Patent ID: 8324341

Claim:
An alcohol solution of the agent serving as oxidant and dopant for conductive polymer production, comprising: an alcohol; and an agent serving as oxidant and dopant comprising a ferric salt of acids comprising a benzene sulfonic acid derivative represented by formula (1) and sulfuric acid, wherein “R” represents an alkyl or alkoxy group having a carbon number of 1 to 4, wherein more than 90 mole % of the benzene sulfonic acid derivative have R at the para position with respect to the SO 3 H group, wherein sulfuric acid is contained at 0.05 to 1.5 mass % in the acids, wherein an alkali metal and alkali earth metal as an inorganic alkali component are included at a total content between 38 ppm and 300 ppm (based on mass), wherein ammonia and an amine as an organic alkali component are included at a total content of 0.01 mole % or less, and wherein a pH value is 1.5 to 3.0 when the agent serving as oxidant and dopant is made into an aqueous solution at a concentration of 8 mass %, wherein the agent serving as oxidant and dopant is solved in the alcohol at a concentration of 30 mass % or more, wherein the alcohol solution has a water content of 5 mass % or less.
