An oxygen scavenging composition is set forth in which the composition contains a protic solvent hydrolysable halogen compound which is deposited upon oxidizable metal particles, contacting the metal with an essentially moisture free liquid containing the protic solvent hydrolysable halogen compound and then evaporating, if necessary, any remaining solvent from the solid. Also set forth are walls of containers and preforms which contain this composition.
L'invention concerne une composition désoxygénante qui contient un composé halogène hydrolysable par solvant protique qui est déposé sur des particules métalliques oxydables. Selon l'invention, on met en contact le métal avec un liquide, pratiquement exempt d'humidité, contenant le composé halogène hydrolysable par solvant protique, puis on fait évaporer, si nécessaire, tout solvant résiduel hors du solide. L'invention concerne également des parois de contenants et des préformes contenant cette composition.
