Abstract
(EN)
The present invention addresses the problem of providing: a phosphine for fumigation, which effectively suppresses blockage of pipes in a fumigation gas feeding device caused by impurities, and which is unlikely to undergo spontaneous combustion; and a safe phosphine fumigation method for reducing the possibilities of spontaneous combustion and blockage of pipes in a fumigation gas feeding device. This phosphine for fumigation has a P4 content equal to or less than 10 mass ppm and a water content equal to or less than 10 mass ppm. This fumigation method is for fumigating an object to be fumigated, by using a phosphine having a P4 content equal to or less 10 mass ppm and a water content equal to or less than 10 mass ppm.

La présente invention aborde le problème consistant à fournir : une phosphine pour fumigation, qui supprime efficacement le blocage de tuyaux dans un dispositif d'alimentation en gaz de fumigation provoqué par des impuretés, et qui est peu susceptible de subir une combustion spontanée ; et une méthode de fumigation de phosphine sûre permettant de réduire les possibilités de combustion spontanée et de blocage de tuyaux dans un dispositif d'alimentation en gaz de fumigation. Cette phosphine pour fumigation a une teneur en P4 inférieure ou égale à 10 ppm en masse et une teneur en eau inférieure ou égale à 10 ppm en masse. Cette méthode de fumigation est destinée à la fumigation d'un objet à fumiger, en utilisant une phosphine ayant une teneur en P4 inférieure ou égale à 10 ppm en masse et une teneur en eau inférieure ou égale à 10 ppm en masse.
