Abstract
Sposób wydzielania 1,3-propanodiolu z brzeczki fermentacyjnej o zawartości 20-80 g/L 1,3-PD charakteryzuje się tym, że surowa brzeczka fermentacyjna podlega kolejno oddzieleniu zawiesin i koloidów znanymi metodami, odsoleniu wstępnemu metodą ekskluzji jonów przy pH > 7, odsoleniu całkowitemu metodą wymiany jonowej, odbarwianiu z użyciem żywic odbarwiających lub węgla aktywnego, zatężaniu próżniowemu w temperaturze poniżej 100°C i destylacji próżniowej w temperaturze 140-150°C.The method of separating 1,3-propanediol from a fermentation broth with a content of 20-80 g / L 1,3-PD is characterized by the fact that the raw fermentation broth is subjected to subsequent separation of suspensions and colloids by known methods, pre-desalting by ion exclusion at pH> 7, total desalting by ion exchange, decolorization using decolorizing resins or activated carbon, vacuum concentration at a temperature below 100 ° C and vacuum distillation at a temperature of 140-150 ° C.
