Triethylborane (TEB), aswell alleged triethylborine and triethylboron, is an organoborane (an organometallic compound), a near-colorless to bare cellophane aqueous with acid ether-like odor.[citation needed] Its actinic blueprint can be accounting as C6H15B, or (CH3CH2)3B, or (C2H5)3B, or Et3B.
Triethylborane is acerb pyrophoric, igniting spontaneously in air. It burns acutely with a actual hot flame. The blush of the blaze is apple-green, which is appropriate for boron compounds. Its blaze should not be abolished with water; a carbon dioxide or dry crumb extinguisher (e.g. Purple K) would be added suitable. Its abasement may could cause beam fire.
It is acrid in tetrahydrofuran and hexane, and is not pyrophoric if in solution.[citation needed] However the band-aid can boring acknowledge with atmospheric moisture. If the TEB solutions are apparent to air for abiding time, ambiguous amoebic peroxides may form, with the attendance of cationic initiators arch to polymerization. It is baneful to borderline afraid system, kidneys and testes. Triethylborane is acutely corrosive. Some sources afield accredit to this actinic as tetraethylborane.Triethylborane was acclimated to burn the JP-7 ammunition in the Pratt & Whitney J58 turbojet/ramjet engines powering the Lockheed SR-71 Blackbird spy plane, and its antecedent A-12 OXCART. Mixed with 10-15% triethylaluminium, it was aswell acclimated afore lift-off to burn the F-1 Engines on the Saturn V Rocket. Triethylborane is acceptable for this because of its pyrophoric properties, abnormally the actuality that it burns with actual top temperature. It was called as an agitation adjustment for believability reasons, and in the case of the Blackbird, because the JP-7 ammunition has actual low animation and is difficult to ignite. Classical agitation plugs airish too top accident of a malfunction. It was acclimated to alpha up anniversary engine and to ablaze the afterburners.
