The present invention provides a novel oxygen absorbent composition being capable of realizing an oxygen absorbent not responding to a metal detector, being suppressed in the increase of the odor intensity after the absorption of oxygen and having an excellent oxygen absorption performance over a wide range of humidity conditions from low humidity to high humidity, and provides an oxygen absorbent package using the oxygen absorbent composition. The oxygen absorbent composition of the present invention includes at least one compound having a tetralin ring represented by the following general formula (1) and a transition metal catalyst:
(wherein, in formula (1), R1 to R8 each independently represent a hydrogen atom or a monovalent substituent; the monovalent substituent is the one selected from the group consisting of a halogen atom, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, a heterocyclic group, a cyano group, a hydroxy group, a carboxyl group, an ester group, an amide group, a nitro group, an alkoxy group, an aryloxy group, an acyl group, an amino group, a mercapto group, an alkylthio group, an arylthio group, a heterocyclic thio group and an imide group; these groups may further have a substituent(s) and two substituents of R1 to R8 may be bonded to each other to form a ring.)
本发明提供了一种新型吸氧剂组合物,该组合物能够实现对金属检测器无反应的吸氧剂,在吸收氧气后抑制气味强度的增加,并在从低湿度到高湿度的广泛湿度条件下具有优异的吸氧性能,本发明还提供了一种使用该吸氧剂组合物的吸氧剂包装。本发明的吸氧剂组合物包括至少一种具有如下通式(1)表示的四萘环的化合物和一种过渡金属催化剂:
(其中,在式 (1) 中,R1 至 R8 各自独立地代表一个氢原子或一个一价取代基;一价取代基是选自卤素原子、烷基、烯基、炔基、芳基、杂环基、氰基、羟基、羧基酯基、酰胺基、硝基、烷氧基、芳氧基、酰基、氨基、巯基、烷硫基、芳硫基、杂环硫基和亚胺基;这些基团可进一步具有一个或多个取代基,R1 至 R8 的两个取代基可相互键合形成一个环。)
