  • PROCESS FOR PRODUCING QUATERNARY AMMONIUM CATIONS AND IONIC LIQUIDS
    Publication number: 20170101375
    Abstract: The present invention provides a process and a method for producing a quaternary ammonium cation in an aqueous solution while reducing or preventing formation of a protonated ammonium cation. In particular, the quaternary ammonium cation is produced by adding a base to an aqueous reaction mixture comprising a tertiary amine compound and an alkylating agent.
