Ether, transport (2)



Ether-air mixtures are easily combustible, explosive and therefore keep away from sources of ignition. However, diethyl ether and similar substances may become dangerous on long term storage. These hazards caused by organic peroxides and accidents caused by them have been known for a long time, but they are forgotten again and again. In the list of substances that led to accidents, the peroxides ranked 11th in 1985 with 1.5% of all events. In the Organikum of 1963 it is especially feared ether peroxides, which are e.g. from ethyl ether, diisopropyl ether, tetrahydrofuran and dioxane on standing, are easily formed in air and light. The first etheric explosion in the Charité Ferdinand Sauerbruch experienced in 1937 in the scabbing of a lung with a cautery.


Cave: Organic peroxides are among the very dangerous substances! In case of unusual viscosity or crystal formation in the bottle or on the closure do not move and do not open! Peroxides can be tested by adding 2 ml of glacial acetic acid and potassium iodide to 1 ml of ether / isopropanol / butanol. Forming iodine indicates peroxides.
