• 敏感性LEAD PHOSPHITE, DIBASIC is self-reactive. A fiber drum of lead diphosphite caught fire apparently without any external cause. A gradual decomposition appears to have taken place, yielding lead phosphate, water, and phosphine. Phosphine, in turn, is spontaneously flammable in air and was probably the ignition source for the resulting fire [Kirk and Othmer 10:489. 1947]. Reacts violently with hydrogen sulfide [Bretherick 1979. p. 977-978].
