Unsymmetrical dimethylhydrazine (UDMH) is a high energy propellant used in a large volumes as a fuel for intercontinental ballistic missiles (ICBM). UDMH is also used in the space shuttle program and other aerospace operations. In addition, UDMH is a degradation product of Daminozide which is a pesticide commonly used to improve the size, colour development and storage features of apples and peaches. A literature survey has revealed that several different analytical techniques have been used for the detection of hydrazine and its alkyl derivatives. Examples include coulometry, potentiometry, titration, colorimetry, dosimetry, fluorescence, mass-spectrometry, ion-mobility spectrometry, gas chromatography, and liquid chromatography. The gas chromatography/mass spectroscopy (GC/MS) method of UDMH analysis reportedly shows promise but has not yet been developed sufficiently. This paper reports the results of the development of new extraction methods for UDMH from soil and water by reacting it with different aromatic aldehydes (benzaldehyde, 4-chlorobenzaldehyde, 4-dimethylaminobenzaldehyde, furalaldehyde and terepthaladehyde). A comparison will be made between the developed UDMH analytical methods and those reported in the literature.
