuel inert atmosphere (Nitrogen, Helium or Argon) at low temperature as possible.
