    摘要: An aromatic organic solvent solution of a methanesulfonic acid alkyl ester having high thermal stability is obtained by reacting an alkyl alcohol with methanesulfonyl chloride in an aromatic organic solvent in the presence of a tertiary amine, and washing the resulting aromatic organic solvent solution of a crude methanesulfonic acid alkyl ester with an aqueous alkali metal carbonate solution. The washing is performed using the aqueous alkali metal carbonate solution having a concentration of 1 to 3 mass% in an amount of 4 to 6 parts by mass per 1 part by mass of the alkyl alcohol.
