trinitrophenol

Recommended Posts

Materials:

 

20 aspirins, (each containing 0.5 grams of acetylsalicylic acid) from the good people at bayer. Purify these using warm acetone.

 

Now what would you need for making this into TNP?

 

140 ml of >95% H2SO4 (sulfuric acid)

20 grams of KNO3 (potassium nitrate)

10 grams of acetylsalicylic acid (ASA)

 

First dissolve the ASA in the sulfuric acid, then add the KNO3. You might want to go easy on the addition of KNO3, because this tends to heat the mixture quite a bit.

 

Though I don't think there is risk for an explosion when the TNP is in solution, but I don't recommend you try to find out!

 

And definately don't complain with me when it blows up in your face, leaving you bleeding and full of acid (ouch). Anyway, once the KNO3 is all added to the acids, you let is cool down nice and easy, not applying extra cooling or anything, and give it an occasional stir, so gasses can escape the liquid. (which should be a nice red by now)

 

Now dump this red liquid (when at lower temperature) in 0.5 liter of ice water. You'll immedialty notice the change if you're not colorblind, it turns nice yellow !!

 

Leave it a bit, with good stirring, so all the yellow TNP comes out, but while keeping the mixture as cold as possible.

 

Then filter this mixture (normal filter paper should be okay when you used enough of ice-water).

 

Don't forget to rinse with as cold as possible water (barely liquid) Not too much, but make sure most of the H2SO4 is rinsed off. Now you can sqeeze this out, and put it in the sun for drying, which is gonna be very difficult if there is still some sulfuric acid present.

 

From 10 grams of ASA, I got 10 grams of TNP, and I did it in 2 steps, so you should be able to get some more out of it

well it will explode

 

well heres another version of the tut more longer though

 

 

 

 

Trinitrotoluene

WARNING:

DO NOT ATTEMPT TO FINISH THIS PROJECT UNLESS YOU ARE FULLY CAPABLE SAFELY EXECUTING THE PROCESSES IN A SAFE ENVIRONMENT! IF YOU CHOOSE TO CONTINUE, READ THE INSTRUCTIONS COMPLETELY THROUGH BEFORE BEGINNING AND HAVE ALL MATERIALS AND TOOLS (INCLUDING SAFETY/EMERGENCY EQUIPMENT) READY FOR USE WHEN OR IF THEY ARE NEEDED. THIS IS NOT A JOKE! USE AT YOUR OWN RISK!!!!!

Preparation of Trinitrotoluene (Three Stages). A mixture of 294 grams of concentrated sulfuric acid (density 1.84) and 147 grams of nitric acid (density 1.42) is added slowly from a dropping funnel to 100 grams of toluene in a tall 600-cc. beaker, while the liquid is stirred vigorously with an electric stirrer and it's temperature is maintained at 30øC to 40øC by running cold water in the vessel in which the beaker is standing. The addition of acid will require from an hour to an hour and a half. The stirring is then continued for half an hour longer without cooling; the mixture is allowed to stand over night in a separatory funnel; the lower layer of spent acid is drawn off; and the crude mononitrotoluene is weighed. One-half of it, corresponding to 50 grams of toluene, is taken for the dinitration. The mononitrotoluene (MNT) is dissolved in 109 grams of concentrated sulfuric acid (d. 1.84) while the mixture is cooled in running water. The solution in a tall beaker is warmed to 50ø and a mixed acid, composed of 54« grams each of nitric acid (d. 1«0) and sulfuric acid (d. 1.84), is added slowly drop by drop from a dropping funnel while the mixture is stirred mechanically. The heat generated by the reaction raises the temperature, and the rate of addition of the acid is regulated so that the temperature of the mixture lies always between 90ø and 100ø. The addition of the acid will require about 1 hour. After the acid has been added, the mixture is stirred for 2 hours longer at 90ø-100ø to complete the nitration. Two layers separate on standing. The upper layer consists largely of dinitrotoluene (DNT), but probably contains a certain amount of TNT. The trinitration in the laboratory is conveniently carried out without separating the DNT from the spent acid.

While the dinitration mixture is stirred actively at a temperature of about 90ø, 145 grams of fuming sulfuric acid (petroleum containing 15% free SO3) is added slowly by pouring from a beaker. A mixed acid, composed of 72« grams each of nitric acid (d. 1«0) and the 15% petroleum, is now added drop by drop with good agitation while the heat of the reaction maintains the temperature at 100-115ø. After about three-quarters of the acid has been added, it will be found necessary to apply external heat to maintain the temperature. After all the acid has been added (taking 1 « to 2 hours), the heating and stirring are continued for 2 hours longer at 100-115ø. After the material has stood overnight, the upper TNT layer will be found to have solidified to a hard cake, and the lower layer of spent acid to be filled with cdata bstals. The acid is filtered through a Buchner funnel (without filter paper), and the cake is broken up and washed with water on the same filter to remove excess of acid. The spent acid contains considerable amounts of TNT in solution; this is precipitated by pouring the acid into a large volume of water, filtered off, rinsed with water, and added to the main batch. All the of the product is washed three or four times by agitating it vigorously with hot water under which it is melted. After the last washing, the TNT is granulated by allowing it to cool slowly under hot water while the stirring is continued. The product, filtered off and dried at ordinary room temperature, is equal to a good commercial sample of crude TNT. It may be purified by dissolving in warm alcohol at 60ø and allowing to cool slowly, or it may be purified by digesting with 5 times its weight of 5% sodium hydrogen sulfite solution at 90ø for half an hour with vigorous stirring, washing with hot water until the washings are colorless, and finally granulating as before. The product of this last treatment is equal to a good commercial sample of purified TNT. Pure ALPHA-TNT, melting point 80.8ø, may be procured by recrystallizing this material once from nitric acid (d. 1.42) and once from alcohol.

Well, that's it... AND REMEMBER MY WARNING!
