Abstract

The mixture obtained by reaction of amine with calcium nitrate in water environment at the temperature of 60 degrees C in presence of carbon dioxide, containing correspondent alkyl substituted ammonium nitrate, or possibly deprived of precipitated calcium carbonate, is mixed and enriched with initial amine, calcium nitrate and once through calcium cyanamide. The reaction mixture is maintained for a period of 1 to 2 hours at a temperature of 60 to 70 degrees C, then it is enriched with carbon dioxide and in hot condition it is deprived of the precipitated calcium carbonate. After cooling the crystallized alkyl substituted guanidine nitrate of the following general formula is isolated from it: R<1> (R<2>) N - C(NH) - NH2 . HNO3, where R<1> means hydrogen or C2 to C4 - alkyl and R<2> means C2 to C4 - alkyl. The remaining water part, containing the corresponding alkyl substituted ammonium nitrate and residua of the resulting dissolved reaction product are returned to another cycle of reaction with calcium cyanamide. The solution can be used for production of some low-toxic insecticides.
