Azeotropic and azeotrope-like compositions of methyl iodide and at least one fluorocarbon or hydrofluorocarbon such as 1,1,1,3,3-pentafluoropropane (HFC-245fa). The compositions are present as a gas, at temperatures of about 30°C or below. The inventive compositions serve as a non-ozone-depleting gaseous fumigant which is useful in a variety of applications, in place of methyl bromide. These compositions serve as a drop-in replacement for gaseous methyl bromide, providing the benefits of a methyl iodide fumigant while also utilizing existing methyl bromide equipment.
L'invention concerne des compositions azéotropes, ou similaires à un azéotrope, d'iodure de méthyle et d'au moins un fluorocarbure ou un hydrofluorocarbure tel que du 1,1,1,3,3-pentafluoropropane (HFC-245fa). Les compositions sont présentes en tant que gaz, à des températures d'environ 30° ou inférieure. Les compositions selon l'invention servent de fumigant gazeux ne détruisant pas la couche d'ozone, ce qui est utile dans diverses applications, à la place du bromure de méthyle. Ces compositions servent d'équivalent exact pour du bromure de méthyle gazeux, en procurant les avantages d'un fumigant à l'iodure de méthyle tout en utilisant également l'équipement existant pour le bromure de méthyle.
