  • the ammonia content of the distillate was then determined via titration. The results were recorded in Tables 1 and 2.
  • This example used a DAS-containing, clarified fermentation broth derived from a fermentation broth containing E. coli strain ATCC PTA-5132.
  • the initial fermentation broth was clarified, thereby resulting in a clarified fermentation broth containing about 4.5% DAS. That clarified broth was used to produce crystalline SA as follows.
  • the broth was first concentrated to approximately 9% using an RO membrane and then subjected to distillation at atmospheric pressure to further concentrate the broth to around 40%.
  • the concentrated broth was used as the starting material for conversion of DAS to SA, carried out batchwise in a 300 ml Parr reactor. A 200 g portion of the solution was reacted at 200°C/200 psig for 11 hours. As the reaction proceeded, water vapor and ammonia liberated from the DAS were condensed and collected overhead. Condensate was collected at about 2 g/min, and makeup water was fed back to the system at approximately the same rate.
  • a 500 mL round bottom flask was charged with 80g of an aqueous 36% DAS solution and 80g of triglyme.
  • the flask was fitted with a 5 tray 1" glass Oldershaw column section which was topped with a distillation head.
  • An addition funnel containing 3300g of water was also connected to the flask.
  • the flask was stirred with a magnetic stirrer and heated with a heating mantel.
  • the distillate was collected in an ice cooled receiver. When the distillate started coming over the water in the addition funnel was added to the flask at the same rate as the distillate was being taken. A total of 3313g of distillate was taken.
  • the distillate contained 4.4g of ammonia, as determined by titration.
  • a pressure distillation column was made using an 8 ft long 1.5" 316 SS Schedule 40 pipe packed with 316 SS Propak packing.
  • the base of the column was equipped with an immersion heater to serve as a reboiler. Nitrogen was injected into the reboiler via a needle valve to pressure.
  • the overhead of the column had a total take-off line which went to a 316 SS shell and tube condenser with a receiver.
  • the receiver was equipped with a pressure gauge and a back pressure regulator. Material was removed from the overhead receiver via blowcasing through a needle valve. Preheated feed was injected into the column at the top of the packing via a pump along with a dilute 0.4% sodium hydroxide solution.
  • Preheated water was also injected into the reboiler via a pump.
  • This column was first operated at 50 psig pressure which gave a column temperature of 150° C.
  • the top of the column was fed a 4.7% DAS containing broth at a rate of 8 mL/min along with 0.15 mL/min of 0.4% sodium hydroxide solution.
  • Water was fed to the reboiler at a rate of 4 mL/min.
  • the overhead distillate rate was taken at 8 mL/min and the residue rate was taken at 4 mL/min.
  • a total of 2565g of broth was fed to the column along with 53g of 0.4% sodium hydroxide solution.
  • a total of 2750g of distillate was taken and 1269g of residue taken during the run.

Abstract

La présente invention concerne des procédés consistant à fournir un succinate de diammonium (DAS), ou un succinate de mono-ammonium (MAS), clarifié contenant un bouillon de fermentation; à distiller le bouillon d'un distillat de tête qui comprend de l'eau et de l'ammoniac, et un fond liquide qui contient SA, et au moins 20 % en poids d'eau; à refroidir le fond à une température suffisante pour provoquer la séparation du fond en une partie liquide en contact avec une partie solide qui est du SA sensiblement pur; à séparer la partie solide de la partie liquide; et à convertir la partie solide pour produire des composés contenant de l'azote tels que du diaminobutane (DAB), du dinitrile succinique (SDN), de l'aminonitrile succinique (SAN) ou du succinamide (DAM) et des produits en aval.
