Process for obtaining piracinobutazone, which is characterized essentially by using a solvent of such nature that the first producer that originates in the reaction, monosal, is the only possible result of the entire process due to its insolubility in the solvent, for which reason, the monosal separates spontaneously from the reaction medium, thereby inhibiting any tendency to form a disal, using, as solvent that meets these conditions, an aliphatic hydrocarbon of 5 to 9 carbon atoms, pure form or compound mixture, and, preferably, N-hexane.
