Abstract: The present invention relates to a device for carrying out continuous-flow chemical reactions under pressure or high pressure using a cascade of perfectly stirred Gas-Liquid-Solid reactors, and to the use of these devices for the implementation of such reactions. The device comprises a cascade of interconnected autoclave reactors. The reactors of the cascade are of different volumes and are provided with means allowing them to be controlled individually in a completely independent manner. The cascade of reactors comprises at least two reactors of different volumes, increasing or decreasing in the fluid flow direction.

Abstract: A continuous paracetamol preparation method, including a nitration step or a nitrosation step to obtain p-nitrophenol or p-nitrosophenol respectively. P-nitrophenol or p-nitrosophenol can then be converted into paracetamol by hydrogenation, followed by acylation. This continuous paracetamol preparation method makes it possible to obtain paracetamol with a very good regioselectivity and excellent yields.

Abstract: The present invention relates to a Micro-Free Flow Electrophoresis chip for analyzing or separating a sample including a pile (1) comprising at least two plates (2A, 2B), a sheet (3) uniformly disposed between the two plates (2A, 2B), clamping means, each sheet (3) comprising at least two inlets (11) for entry and at least one outlet (12) for exit of a first fluid electrode and a second fluid electrode, the first and second fluid electrodes applying an electric field to a separation chamber (31).
