Abstract

An oxygen absorbing agent composition including at least one type of a compound having an indane skeleton represented by the following general formula (1) and a transition metal catalyst:

First claim

The invention claimed is:

1. An oxygen absorbing agent composition comprising at least one compound having an indane skeleton represented by the following formula (1), a transition metal catalyst, and a carrier substance supporting the at least one compound having an indane skeleton:

wherein, in the formula (1), R 1 to R 10 are each independently a hydrogen atom or a monovalent substituent; the monovalent substituent is at least 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 thiol group, an alkylthio group, an arylthio group, a heterocyclic thio group, an imide group, a substituent represented by the following formula (1a) and a substituent represented by the following formula (1b); these groups may further have a substituent, and two substituents of R 1 to R 10 may be bonded to each other to form a ring;
to the benzylic positions in the indane skeleton, at least one or more hydrogen atoms are bonded;

wherein, in the formula (1a) and the formula (1b), each R independently represents a monovalent substituent; the monovalent substituent is at least one selected from 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 thiol group, an alkylthio group, an arylthio group, a heterocyclic thio group and an imide group; the groups may further have a substituent, and two substituents may be bonded to each other to form a ring;
W is an atomic bond or a divalent organic group; the divalent organic group is at least one selected from the group consisting of an aromatic hydrocarbon group, a saturated or unsaturated alicyclic hydrocarbon group, a linear or branched, saturated or unsaturated aliphatic hydrocarbon group, a heterocyclic group, —C(═O)—, —OC(═O)—, and —N(H)C(═O)—, and optional combinations of these;
m represents an integer of 0 to 4, n represents an integer of 0 to 5, p represents an integer of 0 to 6, and q represents an integer of 0 to 3; and
the carrier substance comprises at least one selected from the group consisting of synthetic calcium silicate, hydrated lime, activated carbon, zeolite, perlite, diatom earth, activated clay, silica, kaolin, talc, bentonite, activated alumina, gypsum, silica alumina, calcium silicate, magnesium oxide, graphite, carbon black, aluminum hydroxide and iron oxide.

2. The oxygen absorbing agent composition according to claim 1 , wherein the transition metal catalyst is further supported by the carrier substance.

3. The oxygen absorbing agent composition according to claim 1 , wherein the transition metal catalyst comprises at least one transition metal selected from the group consisting of manganese, iron, cobalt, nickel and copper.

4. The oxygen absorbing agent composition according to claim 1 , wherein a mixing amount of the transition metal catalyst is 0.001 to 10 parts by mass in terms of the transition metal amount, based on 100 parts by mass of the compound having the indane skeleton.

5. The oxygen absorbing agent composition according to claim 1 , wherein the carrier substance is at least one selected from the group consisting of synthetic calcium silicate, diatom earth, silica and activated carbon.

6. The oxygen absorbing agent composition according to claim 1 , wherein a mixing amount of the carrier substance is 10 to 1000 parts by mass based on 100 parts by mass of the compound having the indane skeleton.

7. An oxygen absorbing agent package formed by packaging the oxygen absorbing agent composition according to claim 1 with an air permeable packaging material.
