Patent ID: 8847000

Claim:
A composition for alkylating a harmful compound containing at least one element selected from the group consisting of arsenic, antimony and selenium to detoxify the harmful compound, comprising: a cobalt complex; a first reducing agent that is capable of reducing at least one metal selected from the group consisting of arsenic, antimony and selenium, a second reducing agent that is capable of reducing the cobalt complex and is at least one selected from the group consisting of titanium oxide and ruthenium complex, at least one organic halide compound selected from the group consisting of methyl chloride, methyl bromide, methyl iodide, chloroacetic acid, bromoacetic acid, iodoacetic acid, chloroethanol, bromoethanol, iodoethanol, chloropropionic acid, bromopropionic acid, iodopropionic acid, chloroacetic acid ethyl ester, bromoacetic acid ethyl ester and iodoacetic acid ethyl ester, wherein the composition is capable of alkylating a harmful compound containing at least one element selected from the group consisting of arsenic, antimony and selenium to detoxify the harmful compound, and wherein the cobalt complex is at least one selected from (1) an organometallic-cobalt complex having a cobalt-carbon bond comprising at least one compound selected from the group consisting of methylcobalamin (methylated vitamin B12, official name: Coα-[α-5,6-dimethylbenz-1H-imidazole-1-yl-Coβ-methylcobamide]), vitamin B12, cobalt(II) acetyl acetonate, cobalt(III) acetyl acetonate, cobalt carbonyl (dicobalt octacarbonyl), cobalt(II) 1,1,1,5,5,5-hexafluoro acetyl acetonate, cobalt(II) meso-tetra phenyl porphin, hexafluoro phosphoric acid bis (pentamethyl cyclopenta dienyl) cobalt, N, N′-bis (salicylidene) ethylene diamine cobalt(II), bis (2,2,6,6-tetramethyl-3,5-heptanedionato) cobalt(II), (chlorophthalocyaninnato) cobalt(II), chlorotris (triphenylphosphine) cobalt(I), methyl complex of cobalt(II) acetate, cobalt(II) benzoate, cobalt(II) cyanide, cyclohexane cobalt(II) butyrate, 2-cobalt(II) ethylhexanoate, meso-tetramethoxyphenyl porphyrin cobalt(II), cobalt naphthenate, cobalt(II) phthalocyanine, methyl cobalt(III) protoporphyrin IX, cobalt stearate, cobalt(II) sulfamate, (1R, 2R)-(−)01,2-cyclohexanediamino-N,N′-bis (3,5-di-t-butylsalicylidene) cobalt(II), (1S, 2S)-(+)-1,2-cyclohexanediamino-N,N′-bis (3,5-di-t-butylsalicylidene) cobalt(II), cyclopentadienyl bis (triphenylphosphine) cobalt(I), cyclopentadienyl cobalt dicarbonyl, dibromo bis (triphenylphosphine) cobalt(II), (tetraaminochloro phthalocyaninnato) cobalt(II), and (tetra-t-butyl phthalocyaninnato) cobalt(II), and (2) a cobalt-methyl complex formed by allowing a cobalt compound to coexist with an alkyl halide.
