Title (EN) PHOSPHINE EMISSION INHIBITION
(FR) INHIBITION DE L'EMISSION DE PHOSPHINE
Abstract: front page image
(EN)A composition comprising phosphorus and a minor amount of at least one radical inhibitor selected from 4-(p-nitrophenyl-azo)-1-naphthol and mono and fused bi- and tri-cyclic compounds bearing at least a first and a second substituent, the first substituent being selected from hydroxy, mercapto, oxo, thioxo, the second substituent being selected from hydrogen, hydroxy and mercapto when the first substituent is hydroxy or mercapto and from oxo and thioxo, when the second substituent is oxo or thioxo, the second substituent being located on the same ring and ortho or para to the first substituent, other than anthraquinone or a substituted anthraquinone has reduced levels of phosphine emission. Munitions containing the composition as the charge are less susceptible to corrosion.
(FR)La composition décrite, qui sert à réduire les niveaux d'émission de phosphine, comprend du phosphore et une petite quantité d'au moins un inhibiteur de radical choisi parmi du 4-(p-nitrophényl-azo)-1-naphtol et des composés monocycliques et bicycliques et tricycliques amalgamés portant au moins un premier et un second substituants. Le premier substituant est choisi parmi un hydroxy, un mercapto, un oxo, un thioxo. Le second substituant est choisi parmi un hydrogène, un hydroxy et un mercapto, lorsque le premier substituant est un hydroxy ou un mercapto, et entre un oxo et un thioxo, lorsque le second substituant est un oxo ou un thioxo. Le second substituant est situé sur la même chaîne orthogonalement ou parallèlement par rapport au premier substituant, qui est autre que l'anthraquinone ou qui est une anthraquinone substituée. Des munitions contenant une telle composition comme charge sont moins sensibles à la corrosion.
