titleOfInvention | Process for preparation of alkyl methanesulfonate solution |
abstract | A heat-stable solution of an alkyl methanesulfonate in an aromatic organic solvent can be prepared by: reacting an alkyl alcohol with methanesulfonyl chloride in an aromatic organic solvent in the presence of a tertiary amine; and then subjecting the obtained solution of a crude alkyl methanesulfonate in the aromatic organic solvent to washing with an aqueous alkali metal carbonate solution. The washing is conducted using an aqueous alkali metal carbonate solution having a concentration of 1 to 3% by mass in an amount of 4 to 6 parts by mass per part by mass of the alkyl alcohol. |
