Abstract: The invention relates to a device for the molecular integration or disintegration of solid, liquid and/or gaseous flowing, entrained and/or countercurrent components by means of cavitation in order to modify, build or disintegrate molecular compounds. The invention allows to obtain stable mixtures from immiscible or difficult-to-mix components or to separate such mixtures. The supercavitation molecular reactor allows to build up or disintegrate or modify, with low expenditure in terms of energy, even complex compounds that so far have not been accessible to modification and/or production or only by very extensive multiple processes and a large amount of technical complexity.
