ABSTRACT:
A process for producing alkali metal aminobutyrate or alkali metal aminobutyrate-alkali metal bisulfide complex by contacting an aqueous alkali metal hydroxide with NMP and optionally alkali metal bisulfide in a stirred reactor under reaction conditions to produce a predominantly one-phase system and maintaining these reaction conditions while passing the one-phase system through a disrupted flow tube reactor to complete the reaction. Dehydrating the reaction product in a two-stage dehydration process using a higher temperature in the second stage.
