The present invention provides a synthesis system that can synthesize aniline and/or styrene efficiently, a synthesis system that can synthesize butadiene (1,3-butadiene) efficiently, a rubber chemical for a tire which is synthesized from the aniline obtained by the synthesis system, a synthetic rubber for a tire which is synthesized from the styrene and/or butadiene obtained by the synthesis systems, and a pneumatic tire produced using the rubber chemical for a tire and/or the synthetic rubber for a tire. The present invention relates to a synthesis system for synthesizing aniline and/or styrene from an alcohol having two or more carbon atoms via an aromatic compound.

The object of the present invention is to provide processes for producing an antiaging agent, a vulcanization accelerator and a modified natural rubber, which are environmentally friendly and allow to make provision against a decrease of petroleum resources in the future. According to the present invention, glucose is used as carbon neutral resources and is converted into aniline or an aniline derivative by a microorganism. An antiaging agent, a vulcanization accelerator or a modified natural rubber is produced from thus obtained aniline or aniline derivative.

Process for producing antiaging agent, vulcanization accelerator or modified natural rubber by means of microorganism

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 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.
