Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
25 words
A method according to claim 1 wherein the amount of 2,2'', 4, 4'', 6,6''-hexanitrostilbene is not greater than 2 percent by weight of the 2,4,6-trinitrotoluene.
Claim 2
Dependent Claim
26 words
A method according to claim 2 wherein the amount of 2,2'', 4, 4'' , 6,6''-hexanitrostilbene is not greater than 0.5 percent by weight of the 2,4,6-trinitrotoluene.
Claim 3
Dependent Claim
58 words
A method according to claim 3 and comprising the steps of: heating the melt containing 2,4,6-trinitrotoluene and 2,2'', 4, 4'', 6,6''-hexanitrostilbene at about 100* C. with stirring until a substantially homogeneous mass is obtained, permitting the melt to cool until it stiffens, reheating the melt to a temperature immediately below 85* C., and permitting the melt to cool.
Claim 4
Dependent Claim
19 words
A method according to claim 1 wherein an aromatic nitro compound soluble in 2,4,6-trinitrotoluene is added to the melt.
