Versuchsvorschrift
In run 2, the aqueous NaOH and 12.5 gallons of NMP were charged to a separate stirred vessel (vessel 1) and contacted at 121° C. for 5 hours to form sodium N-methyl-4-aminobutyrate. The aqueous NaSH was then charged to the stirred vessel and the contents held for 30 minutes at 121° C. to form the polymerizable complex. The liquid mixture was then transferred to the polymerization reactor containing 6 gallons of NMP and 23 lb (0.28 lb-mole) of NaOAc through a Cuno Inc., Process Filtration Products 316 SS porous metal cartridge filter having nominal openings of five microns to remove metal impurities. The stirred vessel was then flushed with 17.7 gallons of NMP through the filter to the polymerization reactor.
