Abstract
An improved method for producing known primer constituents lead styphnate and barium nitrate, in situ, plus water. The process is carried out by reacting effective amounts of trinitroresorcinol (TNR), with barium hydroxide, or barium carbonate, and lead nitrate in water.

A method of forming a lead styphnate compound plus an oxygen-donating compound, in situ, for use in a priming mix, said method comprising reacting trinitroresorcinol with an oxygen-bearing compound selected from the group consisting of barium oxide, barium hydroxide compounds, barium carbonate, or mixtures thereof, in the presence of lead nitrate.
A method of forming a lead styphnate compound plus an oxygen-donating compound, in situ, for use in a priming mix, said method comprising reacting trinitroresorcinol with an oxide, hydroxide or carbonate of a metal selected from the group consisting of barium in the presence of lead nitrate.
A method of forming a lead styphnate compound plus an oxygen-donating compound, in situ, for use in a priming mix, said method comprising reacting trinitroresorcinol with an oxygen bearing compound selected from the group consisting of barium oxide, barium hydroxide compounds, barium carbonate, or mixtures thereof, in the presence of lead nitrate and water.
A method of forming a lead styphnate compound plus an oxygen-donating compound, in situ, for use in a priming mix, said method comprising reacting trinitroresorcinol with an oxide, hydroxide, or carbonate of a metal selected from the group consisting of barium in the presence of lead nitrate and water.
A method of forming an intimate admixture of a lead styphnate compound and barium nitrate in situ, for use in a priming mix, said method comprising reacting trinitroresorcinol with a barium hydroxide compound in the presence of lead nitrate and water.
A method of forming an intimate admixture of a lead styphnate compound and barium nitrate, in situ, for use in a priming mix, said method comprising reacting trinitroresorcinol with a barium compound selected from the group consisting of barium oxide, barium hydroxide compounds and barium carbonate in the presence of lead nitrate and water.
A method of forming a priming mix comprising the steps of:
- (a) reacting trinitroresorcinol with an oxygen bearing compound selected from the group consisting of barium oxide, barium hydroxide compounds, barium carbonate and mixtures thereof, in the presence of lead nitrate and water to form, in situ, a mixture of a lead styphnate compound and an oxygen donating compound;
- (b) adding to said mixture effective amounts of a sensitizer, a booster, and a fuel;
- and
- (c) mechanically blending the resulting mixture to form a relatively homogeneous mix of ingredients.
