An explosion occurred during the chlorination of S-ethylisothiourea sulfate and formamidine thiolacetic acid-hydrochloric acid. Formation of spontaneously explosive nitrogen trichloride was the suggested cause.
Reacts explosively or forms explosive compounds with many common substances such as acetylene, ether, turpentine, ammonia, fuel gas, hydrogen and finely divided metals.
With cobalt (II) chloride and methanol: During the preparation of cis-dichlorobis(2,2'-bipyridyl)cobalt(III) chloride ... passage of chlorine into an ice cold solution of cobalt chloride, bipyridyl and lithium chloride in methanol soon caused an explosion followed by the ignition of the methanol inside the reaction vessel.
With aluminum: Corrosive failure of a vaporizer used in manufacture of aluminum chloride caused liquid chlorine to contact molten aluminum. A series of explosions occurred.
With amidosulfuric acid: Chlorination of aq sulfamic acid led to an explosion from formation of nitrogen trichloride.
With butyl rubber and naphtha: Chlorination of butyl rubber in naphtha with chlorine-nitrogen mixtures may lead to explosion if nitrogen contents below 77% or chlorine contents above 16% are used.
With chlorinated pyridine and iron powder: An explosion occurred during the preparation of iron(III) chloride from iron powder and chlorine gas in a chlorinated pyridine solvent. This was attributed to formation of iron(II) chloride, its interaction with the solvent to give iron(III) chloride, then reduction of the latter by iron to iron(II) chloride. The exotherm and incr evolution of hydrogen chloride caused the reactor to fail.
