TATP or Not TATP? - That is the Question
A friend with a doctorate in chemistry sent me the following:
"According to the official government story, TATP (triacetone triperoxide) was the explosive these conspirators were planning to manufacture aboard the airliners.
"This story is not plausible for a number of reasons, but let's take a quick look at just enough of the science so as not to provide anybody with a guide to making an actual bomb: TATP is made from hydrogen peroxide solution, acetone and sulfuric acid. The reaction can be carried out with just about any concentration, but is best done with concentrated solutions of both peroxide and acetone.
"The peroxide and acetone can be pre-mixed, but the acid must be added, a drop at a time, to the solution, all the while continuously stirring it and keeping it continuously chilled. This step of the process will take several hours, during which the fumes given off will be substantial and quite overpowering, thus a lab-quality air evacuation system is required. (ES: right here, the whole idea of a TATP bomb becomes ludicrous. Difficult in a lab, but impossible in an airplane due to the environment - the toilet - and the time requirement.)
"One then must let the resulting solution stand for an extended period at temperatures above the freezing point, but definitely below 10 Celsius (50 Fahrenheit). Above 10 Celsius, the TATP does not form; instead, diperoxide forms, which is so unstable it cannot be worked with. The time required for the reaction to go to completion is at least 24 hours and often several days.
I don't belive there exist such a thing.
The TATP is difficult and must be made in labratories under 10 degree celcius.
uncatalyzed synthesis involved keeping a mixture of acetone and
hydrogen peroxide for 4 weeks at room temperature.

The suspected terrorist using such must be expert on chemistry, or at least more than common knowledge on chemistry to make it.
one forum, called al-Bramj explains to inquirers, in plain language and thorough details, how to make the highly explosive acetone peroxide as a main explosive charge and how to make a detonator from the same substance. The jihadi who posted the instructions was also aware of the precautionary details necessary when handling or mixing the components.
Liquid Explosive Training Manuals Easily Attainable on Jihadi Forums
On November 6 last year, the Sunday Times reported that another Islamist web forum, called Al Firdaws or Paradise contained detailed instructions for making bombs. The site had posted on October 6 a manual which detailed in 80 pages how to make bomb materials in kitchens.

And would it not be easier to use the common dynamite bombs with timer rather than the fancy liquid thing?
