Abstract
PURPOSE: To provide the title cheap compsn. capable of freely controlling its oxygen absorbing speed and vol., and requiring addn. of no free water by adding silica and/or alumina to an alkali metal sulfide.
CONSTITUTION: An alkali metal sulfide, an alkali metal polysulfide or a hydrate thereof is used, and Na2S.9H2O is effective and cheap. The alkali metal includes Li, Na, K, Ce, etc. The sulfide, etc. do not readily absorb oxygen at ordinary temp. even if exposed to an oxygen atmosphere, and hence they are relatively stable cpds. By being combined with silica or alumina the sulfide, etc., however, readily absorb oxygen at ordinary temp. To 1 part by wt. of an alkali metal sulfide are added 0.01W100, pref. 0.05W50 parts of silica and/or alumina. As the silica and/or alumina content is made higher, the oxygen absorbing speed of the resulting compsn. is increased, yet too high content reduces oxygen absorbing vol. per unit compsn. wt.
