ABSTRACT Process for the production of guanidine nitrate from urea and ammonium nitrate The present invention provides a process for the production of guanidine nitrate by the reaction of urea and excess ammonium nitrate in the presence of a silicon dioxide catalyst at an elevated temperature, wherein the molten reaction mixture containing the dispersed catalyst is passed in a cycle, a branch current of the reaction mixture is continuously separated off by filtration in such a manner that the catalyst remains in circulation and consumed urea and ammonium nitrate are supplemented corresponding to the removal of the product.
