A method of treating substances, bodies, elements, chemical compounds or microorganisms, in the form of a powdered solid, of a fluid or of comminuted solid particles in a carrier fluid with a view to promoting and/or facilitating a physical transformation and/or chemical reaction involving said substances consists in causing at least one of the substances, for example with the assistance of pressure means, to circulate through a plurality of circuits provided with respective whistleforming means in which the substance is caused to vibrate at a frequency equal to or higher than that of sound whereby to apply to the substance a vibratory energy which causes its dispersion into highly-divided particles, the circuits opening into a common reaction chamber in which the sound- or ultrasonic-waves generated by the substance are propagated whereby the highly-divided particles are subjected in the chamber to the vibratory energy produced by the other circuits or a portion thereof thereby applying a stirring action to the particles and further subdividing them. The physical transformation and/or chemical reaction within the reaction chamber can be carried out either in a gaseous medium, in a liquid medium or in vacuo and may be accelerated by subjecting the substances involved to an auxiliary form of energy. The method may be used to divide a solid to produce an aerosol or a hydrosol. The chemical reaction within the reaction chamber may take place in the presence of a catalyst. A device for carrying out the method comprises a container 1 the bottom 2 of which is formed with a plurality of ducts provided with nozzles or cavities constituting whistles 3 through which one or more fluids may be fed under pressure so as to be emitted as sonic- or ultrasonic-jets into the container. The whistles may be of cylindrical or toroidal shape. The material of the whistles may be flexible. In a modification, the device comprises two parallelepipedic plates the opposed faces of which are formed with whistles, the plates being either parallel or inclined to one another. In another modification, the device comprises a body of revolution e.g. a cylindrical core associated with a reflector or a cylindrical core surrounded by a frusto-conical member. In a further modification, adjacent whistles are set in different directions. In another modification a number of whistles are rendered inoperative by means of a slidable piston or valve. The piston may be replaced by a rotary sleeve having slots of different lengths. The device may form part of a saponification plant, Fig. 10 (not shown), or of an esterification plant, Fig. 11 (not shown).
