Abstract: The present invention relates to a system for the conversion of chemical structures where the system contains a reservoir reactor having a first lower zone where high solubility of at least one salt in a solvent is maintained under first conditions of pressure and temperature, a second upper zone for precipitating at least one salt under second conditions of pressure and temperature, means for maintaining the first and second conditions of temperature and pressure, means for generating ultrasound, and means for forming a solvent in the lower part of the reservoir reactor.

Abstract: The present invention relates to a process for converting chemical structures, that is to say a process for the conducting of chemical reactions in a fluid under pressure and at temperature in a supercritical fluid in particular, containing a solvent and at least one electrolyte such as a salt, in which reactive species are generated in situ by electrolysis. According to the invention, the fluid flows upwards in a reservoir reactor crossing through a first lower electrolysis zone with high salt solubility and a second upper zone in which the salts precipitate, then the fluid free of salt is evacuated at the upper part of said reservoir reactor and directed into a second tubular reactor to reach the desired stage of advancement of the conversion.

Abstract: Chemical transformation of complex chemical structures in a supercritical medium.The transformation of one or more chemical structures (20) involves at least one reduction reaction in a solvent (22) in the supercritical state.Application to the destruction of dangerous products, the treatment of industrial effluents and natural products and the modification of molecular structures.
