Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
73 words
A method of forming an explosive mixture of ammonium nitrate and ethylenediamine dinitrate which comprises: (a) combining ethylenediamine and a stoichiometric excess of ammonium nitrate, said ammonium nitrate being present in an amount to form, after reaction of said ethylenediamine therewith, a mixture of ammonium nitrate and ethylenediamine dinitrate; and (b) reacting said ethylenediamine with the stoichiometric portion of said ammonium dinitrate to form said explosive mixture of ammonium nitrate and ethylenediamine dinitrate.
Claim 2
Independent Claim
73 words
A method of forming an explosive mixture of ammonium nitrate and ethylenediamine dinitrate which comprises: (a) combining ethylenediamine and a stoichiometric excess of ammonium nitrate, said ammonium nitrate being present in an amount to form, after reaction of said ethylenediamine therewith, a mixture of ammonium nitrate and ethylenediamine dinitrate; and (b) reacting said ethylenediamine with the stoichiometric portion of said ammonium dinitrate to form said explosive mixture of ammonium nitrate and ethylenediamine dinitrate.
Claim 3
Dependent Claim
26 words
The method of claim 1 wherein the mixture of step (b) is heated to form a uniform melt and thereafter cooled to solidify said uniform melt.
Claim 4
Independent Claim
18 words
The method of claims 1 or 2 wherein said explosive mixture of step (b) is an eutectic mixture.
