  S24/25:Berührung mit den Augen und der Haut vermeiden.

• Verwenden

  Sodium glucoheptonate is used for cleaning metal, mercerizing, paint stripping, and aluminum etching. It is also used to mercerize cotton, linen, hemp, and other plant-based fibers to increase strength and add luster to their overall appearance of threads and fabrics.

• Synthese

  98 g (2 mol) of sodium cyanide and 300 g of water were charged into a flask fitted with a stirrer, thermometer and a connection to a water jet aspirator. The contents of the flask were cooled to 2 ℃. using an ice bath. 396 g (2 mol) of dextrose hydrate were charged into the flask over about 30 minutes. When the sugar had all been charged, the temperature rose to 8 ℃., when the vacuum jet was turned on to provide a vacuum of about 40 mm of Hg. Within about 30 minutes, the temperature rose to 27 ℃., when the ammonia began to boil off vigorously. Within approximately 1 hour, the alpha sodium glucoheptonate dihydrate began to crystallize. The removal of the ammonia was continued at 27 ℃ and a vacuum of 33-40 mm of Hg for 6 hours. The crystals were filtered, water washed, and air dried. The first crop yield of alpha sodium glucoheptonate was -328 grams or 57.7% of the theoretical.
