Process for producing a rubber anti-aging agent, a vulcanization accelerator or modified natural rubber by means of microorganism

Abstract

An object of the present invention is to provide processes for producing a rubber anti-aging agent, a vulcanization accelerator and a modified natural rubber, by converting glucose into benzoic acid or a benzoic acid derivative by a microorganism or extracting benzoic acid or a benzoic acid derivative from a plant, converting the obtained benzoic acid or benzoic acid derivative into aniline or an aniline derivative and then making the rubber anti-aging agent, vulcanization accelerator or modified natural rubber with the aniline or aniline derivative.

1 . A process for producing an antiaging agent, which process comprises:
 converting glucose into benzoic acid or a benzoic acid derivative by a microorganism other than  Streptomyces maritimus  and  Streptomyces coelicolor,  or   extracting benzoic acid or a benzoic acid derivative from a plant; and   converting the obtained benzoic acid or benzoic acid derivative into aniline or an aniline derivative.   
     
     
         2 . A process for producing a vulcanization accelerator, which process comprises:
 converting glucose into benzoic acid or a benzoic acid derivative by a microorganism other than  Streptomyces maritimus  and  Streptomyces coelicolor,  or   extracting benzoic acid or a benzoic acid derivative from a plant; and   converting the benzoic acid or benzoic acid derivative into aniline or an aniline derivative.   
     
     
         3 . A process for producing a modified natural rubber, which process comprises:
 converting glucose into benzoic acid or a benzoic acid derivative by a microorganism other than  Streptomyces maritimus  and  Streptomyces coelicolor,  or   extracting benzoic acid or a benzoic acid derivative from a plant;   converting the benzoic acid or benzoic acid derivative into aniline or an aniline derivative; and   modifying a natural rubber by the aniline or aniline derivative.
