  7. Abstract:
  8. Green chemistry seeks to reduce or eliminate the use of hazardous substances in the chemical industry through the development of new products and processes .The replacement of harmful, widely used solvents and reagents is a key part of this approach. Supercritical fluid such as CO2 or water are good solvent for replaceement Exchange reactions involving the displacement of hydrogen bonded to carbon by deuterium are of interest in a broad variety of disciplines, such as the preparative chemistry of isotopically labeled materials, fundamental studies of carbonehydrogen bond activation processes, and studies of the nature of catalysts. The low cost of water and its environmental friendliness are incentives for the growing interest in water as an effective medium for organic reactions that can take advantage of favorable changes in the chemical and physical properties of water at high temperatures and pressures. Water at high temperature and pressure exhibits some characteristic features that are significantly different from those of ambient water. The advantages of sub- and supercritical water for the application purposes are related to such drastic changes in its chemical and physical properties as a solvent
