@X083@X05.@X0840 @X03 NITROGEN TRICHLORIDE
@X08Nitrogen trichloride@X05,@X08 also known as chloride of azode@X05,@X08 is an oily yellow
liquid@X05.@X08 It explodes violently when it is heated above 60 degrees celsius@X05,@X08 or
when it comes in contact with an open flame or spark@X05.@X08 It is fairly simple to
produce@X05.@X08
1@X05)@X08 In a beaker@X05,@X08 dissolve about 5 teaspoons of ammonium nitrate in water@X05.@X08
Do not put so much ammonium nitrate into the solution that some of it
remains undissolved in the bottom of the beaker@X05.@X08
2@X05)@X08 Collect a quantity of chlorine gas in a second beaker by mixing hydrochloric
acid with potassium permanganate in a large flask with a stopper and glass
pipe@X05.@X08
3@X05)@X08 Place the beaker containing the chlorine gas upside down on top of the
beaker containing the ammonium nitrate solution@X05,@X08 and tape the beakers
together@X05.@X08 Gently heat the bottom beaker@X05.@X08 When this is done@X05,@X08 oily yellow
droplets will begin to form on the surface of the solution@X05,@X08 and sink down
to the bottom@X05.@X08 At this time@X05,@X08 remove the heat source immediately@X05.@X08
Alternately@X05,@X08 the chlorine can be bubbled through the ammonium nitrate
solution@X05,@X08 rather than collecting the gas in a beaker@X05,@X08 but this requires
timing and a stand to hold the beaker and test tube@X05.@X08
The chlorine gas can also be mixed with anhydrous ammonia gas@X05,@X08 by gently
heating a flask filled with clear household ammonia@X05.@X08 Place the glass tubes
from the chlorine@X05-@X08generating flask and the tube from the ammonia@X05-@X08generating
flask in another flask that contains water@X05.@X08
4@X05)@X08 Collect the yellow droplets with an eyedropper@X05,@X08 and use them immediately@X05,@X08
since nitrogen trichloride decomposes in 24 hours@X05.@X08
