Abstract

PURPOSE: To provide the title cheap and safe compsn. capable of freely controlling its oxygen absorbing speed and vol., requiring addn. of no free water, and contg. an alkali metal sulfide and silica magnesia.
CONSTITUTION: To an alkali metal sulfide or polysulfide of formula MSx (where M; an alkali metal and x; a positive no. of 1W10) or a hydrate thereof are added ore based on silica and magnesia, and artificial ore contg. above 50 wt% of silica magnesia. As the alkali metal sulfide Na2S.9H2O is esp. suitable. To 1 part by wt. of the sulfide are added 0.01W100, pref. 0.05W50 parts of silica magnesia. Since most of the resulting compsns. change color when they absorb oxygen, by observing change of color we can confirm whether oxygen was absorbed or not. As the silica magnesia content is made higher, the oxygen absorbing speed of the resulting compsn. is increased.
