Patent ID: 7897818

Claim:
A method for oxidizing hydrocarbon in liquid phase, comprising using a compound represented by formula (II) as an auxiliary agent to perform a liquid-phase oxidation reaction of the hydrocarbon in presence of an oxygen-containing gas and a cobalt halide as a catalyst: wherein R 6 , R 7 , R 8 , R 9 , R 10 , R 11 , R 12 and R 13 are independently selected from the group consisting of hydrogen, halogen, nitro, cyano, hydroxy, carbonyl, carboxyl, amino, amido, C 1 -6 alkyl, C 1-6 alkoxy, C 3-12 cycloalkyl, C 3-12 cycloalkoxy, C 3-12 cycloalkanoyl, C 6-20 aryl, C 7-20 arylalkyl, and C 7-20 alkylaryl, or R 6 and R 7 , R 7 and R 8 , R 8 and R 9 , R 10 and R 11 , R 11 and R 12 , or R 12 and R 13 are joined mutually to form an aromatic or non-aromatic ring, which is optionally substituted with halogen, nitro, cyano, hydroxy, carbonyl, carboxyl, amino, and/or amido, wherein the C 1-6 alkyl, C 1-6 alkoxy, C 3-12 cycloalkyl, C 3-12 cycloalkoxy, C 3-12 cycloalkanoyl, C 6-20 aryl, C 7-20 arylalkyl, and C 7-20 alkylaryl are optionally substituted with halogen, nitro, cyano, hydroxy, carbonyl, carboxyl, amino, and/or amido, and R 14 represents chemical bond, oxy, ester group, ketone group, pyridonyl, C 1-6 alkyl, C 1-6 alkenyl, C 1-6 alkylamino, C 1-6 alkoxy, C 1-6 alkanoyl, C 3-12 cycloalkyl, C 6-20 aryl, C 7-20 arylalkyl, or C 7-20 alkylaryl, wherein the C 1-6 alkyl and C 1-6 alkenyl are optionally substituted with halogen, nitro, cyano, hydroxy, carbonyl, carboxyl, amino, and/or amido.
