Abstract: The present invention relates to a process for producing a water cleavage product, a water cleavage product thus produced, a process for producing at least one water cleavage secondary product, a water cleavage secondary product thus produced and the use of a multi-fluorinated alcohol compound for the extraction of at least one water cleavage product from an aqueous phase.

Abstract: Economic production of solid particles from a liquid medium, which involves the liquid medium being formed as a cohesive liquid jet and being divided into defined sections (9′) by a dividing device which is moved continuously in one direction in a cutting plane (8) is achieved, according to the invention, while minimizing cutting or spray losses caused by the dividing of the liquid jet (9), by the fact that a plurality of liquid jets (9) are provided, beneath which a common dividing device (5) is arranged, the liquid jets (9) being inclined with respect to the direction of movement of the dividing device (5) in such a way that each of the liquid jets (9) forms an acute angle (&bgr;) with the direction of movement of the dividing device (5).
