Do you, guys wont me to post really good, and of course personally tested sinth. of Tetryl? This substance is the right ingridient to mixtures which you make with AP and other peroxides. Sinth is really simple, not dangerous-except fumes-and you get much, much better results and less dangerous product.
It's so simple as making picric acid. Actually you can use same equipment setup, except you must change one of starting chemicals. At the end you get product which is stabille, does not react with metals and does not form supersensitive salts as picrates are. It's not to impact sensitive, not friction sensitive and - sugar for the last - has VoD 7650 m/sec.
It has good sides of aromatic nitro compounds and good sides of nitramines, without most of inconvenients which making nitramines can have.
Only problem, not to big, is getting a hold of some NN-dimethyl anilyne. It's a stinky, oily liquid which need not be too difficilt to obtain.
There is another way of making it from dinitrochlorbenzene, which I did not personally tested, but it also must work.

Synths for practically every explosive compound ever made are easily available online. Theres no point posting it. THIS is why you never see synths posted here. Mainstream explosives like tetryl have a TON of documentation on them available online. The synths in the textfile section were put there a loooooonnggg time ago... and most would be removed if the regular members here had their way, however the keeper of &TOTSE essentially ignores us.

Its a well documented reaction. As are synthetic routes to its precursor dimethylaniline.

Well- I see. In America it's - so seames - access to info easy. Access to chemicals is more difficult. In Europe, expecially in SE Europe is different. Here is much more complicated to get right, checked info than chems.
We still use books as most reliablle source of info.We do check online - who has computer, but usually we belive in books more, and experienced people advice. It's a lot of nonreliablle info online-not all, but sometimes even maliciously wrong info, like that fire-water was.
Peace!

Well I'm pretty sure that there's at least one patented tetryl synth, and if you don't trust the patents office, you shouldn't trust any of us either.

From the sound of it, you have a synth but don't fully trust it ... I'll be honest here, I've never looked into tetryl so I can't give you a definitive answer, but I'll gladly read through your find and comment on it.

Dimethilaniline is to be disolved in conc. sulfuric acid, 25 g in 360 g, at temperature 25-30 deg C, stirred for an hour. Take 1 ccm in test tube and add a drop of watter. If it remains clear-proceed. If becommes milky heat to 40 deg C., and srirr for a half of hour more. That you can do inside a house.
Then prepare water bath 55-60 deg C. Go outside, to your back yard !! Ad dimethil anilyne sulfate you get in step 1 , slowly,drop by drop to 250 ccm mixed acids (154 g of nitric acid +37 g sulfuric acid-both concetrated, but not fuming) and keep temperature at 55 - 60 deg C and stir. Reaction produces heat - so keep it under 70 deg C and continiue stirring for an hour. Let it cool. Pour in large amount of water and wash to neutral reaction. Than discard all liquid and vacuum filter your tetryl on sintered glas filter. You'll get christals, which tend to form chunks. Either chrush chunks and continiue washing in hot water, or - if you wont practically unlimited stability-recristalize from warm acetone.Take care to keep out of brown fumes.Wear heavy rubber gloves, bexause those fumes penetrate trough, for instance-winter leather gloves and burn your hands. Amount of fumes is much greater then when making picric acid. So you get the best HE I was working with.Simple as that!
That HE you can mix with KNO3 or Ba(NO3)2 and Mg, Al pulv.and CuO, for greater effect

Seems legit ... technically it should be annilinium sulfate but I'd say it's on the level, can't really comment on the factuality though.

The real question is:
I used old, russian WWII process earlier, when I made it,in 1970th which recomanded pouring dimethil anilyne sulphate in yust as conc. nitric acid as possible, in excess, for nitration, and nothing about temperature was mentioned. Process I wrote to your forum is yugoslav 1985 book method. Considering that conc nitric acid is not really easy avaliablle even here, you have to buy reagent grade, no acid from drums any more, cheap and no question if you wont 10 l....
Yugoslav book is promissing better economy of nitrates. Will evrithing be so easy?
