Identification

Acetone peroxide (triacetone triperoxide, TATP) is a cyclic trimeric organic peroxide, a condensation product of acetone and hydrogen peroxide. Belongs to the class of primary explosives that are highly sensitive to impact, friction and temperature. Below are only the passport physico-chemical and hazardous characteristics of the substance from the primary dump; information about synthesis, methods of preparation or use is not provided.

Hazardous properties

A highly volatile compound, it decomposes according to an entropically favorable mechanism with the formation of four molecules of the gas phase; Decomposition products include acetone and hydrogen peroxide. Sensitive to shock, temperature and friction when dry; the source states that the substance should be stored under water when not in use and that it sublimes at room temperature.

Safety Information

The primary data source for this item contains primarily general information about the handling of peroxide explosives and recommendations from law enforcement authorities, not related to the physical and chemical data sheet for a specific lot; These sections are not included in the description as they are not characteristics of the product.

Analytical and regulatory significance

Due to the absence of a nitro group, weak UV absorption and low density, the substance is poorly detected by standard methods for detecting explosives, while its vapor pressure is orders of magnitude higher than that of TNT, which determines the specifics of the development of detectors for its vapors. For this reason, the compound is produced by certified manufacturers as an analytical reference standard (for example, as a solution of known concentration in acetonitrile) for calibration of detection equipment and forensic analysis. The precursors for its production - acetone and hydrogen peroxide - are included in the list of substances with limited retail circulation in many countries, including the European Union and the United States. Regulatory measures are not aimed at the compound itself, but at controlling the availability of the starting household reagents from which it can be produced in a homemade way.
