Title: Improvements in the manufacture of guanidine nitrate
Inventor: ROBERTS ELWYN
Filed: 1958-05-06
Abstract: Ammonium carbamate is formed as a byproduct during the preparation of guanidine nitrate by heating urea and ammonium nitrate in the presence of silica gel (see Group IV(b)).  The ammonium carbamate is given off in vapour form and may be converted to urea for recycling.ALSO:Guanidine nitrate is prepared by reacting urea and ammonium nitrate in approximately equimolar proportions in the presence of silica gel catalyst to yield a reaction product containing some unreacted ammonium nitrate, adding urea (with or without ammonium nitrate) to adjust the molar proportion of ammonium nitrate to urea to 65:35 to 30:70 so that the melting point of the ammonium nitrate-urea mixture is below 100 DEG C., and then crystallising out guanidine nitrate.  With the molar proportion of ammonium nitrate to urea of 50:50 to 45:55, the melting point is below 60 DEG C.  The guanidine nitrate is removed and may be purified by recrystallisation from water, the mother liquors after dehydration being recycled to the beginning of the process.  The silica gel may be contained in an open-mesh basket which is slowly rotated in the fused reaction mixture.  The preferred reaction temperature is about 180 DEG C.  Ammonium carbamate is removed from the reaction as vapour and may be converted to urea which is recycled.  A small amount of ammelide is obtained as an insoluble by-product.
