Oxyliquit

A liquid- air explosives (English: Liquit Oxygen Explosive ) is a mixed explosives from liquid oxygen or liquid air and a mostly organic reducing agent. The explosive was known under the trade names Oxyliquit, Marsit and Kowastit especially at the beginning of the 20th century.

History

Under the name Oxyliquit 1895 Carl von Linde developed an explosive from the obtained by the " Linde process " mixture of oxygen and nitrogen in the ratio 1:1. After the first tests and blasting operations about the construction of the Simplon Tunnel in 1899 and 1900 in the mine Penzberg the industrial use of liquid air explosives rested first. After the oxygen content of the liquid air increases and the production costs could be lowered, German and French researchers employed from 1912/13, again with more liquid air explosives.

Oxyliquit found for civil and military purposes, especially in Germany paragraph. Liquid air explosives was not only in mining, but - because of the difficulty during the First World War import conditions eg given also for military use more attention - for nitroglycerin. Among other things, the then Marsit Society reported in Berlin -Charlottenburg for the liquid -air blasting Marsit and Kowatsch and Baldus for Kowastit German and foreign patents. In France at that time Jacques- Arsène d' Arsonval researched and Georges Claude at liquid air explosives.

Properties

As a reducing agent, various porous, absorbent materials can be used, for example, carbon powder, or wood dust, but also impregnated with hydrocarbons kieselguhr. The separate components can be transported relatively safe and do not fall under the Explosives Act. Liquid air explosives are usually mixed just before use. Evaporation of the oxygen they are again relatively quickly harmless. This fact makes it difficult but at the same storage and transport of liquid air explosives and the economic use of a larger scale.

The detonation velocity is 3-5 km · s -1.
