NEW THERMALLY STABLE EXPLOSIVE
It is known that there is a lack of thermally stable explosives showing at the same time a low solubility
in water, longevity and compatibility as well as an easy and cheap way of synthesis.
A number of such explosives of better thermal stability than conventional explosives, e.g. TNT and RDX, have been developed, but their widespread use has been hampered by the lack of availability due to their high costs. Accordingly there is a strong demand for new explosives with high energy and low sensitivity in order to overcome these problems.
The present innovation provides asynthesis of a new explosive substance called TKX-55 (5,5‘-bis(2,4,6-tri- nitrophenyl)-2,2‘-di(1,3,4-oxadiazole)), which indicate that it has a tremendous potential to replace explosives, like PYX and HNS.
The present invention provides a convenient and reliable thermally stable explosive compound, which is especially important for deepoil and gas exploitation where thermally stable perforators for oil and gas wells are required, and in space exploration, e. g. for achieving stage separation in space rockets.
- convenientand cost-effective synthesis (favorable educts)
- no time-consuming steps involved in isolation and purification (intermediates and product precipitates in the reaction solution)
- easy to handle
- achieving high yields
- shows high selectivity
- low production costs
- eco-friendly, because TKX-55 is not soluble in aqueous solutions
- does not contain any acidic protons
The novel explosive is characterized by its extraordinary chemical advantages, like high thermal sta- bility and insolubility in water, but has nevertheless eco-friendly features, which all together makes a considerable potential for large-scale manufacture and future use.
