2,4,6-Trinitro-m-Phenylenediamine is very similar to TNT in both its explosive properties and chemical structure. This substance has gone by the name of 2,4,6-trinitro-1,3-diaminobenzene; 2,4,6-trinitrophenylenediamin-(1,3) in German; and 2,4,6-trinitrometaphenylenediamin in French. It was first prepared in 1884 by E. Nölting and A. Collin from esters of styphnic acid and ammonia. Many other procedures were tried over the years with different starting compounds until C.F. van Duin and B.C.R. van Lennep compiled all the others data around 1920 and developed the lab that I have reproduced here.
|ammonium hydroxide||200-mL beaker|
|ethyl alcohol||graduated cylinder|
Mix 10 g of finely pulverized trinitro-m-anisidine (or trinitro-m-phenetidine) with 80 mL of 24% ammonium hydroxide in a 200-mL beaker. Allow the mixture to stand for 24 hours at room temperature, shake frequently. Filter the solution to collect the precipitate, wash it with water to remove any ammonia, and boil with ethyl alcohol to remove any non-reacted trinitro-m-anisidine or trinitro-m-phenetidine. You will need a graduated cylinder for measuring liquids, and a stirring rod or magnetic stirrer for mixing.
